Rib remodelling and RibXcar in Switzerland: understanding the waist at rib level

Some people find that, despite a low weight, a flat stomach and slim flanks, their waist remains wide. When they place their hands on their lower chest, they feel ribs that flare outwards, just above the waist. This shape, often described as flared ribs, limits how slim the waist can be regardless of fat. Rib remodelling covers the approaches that seek to act on this bony component: from posture and breathing exercises when the flaring is functional, to surgical techniques that alter the curvature of the lower ribs, the most publicised of which is known as RibXcar. This field is attracting growing interest, but it is still recent, and long-term knowledge remains limited. This page explains what determines the width of the waist at rib level, how to tell postural flaring from a bony shape, what options exist, from physiotherapy to surgery, what is known and what is still unknown, and how to find your way in Switzerland, with price benchmarks expressed as differences relative to Geneva.

Rib remodelling aims to reduce the width of the lower chest when the lower ribs are flared. When the flaring is linked to posture or breathing, physiotherapy can improve it without surgery. When it is bony, recent surgical techniques such as RibXcar alter the curvature of a few lower ribs through small incisions, often under guidance, followed by wearing a corset for several weeks. These techniques are still recent: published results are limited and the risks, including injury to the pleura and prolonged pain, must be well understood. Rib remodelling is often combined with waist liposuction, described on our page RibXcar combined with liposuction. Detailed budget: rib remodelling prices in Switzerland.

Waist width is the sum of three components. The first is fat under the skin and inside the abdomen, which is influenced by diet, exercise and, for fat under the skin, liposuction. The second is the muscular wall, whose tone and posture influence the shape of the stomach and waist. The third is the skeleton: the shape of the ribcage, the spread of the lower ribs and the width of the pelvis. Rib remodelling only addresses part of this third component. It only makes sense once the first two have already been optimised.

The hourglass figure is characterised by a waist that is markedly narrower than the bust and hips. It depends largely on basic body shape: the width of the shoulders, ribcage and pelvis. Some people naturally have a narrow chest and a wide pelvis, others a straighter silhouette. Surgery can accentuate the curve by reducing waist fat and, in some cases, rib flaring, but it does not transform a body type. Our page on body contouring presents the different body shapes and the reshaping options.

The impression of a slim waist depends less on the absolute waist measurement than on the proportions between waist, bust and hips. Reducing the waist by three centimetres can transform a silhouette with a wide pelvis, and change a straight silhouette very little. Conversely, slightly increasing the volume of the hips or buttocks with fat transfer can accentuate the curve without touching the ribs. The surgeon thinks in terms of proportions and sometimes suggests a different approach from the one initially envisaged.

Ribs are described as flared when the lowest ribs, which form the margin of the chest just above the waist, project forwards and outwards instead of following a gentle inward curve. From the front, the lower chest looks wide; in profile, the rib margin may protrude under the skin, especially when lying down. This appearance may be constitutional, present from the outset, or may have developed over time, after a pregnancy, a change in posture or a breathing pattern that mainly uses the upper chest. Distinguishing between these situations is essential, as it determines the treatment.

The angle formed by the two rib margins below the sternum, called the subcostal angle, is a useful reference point. When it is closed, in a narrow V shape, the waist looks slimmer; when it is open, in a wide V shape, the lower chest looks wide. This angle depends on body shape, posture and breathing. It can partly close with rehabilitation when it has opened for functional reasons, for example after a pregnancy. The physiotherapist observes it to monitor progress.

Rib remodelling attracts attention, often through spectacular images. But most people who wonder about the width of their waist do not need surgery on their ribs, and the technique is still recent. That is why this page emphasises assessment, rehabilitation and alternatives before presenting surgery. The aim is to help everyone make an informed choice suited to their situation, not to promote a procedure.

The ribcage is made up of twelve pairs of ribs, connected at the back to the spine. The first seven pairs attach at the front to the sternum by cartilage. The eighth, ninth and tenth pairs join the cartilage of the ribs above and together form the rib margin, the oblique ridge you can feel below the chest. The eleventh and twelfth pairs, known as floating ribs, are not attached to the sternum: they end freely in the flank muscles. It is mainly these lower ribs, from the tenth to the twelfth, that determine the width of the chest at waist level.

The ribcage is not a rigid structure: its ribs articulate with the spine at the back and with the sternum at the front via flexible cartilage. This mobility allows breathing, rotation and bending of the torso. The lower ribs, and especially the floating ribs, are particularly mobile. This mobility explains why part of the flaring can be corrected through posture and breathing. It is also what makes pain after a procedure so sensitive to movement.

The ribs from the eighth to the tenth are connected to each other and to the sternum by cartilage, which forms the rib margin. This cartilage, flexible in young people, becomes more rigid with age. Its shape contributes greatly to the appearance of the rib margin. Remodelling techniques act mainly on the bone of the lower ribs and on the floating ribs, and less on the cartilage of the margin, which sometimes limits the effect on a margin that protrudes markedly at the front.

The lower ribs partly protect important organs: the liver on the right, the spleen on the left, the kidneys at the back, and the lower part of the lungs. The floating ribs, in particular, cover the upper part of the kidneys. This is one of the reasons why removing these ribs is now discouraged, and why remodelling seeks to preserve their continuity. The long-term consequences of changing their shape on this protection have been little studied.

Many muscles attach to the lower ribs: the diaphragm on their inner surface, the oblique and transversus abdominis muscles, the latissimus dorsi and some back muscles. Their tone and balance influence the position of the ribs. Balanced strengthening of these muscles helps bring the ribs inwards. After a procedure, these muscles are engaged with every movement, which explains part of the pain.

The shape of the ribcage varies greatly from person to person. Some chests are narrow and elongated, with lower ribs that slope down obliquely towards a defined waist. Others are wider and shorter, with horizontal lower ribs that widen the lower chest. Others still are flared at the bottom, with an open rib margin. These shapes are largely hereditary. They explain why two people of the same weight and musculature do not have the same waist.

The waist lies in the space between the bottom of the ribs and the top of the pelvis. When this space is long, the waist can curve in more; when it is short, the lower ribs are close to the pelvis and the waist looks less defined. This distance depends on the length of the torso and spine, and on posture. It cannot be changed surgically, but an upright posture, which lengthens the torso, can increase it slightly.

The ribs move with every breath. On inhalation, they rise and spread apart, and the ribcage widens; on exhalation, they lower and come together. The diaphragm, the main breathing muscle, attaches to the inner surface of the lower ribs. When breathing is mainly thoracic and high, with a poorly mobile diaphragm, or when the tone of the deep abdominal muscles is weak, the lower ribs can remain in the inhalation position, flared, even at rest. In this case, the flaring is partly functional and can improve with breathing rehabilitation.

Posture strongly influences the position of the ribs. A pronounced lumbar arch, often associated with a forward-tilted pelvis, makes the rib margin rise and stick out. A hyperextended back posture, common among dancers, gymnasts or people who stand very upright with their chest thrust out, has the same effect. Conversely, a stooped posture can mask flaring. Correcting posture often visibly changes the appearance of the lower chest, which shows the functional share of the flaring.

The posture adopted every day, at the office, when driving or in front of a screen, has a lasting influence on the position of the ribs. A slumped sitting position, with the pelvis tilted back, compresses the abdomen; an arched position makes the rib margin stick out. A few habits help: sitting at the back of the seat with a neutral pelvis, placing your feet flat, positioning the screen at eye level, getting up regularly and taking a few deep breaths. These small adjustments contribute to a better rib position.

Parents of young children often adopt postures that encourage flaring: carrying the child on one hip while arching the back, leaning back to compensate for its weight, breathing high while carrying. Becoming aware of these postures, carrying the child close to the body while keeping the pelvis neutral and using a suitable baby carrier contribute to a better rib position and protect the back.

High-heeled shoes accentuate the lumbar arch and tilt the pelvis forwards, which can make the rib margin stick out. Regularly wearing high heels can therefore contribute to functional flaring. Alternating with flat shoes, strengthening the abdominal wall and working on posture limit this effect. This often overlooked detail is part of the overall postural assessment offered by the physiotherapist.

Regularly carrying a heavy bag on one shoulder, or a loaded, poorly adjusted backpack, changes posture: the torso leans, the pelvis tilts and breathing becomes higher. Distributing the load, lightening your bag and adjusting the straps contribute to better posture and, indirectly, to a better rib position.

Hours spent in front of a computer or phone encourage a slumped posture, with the head forward and shoulders rounded, and short, high breathing. This posture alters the balance of the ribcage. Positioning the screen at eye level, straightening up regularly, taking a few deep breaths every hour and getting up to walk contribute to better posture and more efficient breathing, at work as at home, and usefully complement the rehabilitation exercises suggested by the physiotherapist, without requiring much time each day or any special equipment, whether at home or in the office.

Beyond the exercises, adopting fuller, lower breathing in everyday life, particularly in stressful moments when we tend to breathe from the upper chest, helps engage the diaphragm and bring the ribs inwards. A few slow breaths, several times a day, are enough to establish this habit. This work also has beneficial effects on relaxation and stress management.

Stress changes the way we breathe: breathing becomes faster and higher, using the neck and upper chest muscles rather than the diaphragm. The ribs then remain in the inhalation position, open. In people with chronic stress, this high breathing can contribute to functional flaring and muscle tension. Learning to breathe slowly, using the diaphragm, has a double benefit: for rib position and for stress management.

Singers and wind instrument players work extensively on their breathing, often with a strong development of chest capacity. In some, this is accompanied by a more open ribcage. For them, surgery on the ribs could have consequences for their musical practice that are still poorly documented. A thorough discussion with the surgeon and, if possible, with a voice specialist is essential before any decision.

Some clothes emphasise or conceal the width of the lower chest. Clothes fitted just below the bust, belts worn at the natural waist and cuts that follow the body's line accentuate the waist; straight cuts or clothes that are tight at rib level make it look wider. These choices do not change the body, but they can markedly change the perception of the silhouette, in addition to or instead of a procedure.

During pregnancy, the uterus pushes the organs upwards, and the ribcage widens to leave room for breathing; the chest circumference at the lower ribs increases by several centimetres. After childbirth, the ribcage often returns to its shape, but not always completely: flaring may persist, with or without separation of the abdominal muscles. Abdominal and breathing rehabilitation is the first step. It often improves the situation and makes it possible to assess what remains.

During pregnancy, hormones soften the ligaments and cartilage, and the growing uterus pushes the diaphragm upwards. To maintain sufficient breathing, the ribcage widens: the angle formed by the rib margin below the sternum opens, and the chest circumference at the lower ribs increases. After childbirth, this process gradually reverses, but it may remain incomplete, particularly when the abdominal wall is weakened. This is why abdominal and breathing rehabilitation is so important in the following months.

Flaring of the lower ribs and separation of the rectus abdominis muscles are often associated, particularly after a pregnancy. When the midline of the abdomen is stretched, the abdominal muscles pull less effectively on the rib margin, which opens further. Rehabilitation works on both at the same time. When the separation persists and there is excess skin, a tummy tuck with muscle repair may be considered; it sometimes also improves the position of the lower ribs. Our page on the tummy tuck describes this procedure.

After each pregnancy, rehabilitation of the pelvic floor, abdominal wall and breathing is recommended. It helps close the muscle separation, restore diaphragmatic breathing and bring the ribs back into position. Started a few weeks after childbirth, as advised by the midwife or doctor, it often prevents lasting flaring from developing.

In some people, the flared shape of the lower ribs has been present since childhood, linked to the shape of the ribcage. It may be more or less pronounced, sometimes asymmetrical. It does not improve with posture or breathing, as it is due to the shape of the bones and cartilage. It is in this situation that surgical remodelling techniques may be discussed, when the concern is significant and after a thorough assessment.

Certain chest shapes require specific medical treatment: a funnel chest, with a sunken sternum, is often accompanied by protruding lower ribs; a pigeon chest, with a bulging sternum; scoliosis, which can make the chest asymmetrical, with a rib prominence on one side. These situations are assessed by thoracic or orthopaedic surgeons and do not fall within a cosmetic approach to the waist. An examination and sometimes imaging make it possible to identify them.

If the rib margin looks prominent because of a sunken or bulging sternum, or if there is significant asymmetry, it is often a chest deformity that requires a specialist opinion, in thoracic surgery or orthopaedics. These deformities can have functional consequences and have specific treatments, sometimes covered by insurance. It is important not to confuse them with simple cosmetic flaring.

Thoracic surgeons are specialists in the ribcage, lungs and pleura. They treat chest deformities, such as funnel chest or pigeon chest, and pleural complications. Some rib remodelling teams work with them to assess complex cases or manage any complications. It is useful to know whether such collaboration exists within the team you consult.

The first step in any approach is to understand the origin of the flaring. A few observations can give you an idea, but assessment by a professional, physiotherapist or doctor, remains necessary.

The physiotherapist or surgeon observes the standing posture, from the front and in profile: pelvic position, lumbar curve, position of the ribcage relative to the pelvis, position of the shoulders and head. They also assess breathing at rest and during forced exhalation. This assessment makes it possible to quantify the postural share of the flaring and propose a suitable rehabilitation programme.

In most consultations for a wide waist, the examination shows that fat on the flanks, back and stomach accounts for most of the width. The rib margin, felt beneath a layer of fat, sometimes seems more prominent than it is. Well-performed waist liposuction, with or without definition, can then produce a markedly slimmer waist without touching the ribs. This is the first option to consider. Our page on liposuction presents this procedure.

Fat inside the abdomen, around the organs, widens the waist from within and pushes the abdominal wall forwards. It is accessible neither to liposuction nor to rib remodelling. Reducing it involves diet, physical activity and, if necessary, medical treatment. A firm, rounded stomach that cannot be pinched is often a sign of it. Before any waist surgery, it is useful to check that it is not the main cause of the width.

Standing in front of a mirror, place your hands on the rib margin, then exhale slowly and completely, as if emptying your lungs, while gently drawing in your navel. If the ribs draw together clearly and the margin disappears, a large part of the flaring is probably functional. Repeat while correcting your posture, with your pelvis in a neutral position, without arching your lower back. This test does not replace an examination, but it helps you understand the role of posture and breathing.

When the flaring is partly functional, physiotherapy is the first response, before any surgery. The physiotherapist works on breathing, teaching you to use the diaphragm and exhale completely; on strengthening the deep abdominal muscles, particularly the transversus and obliques, which bring the ribs inwards; and on posture, correcting the lower-back arch and pelvic position. This work requires several months of regular practice. It can visibly reduce flaring and the width of the lower chest, without risk.

Rehabilitation of functional flaring often begins with breathing. Lying on your back, knees bent, place one hand on your stomach and the other on your lower ribs. On inhalation, let your stomach and ribs open to the sides and towards the back, without lifting your shoulders. On exhalation, slow and complete, as if blowing through a straw, feel your ribs drawing together and lowering, and your stomach gently drawing in. Repeated for a few minutes a day, this exercise retrains the body to breathe in a way that engages the diaphragm and brings the ribs inwards.

Active exhalation is one of the most useful exercises for bringing the lower ribs inwards. Lying on your back, knees bent, feet on the floor, breathe in through your nose, letting your ribs open to the sides. Then breathe out slowly through your mouth, as if blowing on a candle without putting it out, feeling your ribs lower and draw together, and your lower stomach gently draw in. Hold the end of the exhalation for a few seconds before breathing in again. Repeated ten times, twice a day, this exercise teaches the abdominal muscles to hold the ribs in a low position.

The obliques are the muscles that lower and draw in the rib margin. A simple exercise involves lying on your back, knees bent, and exhaling while gently bringing one shoulder towards the opposite knee, without pulling on your neck, then returning while inhaling. Another involves doing a side plank on your forearms, with your knees on the floor at first, while exhaling. These exercises, performed slowly and with good breathing, are more useful than many fast repetitions.

An excessive arch, often associated with a forward-tilted pelvis, makes the lower ribs stick out. Lying on your back, knees bent, you learn to gently tilt your pelvis to press your lower back into the floor while exhaling, then release. Standing, you look for a neutral position, neither arched nor flattened. Strengthening the glutes and stretching the muscles at the front of the hips complete this work.

The exercises only bear fruit if they are practised regularly. Fitting them into set times of the day, on waking, before bed, during a break at work, helps make them automatic. Thinking about your breathing and posture in everyday movements, when walking, carrying a bag or waiting for the bus, extends the effects. After a few months, these habits become natural.

During rehabilitation, it is useful to measure your waist and the circumference at the lower ribs once a month, under the same conditions, and to take photos from the front and in profile. These objective markers often show gradual improvement, sometimes greater than you perceive day to day. They also help the physiotherapist adapt the programme and the surgeon assess, where appropriate, the remaining share of the flaring.

Strengthening the deep muscles of the abdominal wall, particularly the transversus and obliques, helps bring the ribs inwards and stabilise the waist. The exercises focus on control and breathing rather than brute strength: gentle core work while exhaling, pelvic tilts, controlled rotation exercises, work on all fours. Classic sit-ups, performed while holding the breath, are less useful and can sometimes accentuate the forward push.

Habitual posture influences the position of the ribs day to day. Postural work aims to place the pelvis in a neutral position, without excessive arching, to align the ribcage above the pelvis, and to relax the shoulders. Awareness exercises in front of a mirror, hip flexor stretches and glute strengthening contribute to this. This work pays off over time, provided it is integrated into everyday movements, both sitting at the office and standing.

To give you an idea of rehabilitation, here is an example of a weekly schedule, to be adapted with the physiotherapist.

The first changes in rib position can appear within a few weeks, notably thanks to better postural awareness. A clearer improvement generally requires three to six months of regular practice. Progress is faster when the flaring is recent, for example after a pregnancy, and slower when it is long-standing. Measuring your waist and taking regular photos helps you assess progress.

Several professionals can support rehabilitation: physiotherapists, particularly those trained in breathing, abdominal or pelvic floor rehabilitation, qualified Pilates instructors, and sometimes osteopaths. For flaring after pregnancy or associated with abdominal muscle separation, a physiotherapist specialising in postnatal rehabilitation is particularly suitable. Physiotherapy on medical prescription may be covered, subject to the conditions in force.

Some people consult an osteopath or manual therapist to improve ribcage mobility and posture. These approaches can provide comfort, as a complement to active rehabilitation. They do not change the bony shape of the ribs. It is preferable to combine them with active breathing and strengthening work, which gives longer-lasting results.

Some sporting activities can accentuate flaring: sports involving back hyperextension, weight training focused on developing the latissimus dorsi and pectorals without working the deep abdominal muscles, or very thoracic breathing during exertion. Conversely, Pilates, yoga, swimming and balanced abdominal strengthening promote a better-positioned rib margin. Adapting your training, with the help of a professional, is part of the non-surgical approach.

Pilates focuses on control of the deep muscles, lateral breathing, which opens the ribs out to the sides rather than forwards, and alignment of the pelvis and spine. These principles match exactly the work that is useful for functional flaring. Yoga, with its breathing and posture exercises, complements this approach. To get the most out of it, it is advisable to choose a qualified teacher, tell them your goal, and start with individual or small-group sessions.

Lateral breathing means breathing in by opening the ribs out to the sides and towards the back, rather than pushing the chest forwards, then breathing out by drawing them back in. It is used in Pilates and in rehabilitation. In practice, you place your hands on the lower ribs, at the sides, and try to spread them gently as you breathe in, then bring them together as you breathe out, without lifting the shoulders. This exercise improves control of the rib cage and helps correct forward flaring.

When retraining rib flaring, consistency matters more than intensity. Ten minutes of exercises every day gives better results than one intense hour once a week. The deep muscles and breathing habits are built through repetition. Setting a short, realistic routine and sticking to it over several months is the key to progress.

After the first learning sessions, it is useful to see the physiotherapist again regularly, for example once a month, to check that the exercises are being done correctly, adapt the programme and measure progress. In the event of pain, difficulty doing the exercises or no progress after a few months, a consultation allows the approach to be adjusted or a referral for a medical assessment.

Endurance athletes, such as swimmers, runners and cyclists, place heavy demands on their breathing. A mobile, expansive rib cage is an asset for their performance. In these athletes, a flared costal margin is often linked to this adaptation. Rib surgery, with its long healing period and its uncertainties regarding breathing, is rarely compatible with intensive sport.

Wearing tight corsets for long periods, often presented as a way to slim the waist, is not recommended. It compresses the lower ribs and the organs, restricts breathing, weakens the abdominal muscles and can cause pain, digestive problems and skin irritation. Any effect on the shape of the waist is temporary and disappears once you stop. The medical corset worn after rib surgery has a different purpose: it holds the ribs in their new position while they heal, under medical supervision.

Rib remodelling surgery may be considered when the flaring is mainly bony, when well-conducted rehabilitation has not brought sufficient improvement, when the concern is significant, when waist fat has been reduced and weight has stabilised, and when the person understands the uncertainties and risks of a technique that is still recent. It remains an aesthetic procedure, which is never essential. A thorough assessment, often with imaging, precedes any decision.

Before considering rib remodelling, several options can slim the waist or enhance curves: reducing fat through diet and physical activity, liposuction of the flanks, back and abdomen, female definition liposuction, fat transfer to the hips or buttocks, and breathing and postural rehabilitation. These simpler, better-known options are sufficient in most cases.

Our pages on 360 liposuction and buttock fat transfer present two of these options.

The pursuit of an extremely small waist goes through waves of popularity, often driven by media personalities and social media. These trends pass, whereas surgery on the skeleton is lasting. It is worth asking yourself whether your wish is deep-seated and lasting, or influenced by a fashion. Sufficient time to reflect and a frank discussion with the surgeon help to tell the difference.

The ideal of a very small waist has spanned the centuries, with corsets laced tightly from childhood by some women in past centuries, which deformed the rib cage and caused numerous disorders. Rumours long circulated about celebrities who had supposedly had ribs removed, mostly without foundation. Current remodelling techniques are part of a regulated medical approach, very different from these practices, but history is a reminder of the risks of an excessive quest for a slim waist.

For decades, rumours have circulated about celebrities who supposedly had ribs removed to slim their waist. Most of these stories are not based on any verified information. Yet they have helped create the belief that a very small waist could easily be achieved by surgery on the ribs. The reality is different: very defined figures often come down to body shape, posture, sport, clothing, lighting and sometimes photo editing. Current, more measured remodelling techniques do not transform a figure spectacularly.

Many images of figures with very small waists, published on social media or in the media, are edited or achieved through carefully chosen angles and poses. Comparing yourself to these images can create unrealistic expectations and dissatisfaction with your own body. It is worth bearing in mind that most real bodies do not look like these images, and that health and comfort matter more than conforming to an ideal.

Several surgical approaches have been proposed to reduce the width of the lower ribs. They differ in their principle and their invasiveness.

RibXcar is the name of a lower-rib remodelling technique developed in recent years. The surgeon accesses a few lower ribs, usually the tenth to the twelfth, through very small incisions, and uses an ultrasonic instrument to create small, controlled partial breaks in the rib, making it more flexible. The rib is then directed inwards, and a corset is worn for several weeks to hold the new curvature while the bone heals. The aim is to reduce the width of the lower chest by a few centimetres. The procedure is often combined with waist liposuction in the same session.

Ultrasonic instruments used in bone surgery, sometimes called piezosurgery, cut bone using very high-frequency vibrations, while relatively sparing soft tissues such as nerves, vessels and membranes, which vibrate with the instrument without being cut. This selectivity explains their value close to the pleura and the intercostal nerves. They have been used for years in other fields, such as dental and maxillofacial surgery. Their application to rib remodelling is more recent.

The idea of remodelling is to weaken the rib at certain points, with small notches or partial breaks, so that it can be bent slightly inwards without being cut through completely. The rib thus retains a continuity that helps it heal in its new position. The number and location of the notches, as well as the force applied, are adapted to each rib. The corset then takes over to hold the curvature during healing.

Remodelling involves a small number of lower ribs, because these are what determine the width at the waist, and because treating more ribs would increase the risks, the pain and the impact on breathing. The higher ribs, attached to the sternum, play a greater role in breathing mechanics and in protecting the chest organs. A limited, targeted approach is therefore the rule.

Historically, some people resorted to having part of the floating ribs removed to slim their waist. This more invasive procedure is surrounded by many misconceptions and rumours. It carries significant risks: prolonged pain, damage to the pleura, the intercostal nerves or neighbouring organs, and loss of the protection these ribs provide for the kidneys and other organs. It is rarely offered in aesthetic surgery today, with less invasive remodelling techniques being preferred by the teams interested in this field.

The ribs are close to the pleura, the membrane surrounding the lungs, as well as to the intercostal vessels and nerves. To limit the risks, teams performing rib remodelling use precise instruments and often ultrasound guidance, which allows the rib and neighbouring structures to be visualised. The team's experience and the precision of the procedure are decisive for safety. It is legitimate to ask how guidance is ensured.

The pleura is a thin membrane that lines the inside of the rib cage and surrounds the lungs. It lies just beneath the ribs. A breach of the pleura can let air in between it and the lung, causing a pneumothorax. To avoid this, surgeons work on the outer surface of the ribs, use selective instruments, control the depth and often rely on ultrasound. A small pneumothorax may resolve on its own; a larger pneumothorax sometimes requires drainage.

Each rib is accompanied along its lower edge by a nerve, an artery and a vein. Irritation of these nerves can cause band-like pain along the rib, or a numb area on the flank or abdomen. These problems are usually temporary but can sometimes persist. Surgeons avoid the nerve area, and local anaesthesia of the intercostal nerves during the procedure contributes to comfort after the operation.

After remodelling, a specific corset is worn for a prolonged period, often several weeks, day and night at first. It holds the ribs in their new position while the bone heals. Wearing it is demanding: it can restrict deep breathing, movement and sleep, and requires adjustment. Following this instruction determines part of the result. The corset is fitted and monitored by the team.

After remodelling, the rib bone repairs itself, as after a fracture, by forming a callus that solidifies the rib in its new position. This process takes several weeks, usually six to twelve, and then continues with slow remodelling of the bone over months. During this period, impacts and strenuous efforts involving the trunk must be avoided, and the corset must be worn as instructed. Good bone quality, not smoking and good nutritional status promote healing.

Rib remodelling acts only on the bone. In the vast majority of cases, fat is also present on the flanks, back and waist, and reducing it through liposuction contributes greatly to slimming. This is why the two procedures are often combined in the same operation, with the liposuction sometimes performed in high definition to sculpt the waist. This combination is described in detail on our dedicated page on RibXcar combined with full HD liposuction.

When rib remodelling is combined with high-definition waist liposuction, the procedure, how it is carried out, the recovery and the results have specific features, detailed on our dedicated page on RibXcar combined with full HD liposuction. This page focuses on understanding the ribs, non-surgical approaches and the principles of rib remodelling itself.

Liposuction combined with rib remodelling generally treats the flanks, lower back, sometimes the upper back and the abdomen, so that the waist is slimmed all the way round. The surgeon takes care to create a harmonious transition between the waist, hips and back, and to respect feminine or masculine curves. The fat removed can sometimes be reinjected into the hips or buttocks to enhance the curve, at the same time or later. These procedures require precise planning of the length of the operation.

For some people, the impression of a wide waist comes from a lack of curve at the hips rather than from excessive rib width. In this case, fat transfer to the hips or buttocks can enhance the contrast between the waist and the pelvis and give a more defined figure without touching the ribs. This better-known, less invasive option deserves to be discussed before any rib remodelling.

When several procedures are being considered, the order is open to discussion: rehabilitation first, then liposuction and possibly fat transfer, and only then, if the waist remains too wide because of the ribs, rib remodelling. Some teams combine liposuction and remodelling in the same session. Others prefer to separate the procedures to better judge the effect of each. The choice depends on the situation and the patient's preferences.

In some cases, the surgeon suggests performing waist liposuction first, then assessing the result before deciding on rib remodelling. This two-stage approach sometimes makes it possible to avoid rib surgery when liposuction is sufficient. It lengthens the process but reduces the risk of an unnecessary procedure.

Ultrasonic rib remodelling is a recent technique. The available data come mainly from the teams that developed or perform it, on limited patient series and with still short follow-up. They suggest a reduction in waist width of a few centimetres and high satisfaction among selected patients, with few serious complications reported. But several questions remain open: the long-term stability of the result, the effect on breathing and on the protection of the organs, the real frequency of complications in large series, and the consequences in the event of later chest trauma.

Teams interested in rib remodelling are seeking to select patients better, measure results more precisely, follow long-term outcomes and assess the effect on breathing and on organ protection. Larger studies, conducted by independent teams, are needed to confirm the initial results. Patients who agree to take part in follow-up contribute to this knowledge.

Given these uncertainties, most surgeons recommend great caution: reserving the technique for well-informed people whose flaring is genuinely bony, whose other waist components have been optimised, and who understand that they are committing to a procedure with limited follow-up data. A decision taken under the influence of spectacular images or a passing trend risks regret. Taking time, seeking several opinions and accepting the idea of giving up are all part of a responsible approach.

Rib remodelling raises ethical questions, like any aesthetic procedure on the skeleton with limited follow-up data. It involves altering a healthy structure, which protects organs and plays a role in breathing, for an aesthetic benefit. Medical societies and cautious surgeons stress the need for rigorous selection, complete information about the uncertainties, sufficient time for reflection, and patient follow-up to expand knowledge. The patient must be able to make a fully informed decision.

Some teams performing rib remodelling systematically collect their patients' data, with their consent, to follow results and complications over the long term. Taking part in this follow-up, by attending check-ups and answering questionnaires, helps to improve knowledge of a technique that is still recent. It is also a guarantee of follow-up for the patients themselves.

New surgical techniques are governed by the general rules of medical practice and medical devices. The instruments used must be authorised, and surgeons trained in their use. Professional societies gradually issue opinions and recommendations as data accumulate. This framework is evolving; it is useful to ask your surgeon about the current state of knowledge and recommendations.

The risks of rib remodelling include those of any procedure under general anaesthesia, as well as specific risks related to the proximity of the pleura, lungs, nerves and vessels.

Pain after rib remodelling is generally more marked than after liposuction alone, because the ribs move with every breath, every cough and every movement of the trunk. It is at its worst in the first few days, then gradually decreases over several weeks. Local anaesthesia of the intercostal nerves, appropriate painkillers and the corset help to control it. It is important to keep breathing deeply and coughing effectively despite the pain, to prevent lung complications.

In a minority of patients, pain may persist beyond a few months, linked to irritation of an intercostal nerve, slow healing or muscle tension. This prolonged pain is one of the most troublesome complications. It is managed with pain treatments, physiotherapy and sometimes injections. It should be reported without delay, as early management is more effective.

In the first few days, pain and the corset encourage shallow breathing, which risks poor ventilation of the lungs. Deep breathing exercises, taught by the team or a physiotherapist, and coughing while holding a cushion against the chest are recommended several times a day. Worsening breathlessness, sudden chest pain or a fever require prompt medical attention.

Rib remodelling surgery is only for a minority of people: those whose waist remains wide because of bony flaring of the lower ribs, despite a stable, low weight, reduced waist fat, toned abdominal muscles and corrected posture. They are most often young or middle-aged women in good health who want a more defined waist. Expectations must be realistic, and the person must accept the constraints of the corset and the long-term uncertainty.

Requests for rib remodelling come mainly from women seeking an hourglass figure, with a waist noticeably smaller than the bust and hips. For some, the waist remains wide despite considerable effort, because of the shape of the rib cage. After pregnancies, flaring may have developed; rehabilitation should then be tried first. Surgery is only considered afterwards, when the flaring persists and is bony.

In men, requests are rarer. The male ideal favours a V-shaped figure, with broad shoulders and a straight rather than very narrow waist. A protruding costal margin can nevertheless bother some very slim or very athletic men, particularly when lying down. Physiotherapy and abdominal strengthening are the first response. Rib surgery is only exceptionally offered to men. Our page on the male makeover presents male approaches to body contouring.

In men, a wide waist is most often due to fat, particularly inside the abdomen, rather than to the shape of the ribs. Very athletic men may have a protruding costal margin due to very chest-dominant breathing or unbalanced muscle development. Breathing rehabilitation and balanced training are the first response. Rib remodelling remains exceptional in men.

In some body feminisation journeys, the shape of the chest and waist is one of the concerns. Rib remodelling can sometimes be discussed in this context, with the same precautions and the same caution, as part of comprehensive care. Our page on body feminisation presents the different options.

Several situations make rib remodelling inadvisable: bone fragility or osteoporosis, active smoking, which impairs healing, lung disease, a history of pneumothorax, blood clotting disorders, a poorly controlled chronic illness, a pregnancy planned in the short term, a job or sport that exposes the chest to impacts, unrealistic expectations or disproportionate dissatisfaction with one's body. The surgeon looks for these situations during the assessment.

A stable weight close to your natural set weight is a prerequisite. Later weight loss would change the figure, and weight gain would mask the result. Most people considering rib remodelling are already slim; they should, however, be careful not to pursue excessive thinness, which would weaken the bone and recovery.

Some female athletes, particularly in disciplines where the back is often arched or breathing is heavily used, have a protruding costal margin. In these athletes, the postural and breathing component is often significant, and targeted work with a sports physiotherapist can improve the situation. Rib surgery, which requires a long break and rules out impacts during healing, is rarely compatible with elite-level sport.

Jobs involving carrying loads, repeated trunk movements or a risk of impact to the chest make recovery more difficult and can compromise healing. They require longer time off work and sometimes temporary adjustments to the workstation. It is useful to discuss this with the surgeon before deciding.

Healing of the ribs after remodelling depends on bone quality. People with vitamin D or calcium deficiencies, osteoporosis, hormonal disorders, past or present eating disorders, or who smoke, have less predictable healing. An assessment and, if necessary, correction of deficiencies precede any decision. A diet with sufficient protein, calcium and vitamin D supports healing.

Rib remodelling is generally offered to young or middle-aged adults who have finished growing and whose bone is of good quality. In older people, bone quality and the stiffness of the cartilage make the technique less suitable. In very young people, the maturity of the request must be carefully assessed, as this is an aesthetic procedure on the skeleton with limited follow-up data.

With age, the figure changes: fat shifts towards the waist and inside the abdomen, muscle mass decreases, posture changes and the costal cartilages stiffen. The waist tends to thicken, independently of the ribs. In older people, a widening waist is therefore rarely linked to rib flaring, and approaches to reduce fat, strengthen muscles and correct posture take priority.

At menopause, falling hormone levels promote the accumulation of fat at the waist and inside the abdomen, and weaken the bones. The waist often thickens, unrelated to the ribs. Regular physical activity, particularly strength training, an appropriate diet and looking after bone health take priority. Rib remodelling is rarely indicated at this stage, because of bone quality.

In young adults, the wish for a slimmer waist is sometimes influenced by social media and idealised images. Body shape may still change slightly, and the maturity of the request must be carefully assessed. Rehabilitation, physical activity and a balanced diet are the first responses. Surgery on the skeleton, with limited follow-up data, requires particularly careful reflection at this age.

The pursuit of a very small waist is sometimes fuelled by idealised images, edited or achieved by extreme means. When concern about the waist becomes overwhelming, or is accompanied by dietary restriction, risky practices or disproportionate dissatisfaction, a body image or eating disorder may be involved. Surgery on the skeleton offers no solution in this context. A responsible surgeon takes the time to talk about it and can refer to a professional.

A significant concern about the width of one's waist can affect self-image, choice of clothing and confidence. When this concern becomes overwhelming, takes up a lot of thought or is accompanied by risky behaviour, psychological support is helpful. It helps to restore a calmer relationship with one's body, whether or not one chooses to have a procedure.

A slimmer waist can improve self-confidence and comfort in one's clothes. But well-being depends on many other factors: health, fitness, relationships, self-image. An approach that combines physical activity, breathing, posture and, if necessary, a measured procedure often has positive effects beyond the figure, on energy and mood.

In some people, the pursuit of a very small waist may be part of a current or past eating disorder. This disorder weakens the bones and affects general health and body image. It requires specific care and makes rib surgery inappropriate until it has stabilised. An attentive surgeon raises this question tactfully.

The consultation begins with a discussion of expectations, weight history, pregnancies, sporting activity, diet and health. The surgeon examines the waist standing, from the front, side and back, in habitual and then corrected posture, on breathing in and breathing out. The surgeon palpates the costal margin and assesses the fat on the flanks and back, abdominal tone and the skin, and looks for any asymmetry or deformity of the chest. The surgeon then explains what is due to fat, posture and bone, and which options are suitable.

Results photographs presented by teams give an idea of what is possible, but they must be interpreted with caution: posture, breathing, lighting and time of day greatly alter the appearance of the waist. The most useful photos show patients with a comparable body shape, from several angles, at least six months to a year afterwards, with measurements. It is legitimate to ask for several examples, including less spectacular results.

Before any decision, it is useful to set concrete goals: reducing your waist measurement by a few centimetres, no longer seeing the costal margin protrude when lying down, wearing certain clothes better. These goals, discussed with the surgeon, make it possible to check that they are achievable and then to measure the result. A vague goal, such as a model's waist, leads to disappointment.

Imaging is often requested to assess the shape of the ribs, their orientation, their length and bone quality, and to plan any procedure. Depending on the team, this may be an X-ray, a CT scan or an ultrasound. A CT scan gives a precise three-dimensional view but involves radiation exposure, so its use is carefully weighed. Imaging also makes it possible to rule out a chest abnormality that would require different care.

Depending on the situation, several tests may be offered before a decision: rib imaging to clarify their shape, bone density measurement if bone quality is in doubt, lung function testing if there is a history of lung problems, and blood tests to look for deficiencies. These tests are not systematic; they are chosen according to each situation.

When imaging is performed, the surgeon can go through it with the patient: shape of the lower ribs, angle of opening, length of the floating ribs, symmetry, bone quality. This review helps to understand what can be changed and to what extent. It also helps to explain why the expected gain is limited to a few centimetres, and why some body shapes are not suitable.

There is no reliable simulation of the result of rib remodelling. The surgeon can give an estimate, based on imaging, measurements and experience, but the actual gain depends on the bone's response, the healing and the reduction of the associated fat. Digital simulations presented by some clinics should be taken as illustrations, not as promises.

Precise measurements are taken: waist circumference at the narrowest point, underbust circumference, chest width at the lower ribs, and hip circumference. Standardised photographs complement these measurements. They make it possible to compare before and after, but also to better understand the realistic gain: a few centimetres off the waist measurement can noticeably change the figure in some people, and much less in others.

To track progress, whether during rehabilitation or after surgery, it is useful to measure your waist regularly under the same conditions: in the morning, before eating, standing, after a normal breath out, with a tape measure placed horizontally at the narrowest point, then just below the bust and at the level of the lower ribs. Recording these measurements and taking a photo from the front and side, in the same lighting, allows progress to be measured objectively.

Before any surgery, many surgeons ask for a few months of breathing, abdominal and postural rehabilitation. If the flaring decreases significantly, surgery may become unnecessary. If the flaring persists despite serious rehabilitation, its bony nature is confirmed, and the indication can be discussed on a firmer basis. This step also has the advantage of strengthening the muscles that will support the result.

Even when surgery has been decided on, prior rehabilitation is useful: it strengthens the muscles that will support the result, improves breathing, which will be put to the test after the procedure, and prepares the patient for wearing the corset. People who come to the procedure with good control of their breathing and toned abdominal muscles often recover better.

Between clearly functional flaring and clearly bony flaring, there are many intermediate situations. The following table summarises the usual recommendations.

After rehabilitation or liposuction, the situation may have changed considerably: the flaring is less visible, the waist slimmer and the concern less significant. A reassessment a few months later makes it possible to decide whether rib remodelling is still useful. Many people then find that they are satisfied without rib surgery. This gradual approach is the most cautious.

The decision to undergo rib surgery requires careful reflection. It is based on an assessment confirming bony flaring, on the failure of a non-surgical approach, on a good understanding of the uncertainties, risks and constraints, and on realistic expectations. A reflection period of several weeks and a second opinion are strongly recommended. Deciding against surgery, after reflection, is often an equally legitimate decision.

The decision to have rib remodelling is made in several steps. The first is to understand what makes your waist wide. The second is to try non-surgical approaches. The third is to assess, with imaging, the bony component. The fourth is to receive complete information on the technique, its risks and its uncertainties, and to obtain a second opinion. The last is to take time to reflect, without pressure. Each step can lead to continuing or stopping.

Before any procedure, and even more so for a recent technique, the patient is entitled to clear and complete information: principle, expected benefits, limitations, risks, alternatives, uncertainties and the team's experience. This information is given orally and in writing, and the patient signs a consent form. Sufficient time between this information and the procedure allows the patient to reflect, ask further questions or decide against it.

Informed consent is more than a signature: it confirms that the patient has understood what is being proposed, including the uncertainties specific to a recent technique. It is useful to reread the document with a clear head, note down your questions and ask them before the procedure. Consent can be withdrawn at any time before the procedure.

It is sometimes wise to forgo rib remodelling: when the assessment shows that the width of the waist is mainly due to fat or posture, when contraindications exist, when expectations seem excessive, or simply when, after reflection, the constraints and uncertainties seem too great. Giving up is not a failure: many people find satisfaction in other, simpler approaches to their figure.

The GP knows the patient's medical history and can offer a useful perspective: history of lung problems, bone fragility, eating disorders, psychological health. They can help prepare for the procedure, correct deficiencies and handle part of the follow-up. Informing them of the plan also provides an outside opinion, which can be valuable in such a particular decision.

• Is my flaring bony or partly postural?
• Could rehabilitation be enough?
• How many centimetres can I reasonably expect?
• How many ribs would be treated, and how?
• How is the procedure guided to protect the pleura?
• How many patients have you operated on, and with what length of follow-up?
• What are the risks, and how often do they occur?
• How long will I have to wear the corset?
• What happens if the result is asymmetrical or insufficient?
• What do we know about the long-term result?

In consultation, the same questions often come up: how many centimetres can I gain, is it painful, how long do I wear the corset, is it dangerous for my lungs, how long does the result last, can I try something else first. The answers depend on each situation, but they often converge on the same messages: start by assessing and rehabilitating, keep expectations measured, understand the constraints and uncertainties, and take time to decide.

The journey, from the first consultation to the final result, often spans more than a year.

Preparation focuses on the bones, the lungs and organisation. It is recommended to stop smoking completely several weeks before and during healing, to correct any vitamin D or calcium deficiencies, to stabilise your weight, to practise breathing exercises and, if the team advises it, to get used to wearing the corset. Medications and supplements that promote bleeding should be reported. Hormonal contraception is discussed because of the risk of thrombosis. Finally, help at home and time off work need to be arranged.

Given the recovery and the corset, it is better to schedule the procedure at a quiet time, away from hot weather, major work deadlines and family events. Allow at least six to eight weeks of reduced activity, and several months before you can fully enjoy the result. The autumn and winter months are often chosen.

Rib remodelling is still a little-known procedure, which can provoke varied reactions from those around you, from curiosity to incomprehension. Everyone is free to decide whether or not to talk about it. Having at least one trusted person informed and available during the first few weeks is nevertheless important for practical help and moral support.

Before rib surgery, a full assessment is carried out: questions about lung, bone, hormonal and eating history, clinical examination, rib imaging, blood tests, and sometimes bone density measurement or lung function testing. The anaesthesia consultation assesses the risks associated with general anaesthesia and prepares pain management. This assessment ensures that the procedure can be carried out safely.

In some people, particularly in cases of asthma, a history of lung problems or doubt, lung function testing may be requested before the procedure. It measures lung volumes and airflow. It serves as a baseline and ensures that breathing will not be compromised by the procedure and the wearing of the corset.

When a risk of bone fragility is suspected, for example in the case of a history of eating disorders, hormonal disorders, long-term corticosteroid treatment or deficiencies, bone density measurement may be offered. Insufficient density makes remodelling inadvisable, as healing would be uncertain. Treating the bone fragility then becomes the priority.

Knowing in advance that pain after rib remodelling is significant and lasting helps you cope with it better. The team plans a strategy: local nerve anaesthesia, appropriate painkillers, positioning advice and breathing exercises. It is useful to have the prescribed medication at home, cushions, and someone available for the first few days. Pain that does not ease with the prescribed treatment should be reported.

Rib remodelling is performed under general anaesthesia. The anaesthetist often plans local anaesthesia of the intercostal nerves or the chest wall, guided by ultrasound, which significantly reduces pain on waking. Painkillers are then given at fixed times. Pain management is particularly important, as it determines the ability to breathe deeply and get moving.

After marking, positioning and anaesthesia, the patient is positioned so that the lower ribs are accessible, often on their side or front. The surgeon makes small incisions, locates the ribs, sometimes under ultrasound, and performs the remodelling. When liposuction is combined, it is performed in the same session. At the end of the procedure, the corset is fitted. An X-ray may be taken to check that there is no pneumothorax.

The patient arrives having fasted, after a thorough shower. The surgeon carries out the marking with the patient standing: locating the lower ribs, the costal margin, any liposuction areas and symmetry landmarks. Photographs are taken. The anaesthetist reviews the file and explains pain management. In the operating theatre, positioning is careful, particularly when changing position, with pressure points protected. At the end of the procedure, the corset is fitted before waking.

Rib remodelling alone generally takes one to two hours. Combined with waist liposuction, it can take two to four hours, or even longer with definition liposuction or fat transfer. Changes of position lengthen the procedure. The surgeon limits the total duration to reduce the risks associated with anaesthesia.

The scars from rib remodelling are small, from a few millimetres to one or two centimetres, placed on the flanks or back, often in areas covered by underwear. Those from the associated liposuction are also small. They fade over a few months. Sun protection during the first year limits their pigmentation.

The hospital stay usually lasts one to two nights, to monitor breathing, pain, the absence of pneumothorax and mobility. Discharge is decided when the pain is controlled by tablets, breathing is satisfactory and the patient can move around unaided.

On waking, the dominant sensation is rib pain, made worse by deep breathing and movement, and a chest held tight by the corset. The care team monitors breathing, oxygen saturation, pain and the appearance of the dressings. The first breathing exercises begin quickly. The first assisted time out of bed takes place the same evening or the next day.

Discharge is decided when the pain is controlled by tablets, breathing is satisfactory, the patient can get up and walk unaided and any follow-up imaging is reassuring. The team provides the prescriptions, instructions for wearing the corset, breathing exercises, the check-up schedule and a number that can be reached at any time. The journey home is made as a passenger, with a cushion to absorb vibrations during the journey.

In the first few weeks, bending, turning and carrying are difficult. It is useful to place everyday items within easy reach, to have a bed or armchair with an adjustable backrest, plenty of cushions, loose clothing that fits over the corset, meals prepared in advance, and someone present for at least the first week. For parents of young children, help is essential, as carrying a child is impossible for several weeks.

During the first few weeks after rib remodelling, many everyday actions are difficult: bending, carrying shopping, doing housework, getting up from a low bed. Help at home, from a relative or a professional, is essential for the first week and often useful for a month. For parents, help with the children is essential.

Car journeys can be painful in the first few weeks, because of vibrations and trunk movements. The seat belt must be worn, with a small cushion to cushion its pressure. Long journeys sitting down should be avoided in the first few weeks because of the risk of thrombosis and discomfort. Driving can resume when you can turn your upper body and brake without pain.

The first few weeks are marked by rib pain, made worse by coughing, laughing, sneezing and certain movements, breathing discomfort due to the corset, fatigue and, if liposuction was combined, bruising and swelling of the waist. The pain gradually decreases over several weeks. The corset is worn as instructed, often day and night at first.

Here is the most common course after rib remodelling combined with waist liposuction, to be adapted to each situation.

During the first few weeks, coughing, sneezing and laughing cause the ribs to move suddenly and provoke sharp pain. Holding a cushion against the chest, leaning slightly forwards and breathing out slowly before coughing help to ease this pain. However, you should not avoid coughing when it is necessary, as coughing helps to clear the lungs and prevents infections.

Fatigue after rib remodelling is often significant, linked to pain, sleep disrupted by the corset, limited breathing and the work of bone repair. It gradually decreases over several weeks. Naps, a protein-rich diet, good hydration and regular walks help you get through it. Fatigue that worsens or is accompanied by breathlessness requires a medical consultation.

Wearing the corset for a long time requires adjustment: loose clothing on top, a thin cotton undergarment underneath to protect the skin, regular checking of the skin for redness or irritation, and adjusting the tightness as instructed. Summer heat makes it more uncomfortable. The corset can make prolonged sitting and driving difficult. These constraints are temporary, but they need to be anticipated, particularly for work and travel.

To live comfortably with the corset, a few practical tips help: put it on and adjust it lying down, where the ribs are easier to hold in place, follow the tightening instructions precisely, check the condition of your skin every day, wear a thin undergarment underneath, have loose clothing to wear on top, and report any unusual pain or irritation. In summer, staying cool, keeping hydrated and changing the undergarment regularly improves comfort.

The corset is stopped according to the schedule set by the team, often gradually: first at night, then a few hours during the day, before stopping completely. This transition gives the muscles time to resume their supporting role. Removing it too early could compromise the position of the ribs. The rehabilitation that follows helps to strengthen the core muscles.

After stopping the corset, the feeling of lightness is often appreciated, but the trunk may feel less supported. Gradual rehabilitation strengthens the muscles and posture. Residual pain decreases and breathing regains its full range. The result on the waist becomes clearer, particularly once the swelling from the associated liposuction has gone. Measurements and photos at this stage make it possible to appreciate the change.

Prolonged contact with the corset can irritate the skin, particularly in areas of friction and around the incisions. Careful hygiene, thorough drying after washing, a thin undergarment and moisturising healthy skin limit this irritation. Persistent redness, a wound or localised pain should be reported, as the corset may need adjusting.

Bone healing requires sufficient protein, calcium and vitamin D. A varied diet, with dairy products or fortified alternatives, green vegetables, fish, eggs and pulses, contributes to this. Vitamin D supplementation is often advised, especially in winter. Alcohol and tobacco impair healing and should be avoided.

Recovery from rib remodelling is longer and more uncomfortable than from liposuction alone. Pain, the corset, fatigue and waiting for the result can weigh on your mood. Knowing in advance that this period will be demanding, surrounding yourself with support, keeping in regular contact with the team and setting small goals help you get through it. Persistent sadness is worth discussing with your doctor.

Contact the team promptly in the event of fever, warm redness spreading around an incision, cloudy discharge, pain that increases instead of decreasing, or an area of irritated skin under the corset. Worsening breathlessness, sudden chest pain, a cough with blood-stained sputum or a swollen, painful calf require you to call emergency services without delay.

For office work, people often return after two to three weeks, depending on pain and fatigue. Prolonged sitting with the corset can be uncomfortable. For physical work involving carrying loads or trunk movements, the time off is longer. Jobs exposing the chest to impacts require a specific discussion.

For office work, people often return after two to three weeks, sometimes earlier if working from home, depending on pain and fatigue. Sitting for long periods with the corset can be uncomfortable; regular breaks help. For physical work, several additional weeks off are needed, as carrying loads and trunk movements are limited during healing.

Walking is encouraged from the first few days. Gentle activities resume gradually depending on pain. Sports that place heavy demands on the trunk, chest and back strength training, and above all contact sports or those with a risk of falling are resumed late, after healing, on the surgeon's advice. Resuming too early could compromise the healing of the ribs.

Walking resumes from the first few days. Gentle activities, such as light exercise-bike work, resume after a few weeks depending on pain. Swimming resumes after the wounds have healed and on the surgeon's advice. Sports that place heavy demands on the trunk and strength training resume after bone healing, often after two to three months. Contact sports and those with a risk of falling are resumed last, with the surgeon's agreement.

Follow-up includes frequent check-ups in the first few weeks to monitor pain, breathing, wound healing and corset wear, then less frequent check-ups to assess bone healing and the result. Imaging may be carried out to check bone healing. These appointments are also an opportunity to adjust the corset and receive advice on resuming activities.

After the procedure, certain questions often come up: why does the pain last so long, when can I remove the corset, why does my waist still look wide, why does one side seem different from the other. The answers often relate to the timeline of bone healing and the resolution of swelling from the liposuction. Do not hesitate to ask these questions at check-ups.

After the initial phase, rehabilitation is often advised: full breathing despite the corset, then after its removal, trunk mobility, gradual strengthening of the abdominal and back muscles, and postural correction. It helps restore full breathing, prevent pain caused by compensations and support the result. A physiotherapist informed about the procedure adapts the exercises to the stage of bone healing.

In the first few weeks, sleeping on the treated side is painful. Lying on your back with your upper body slightly raised is often the most comfortable position. The corset can disturb sleep; follow the instructions for wearing it at night. Cushions help to find a bearable position.

Sleep can be disrupted by pain and the corset. A few tips help: sleep on your back with your upper body slightly raised on cushions, put a cushion under your knees to relax your back, avoid sleeping on the treated side for the first few weeks, and take the prescribed painkiller before bed if necessary. Naps make up for broken nights.

The corset is worn under loose clothing: shirts, tunics, loose dresses, trousers with soft waistbands. Clothes that open at the front avoid having to raise your arms and twist your trunk. A thin cotton undergarment under the corset protects the skin. Slip-on shoes avoid having to bend down.

A diet rich in protein, calcium and vitamin D supports bone healing and wound healing. Sufficient hydration helps reduce the swelling from the associated liposuction. Bowel movements, slowed by painkillers and reduced activity, can be helped by fibre and walking; since straining is painful, it is useful to prevent constipation.

The result combines the effect of rib remodelling, which reduces the width of the lower chest, and that of any liposuction. It becomes clearer as the swelling subsides and the ribs heal, over several months. Selected patients often describe a more defined waist from the front and back. The gain, of the order of a few centimetres on the waist measurement in published series, is variable and cannot be guaranteed.

Rib remodelling does not turn a straight figure into an extreme hourglass. It does not change the width of the pelvis or the overall shape of the chest. It does not compensate for significant fat. Its effect, when there is one, is of the order of a few centimetres. Setting measured expectations, based on photographs of comparable patients, is essential.

Ribs that have healed in their new position are expected to keep that shape. As follow-up is still limited, very long-term stability has not been established with certainty. Changes in weight and posture also influence the width of the waist over time. Maintaining a stable weight, good posture and toned abdominal muscles helps preserve the result.

After the corset is removed and the bone has healed, life gradually returns to normal. The pain usually disappears, breathing regains its full range, and sporting activities resume on the surgeon's advice, starting with low-impact sports. Some people retain tenderness or discomfort with certain movements for a few months. Contact sports are resumed last.

Revising rib remodelling is delicate, as it involves healed bone. When asymmetry or an insufficient gain is observed, it is sometimes possible to improve the figure with additional waist liposuction rather than a new procedure on the ribs. The surgeon discusses the options on a case-by-case basis, once the result has stabilised.

Slight asymmetry between the two sides is common, as the ribs are not always symmetrical to begin with and do not always heal in exactly the same way. Significant asymmetry can be bothersome. It is difficult to correct at bone level; targeted liposuction can sometimes reduce it. The surgeon informs the patient of this before the procedure.

In the long term, maintaining the result depends on the stability of the healed ribs, weight, posture and musculature. Natural ageing also changes the figure. Very long-term data are still lacking; regular follow-up and participation in studies will provide a better understanding of how results evolve. In the meantime, a stable weight, regular physical activity and good posture are the result's best allies.

Once the journey is complete, many patients describe feeling more at ease in their clothes and having a figure more in line with their wishes. The postural and breathing work learned during rehabilitation remains useful in everyday life. The only lasting precautions are to inform healthcare professionals of the past procedure in the event of a chest problem, and to keep physically fit.

During pregnancy, the rib cage widens to make room for breathing. After rib remodelling, pregnancy remains possible, but it could partly alter the result, and the effect of remodelling on this adaptation of the rib cage is poorly documented. It is recommended to discuss pregnancy plans with the surgeon before the procedure, and preferably to consider remodelling once family plans are complete.

One question that has been little studied concerns how remodelled ribs behave in the event of later chest trauma, for example in an accident or a fall. Once healed, the ribs are expected to regain near-normal strength. It is nevertheless useful to inform healthcare professionals of the past procedure in the event of chest trauma, so that they can take it into account in their assessment.

Regrets after rib surgery, when they occur, concern pain lasting longer than expected, a gain below expectations, asymmetry, or the feeling of having acted under the influence of a trend. They underline the importance of rigorous selection, complete information and sufficient time for reflection.

The most satisfied patients are those whose flaring was genuinely bony, who had measured expectations, who fully understood the constraints and uncertainties, and who were supported throughout the journey. They appreciate a more defined waist, often combined with the effect of liposuction. Disappointments come mainly from excessive expectations, prolonged pain or a gain considered insufficient.

Patients who have had rib remodelling often mention a more difficult recovery than they had imagined, because of the pain and the corset, but say they are satisfied when the gain achieved matches their expectations. Those who first underwent rehabilitation often stress that it helped them understand their body better, and sometimes to decide against surgery. Many advise taking your time, seeking several opinions and being wary of images that look too perfect.

These accounts bring together frequently encountered situations; they do not describe real patients.

Laetitia, 31, rehabilitation was enough

Laetitia came for a consultation about a waist she considered wide despite a low weight. The examination showed a protruding costal margin that clearly flattened when she breathed out and corrected her arched back. The surgeon advised breathing and abdominal rehabilitation. After four months of regular work with a physiotherapist, her waist measurement had decreased and the costal margin was much less visible. She decided against surgery.

Svenja, 35, an indication for surgery

Svenja had always had a wide chest at the level of the lower ribs. Slim and athletic, she had undergone rehabilitation without any notable change. Imaging confirmed bony flaring. After two consultations and a second opinion, she chose lower-rib remodelling combined with liposuction of the flanks. The pain in the first few weeks was significant, and the corset restrictive. At one year, her waist measurement had decreased by a few centimetres, and she said she was satisfied, while acknowledging that the recovery had been more difficult than she had imagined.

Mathilde, 27, a deferred request

Mathilde wanted a very small waist, inspired by images she had seen online. The examination showed moderate fat and an arched posture, without marked bony flaring. The surgeon discussed her expectations and her relationship with her body, and suggested starting with rehabilitation and follow-up, without rib surgery. A few months later, she chose limited waist liposuction.

Flaring after three pregnancies

A forty-year-old woman comes in about a chest she has found wide since her third pregnancy, with a bulging abdomen. The examination shows separated abdominal muscles, excess skin below the navel and a flared costal margin that draws in clearly on breathing out. The surgeon explains that the main problem is the abdominal wall. He suggests rehabilitation, then a tummy tuck with muscle repair. After the procedure, the costal margin is less prominent and the waist more defined, without any procedure on the ribs.

A man bothered by his ribs

A twenty-eight-year-old man, very slim and athletic, is bothered by lower ribs that protrude when he lies down. The examination shows a pronounced arch in the back and very chest-dominant breathing. The surgeon refers him to a physiotherapist. After a few months of breathing and postural work, the protrusion is less visible and the concern has disappeared.

In Switzerland, ultrasonic rib remodelling is offered by a limited number of teams, mainly in the large cities, as it requires specific equipment and training. Breathing and postural physiotherapy, on the other hand, is available everywhere. Price differences between regions are expressed as a percentage relative to Geneva, for comparable rib remodelling, with or without combined liposuction.

As rib remodelling is only offered in a few cities, many patients have to travel. It is then important to organise follow-up: stay nearby for the first few days, plan the check-ups, know who to contact locally in the event of a breathing problem or severe pain, and find a physiotherapist near home for rehabilitation. The GP can take over part of the care.

Rib remodelling represents a significant cost, linked to the equipment, the team's training, the length of the procedure, the hospital stay, the corset and follow-up. It is generally combined with liposuction, which increases the overall budget. Our page on rib remodelling prices in Switzerland details these elements. Physiotherapy, on the other hand, represents a modest cost and may be covered on prescription, depending on the conditions.

The quote should specify the number of ribs treated, the technique, the combined liposuction and its areas, anaesthesia, the hospital stay, the corset, imaging, check-ups and any physiotherapy. It is useful to know what is provided in the event of a complication, such as a pneumothorax requiring treatment, or in the event of an asymmetrical result.

Beyond the quote for the procedure, you need to anticipate imaging, rehabilitation before and after, the corset if it is not included, physiotherapy sessions, time off work, help at home and possibly pain treatments or additional liposuction. An overall budget drawn up in advance avoids unpleasant surprises.

Comparing several quotes helps to understand price differences. The comparison should cover the same package: number of ribs treated, combined liposuction, anaesthesia, hospital stay, corset, imaging and follow-up. A significantly lower price may correspond to less comprehensive care. For a recent technique, the team's experience is a more important criterion than price.

Aesthetic rib remodelling is not covered by compulsory health insurance. Physiotherapy, when prescribed for a medical reason, may be covered depending on the applicable conditions. Chest deformities requiring specific medical care follow other rules. It is wise to find out about coverage for any complication.

For such a recent technique, the team's experience is decisive. The specialist title in plastic, reconstructive and aesthetic surgery, verifiable in the official register of medical professions, is a prerequisite. It is useful to know how many rib remodelling procedures the team has performed, with what length of follow-up, how it selects patients, how it guides the procedure and manages complications, and whether it works with thoracic surgeons or physiotherapists. A team that offers rehabilitation first and is willing to say no is a good sign.

For a recent technique, it is reassuring to consult a surgeon who takes the time to assess posture and fat, offers non-surgical approaches first, explains the uncertainties without minimising them, shows a range of results, is willing to say no and encourages a second opinion. Conversely, a quick proposal without a thorough assessment, with promises of spectacular results, should prompt caution.

Information about rib remodelling available online varies greatly in quality. Testimonials can be useful, but they do not always reflect the reality of each situation. It is better to rely on information provided by qualified surgeons, physiotherapists and, as they develop, scientific publications and recommendations from medical societies.

A second opinion is particularly recommended before rib surgery, because the technique is recent and there are uncertainties. Another surgeon, or even a specialised physiotherapist, can confirm the nature of the flaring, suggest another approach or advise waiting. Comparing opinions allows for a more confident decision.

For a procedure on the skeleton with limited follow-up data, a reflection period of several weeks, or even several months, is recommended. This time allows you to try rehabilitation, obtain a second opinion, reread the written information and check that the wish is lasting. A decision taken in a hurry or under the influence of a trend is more likely to lead to regret.

Support from those around you matters at every stage: to accompany the reflection process, to help during recovery, and to encourage regular practice of the rehabilitation exercises. Sharing your plan with a trusted person also provides an outside view of your motivation and expectations.

It is useful to keep all documents relating to the journey: consultation reports, imaging, the rehabilitation programme, measurements and photos, the operative report and follow-up instructions. These documents will be valuable for follow-up, for a second opinion, and in the event of a later consultation for a chest problem, so that healthcare professionals can be informed of the past procedure.

• My flaring has been assessed and is mainly bony.
• I have undergone breathing, abdominal and postural rehabilitation.
• My weight is stable and my waist fat has been reduced or assessed.
• I have stopped smoking and corrected any deficiencies.
• I understand that the technique is recent and that follow-up data are limited.
• I know the risks, including pneumothorax and prolonged pain.
• I am ready to wear the corset for several weeks.
• I have realistic expectations, of the order of a few centimetres.
• I have obtained a second opinion.
• I have taken time to think it over.

The width of the waist depends on fat, posture, breathing and the skeleton. Flared ribs may have a functional origin, often improvable through rehabilitation, or a bony one. Surgical rib remodelling is a recent technique, reserved for selected cases, which requires a demanding recovery and has limited follow-up data. It is often combined with liposuction. Caution, information and patience are the watchwords of any approach.

A wide waist is not just about the ribs. Before considering a procedure on the skeleton, it is essential to assess the contribution of fat, posture and breathing, which can often be improved by simple, risk-free means. When the flaring is genuinely bony and the concern persists, rib remodelling can be discussed, with an understanding of its constraints and uncertainties. Taking time, getting informed, seeking several opinions and being willing to give up are the keys to a successful decision.

A responsible approach to a waist considered too wide consists of first understanding your body, trying simple, risk-free approaches, getting information from qualified professionals, comparing opinions, and considering a procedure on the skeleton only as a last resort, with realistic expectations. This approach protects your health and increases the chances of being satisfied with the result, whichever option is finally chosen.

Before any decision, start by observing your posture and breathing, and try a few months of rehabilitation with a professional. If necessary, reduce the fat around your waist. Then consult a cautious plastic surgeon, who will assess the bony component of your flaring. If surgery is proposed, ask for a second opinion, find out about the uncertainties and take time to think. This gradual approach is the safest and most satisfying.

If your waist concerns you, a consultation with a cautious plastic surgeon, combined with a physiotherapist's opinion, will help you understand what makes your waist wide and which options are suitable. In most cases, the answer does not involve the ribs. When it does, careful support at every stage is essential.

If you are wondering about the width of your waist, know that you are not alone, and that many solutions exist, most of them simple and risk-free. Take the time to understand your body with a professional, try rehabilitation and, if you are considering surgery, get fully informed. A decision taken calmly is the best guarantee of satisfaction.

The width of the waist depends on fat, musculature and posture, and on the skeleton. When the lower ribs are flared, it is first necessary to distinguish functional flaring, linked to posture and breathing, which often improves with physiotherapy, from bony flaring. In the latter case, recent surgical techniques, such as ultrasonic remodelling, can reduce the width of the lower chest by a few centimetres, at the cost of a demanding recovery with a corset, and long-term uncertainties. They are often combined with waist liposuction.

In Switzerland, physiotherapy is available everywhere, whereas surgical rib remodelling is offered by a few teams, mainly in the large cities. Our guide to aesthetic body surgery presents all the options for body contouring.

Flared ribs, physiotherapy, surgery, corset, recovery, risks, results and price: answers to frequently asked questions.

Understanding

What is rib remodelling? All the approaches aimed at reducing the width of the lower chest when the lower ribs are flared.

What are flared ribs? Lower ribs angled outwards, which widen the chest just above the waist.

What is RibXcar? A recent technique that reshapes the curvature of a few lower ribs through small incisions and ultrasound.

Which ribs are involved? Mainly the lower ribs, from the tenth to the twelfth.

What are floating ribs? The eleventh and twelfth ribs, which are not attached to the sternum.

Does the width of the waist depend only on the ribs? No, fat, musculature, posture and the pelvis also play a role.

Can the pelvis be altered? No, its width cannot be changed.

Functional flaring

Can flaring come from posture? Yes, a pronounced arch in the back makes the costal margin stick out.

Does breathing play a role? Yes, high chest breathing and a poorly mobile diaphragm keep the ribs in a flared position.

How can I tell if my flaring is functional? If it decreases significantly when you breathe out hard and correct your posture, it is partly functional.

Can physiotherapy help? Yes, breathing, abdominal and postural rehabilitation often reduces functional flaring.

How long does rehabilitation take? Several months of regular practice.

Which exercises are useful? Diaphragmatic breathing, prolonged exhalation, strengthening of the transverse abdominis and obliques, correction of the arched back.

Is Pilates useful? Yes, it works on breathing, the deep muscles and posture.

Do waist trainers slim the waist? Their effect is temporary and they carry health risks.

After a pregnancy

Can pregnancy flare the ribs? Yes, the rib cage widens during pregnancy and may not fully return to its shape.

What should I do after a pregnancy? Start with abdominal and breathing rehabilitation.

Is surgery possible after pregnancies? It may be considered if the flaring persists and is bony.

Surgery

When is surgery considered? When the flaring is bony, persists despite rehabilitation and is very bothersome.

What does ultrasonic remodelling involve? Making a few ribs more flexible through small partial breaks, then holding them inwards with a corset.

Are ribs removed? Current techniques reshape the curvature; floating rib resection is rarely offered today.

How many ribs are treated? Usually a few lower ribs on each side.

Is the procedure guided? Often by ultrasound, to protect the pleura and neighbouring structures.

What type of anaesthesia? General anaesthesia, often supplemented by local anaesthesia of the intercostal nerves.

How long in the clinic? Usually one to two nights.

Why combine with liposuction? Because waist fat also contributes to its width.

Are the incisions large? No, they are small.

Corset

Why wear a corset after surgery? To hold the ribs in their new position while they heal.

How long is the corset worn? Several weeks, according to the team's instructions.

Does the corset restrict breathing? It can limit deep breathing; breathing exercises are recommended.

Can the corset be removed for sleeping? Follow the instructions; it is often worn day and night at first.

Is the medical corset a waist trainer? No, it has a precise, temporary medical purpose and is worn under supervision.

Recovery

Is the pain severe? It is more marked than after liposuction, especially when coughing and moving, and decreases over several weeks.

How should I breathe after the procedure? By doing deep breathing exercises several times a day.

How can I cough without too much pain? By holding a cushion against the chest.

When can you return to work? Often after two to three weeks for office work.

When can I return to sport? Gradually; contact sports must wait until the bone has fully healed.

How should I sleep? On your back, with your upper body slightly raised, for the first few weeks.

Can I drive? After a few weeks, when trunk movements are possible without significant pain.

Risks

What are the main risks? Pneumothorax, prolonged pain, intercostal nerve damage, bleeding, failure of bone healing, asymmetry.

What is a pneumothorax? The presence of air between the pleura and the lung, which can impair breathing.

Which signs should raise concern? Worsening breathlessness, sudden chest pain, fever.

Can the pain last a long time? It can persist for several weeks, and longer in some patients.

Do the ribs protect the organs less afterwards? This question has been little studied in the long term.

Results

How many centimetres can be gained? Published series report a few centimetres, with variation.

Is the result guaranteed? No.

Is the result lasting? It is expected to be once the ribs have healed, but follow-up data are limited.

When is the result visible? It becomes clearer over several months.

Can an extreme hourglass be achieved? No, the gain remains moderate.

Who it suits

Who might surgery be considered for? Slim people in good health, with confirmed bony flaring and realistic expectations.

Can men benefit from it? It is rare; physiotherapy is the first response.

Is there an age limit? The technique mainly concerns young to middle-aged adults with good-quality bone.

Is osteoporosis a contraindication? Yes, bone fragility makes it inadvisable.

Is smoking a problem? Yes, it impairs bone healing.

Is lung disease a contraindication? It requires a thorough assessment and often makes the technique inadvisable.

Anatomy and breathing

How do the ribs move when breathing? They rise and spread apart on breathing in, and lower and draw together on breathing out.

What is the role of the diaphragm? It is the main breathing muscle; it attaches to the inner surface of the lower ribs.

Do the oblique muscles influence the ribs? Yes, they lower and draw in the costal margin.

Does the transverse abdominis play a role? Yes, it acts like a belt that holds in the waist.

Can scoliosis cause a protruding rib? Yes, on one side; it requires an orthopaedic assessment.

What is funnel chest? A sunken sternum, often associated with protruding lower ribs, which requires medical care.

Can flaring be asymmetrical? Yes, particularly when it is constitutional or linked to scoliosis.

Rehabilitation in practice

Which professional should I see for rehabilitation? A physiotherapist trained in breathing, abdominal and postural rehabilitation.

How many sessions are needed? A few learning sessions, then regular practice at home for several months.

Should the exercises be continued afterwards? Yes, to maintain the progress made.

Is yoga useful? It helps work on breathing and posture.

Can strength training worsen flaring? Unbalanced training, without the deep muscles, can accentuate it.

Is swimming beneficial? It promotes good breathing and balanced strengthening.

Can progress in rehabilitation be measured? Yes, with waist and chest measurements and photographs.

Frequently asked questions

Can the waist be slimmed without surgery? Often partly, by reducing fat, strengthening the abdominals and correcting posture.

Is liposuction sometimes enough? Yes, when the width is mainly due to fat.

Does rib remodelling make you lose weight? No, it acts on the shape of the skeleton.

Is the technique recognised? It is recent and performed by a limited number of teams.

Are there independent studies? There are still few of them.

Can a diet reduce flaring? No, but it can reduce the fat around it.

Does social media give an accurate picture? Not always; images are often idealised or edited.

Can just one side be treated? Sometimes, in cases of marked asymmetry.

Can I get pregnant after rib remodelling? Nothing prevents it, but the rib cage widens during pregnancy; it is better to discuss it beforehand.

Does the technique change the voice or breathing at rest? No effect is expected at rest, but the long-term effect on breathing has been little studied.

Preparation

Is imaging needed beforehand? Often, an X-ray, CT scan or ultrasound depending on the team.

Should a vitamin D deficiency be corrected? Yes, to promote bone healing.

Should I get used to the corset beforehand? Some teams advise it.

Should hormonal contraception be stopped? It is discussed because of the risk of thrombosis.

Is help at home needed? Yes, for the first few weeks.

How can I prepare my breathing? With regular breathing exercises before the procedure.

After the procedure

Is an X-ray needed after the procedure? Some teams take one to check that there is no pneumothorax.

When can the corset be removed? According to the instructions, after several weeks.

Is physiotherapy useful afterwards? Yes, for breathing, posture and strengthening.

Can I wear a bra? According to the instructions, avoiding bands that press on the treated areas.

When can back strength training resume? After bone healing, on the surgeon's advice.

Is a follow-up imaging check planned? Sometimes, to check bone healing.

Are the scars visible? They are small and fade.

Can I go back to running quickly? No, high-impact sports must wait until the bone has healed.

Does rib remodelling leave lasting breathing problems? None are expected in selected patients, but follow-up data remain limited.

Is it reimbursed? No, it is an aesthetic procedure.

Is physiotherapy reimbursed? On medical prescription, depending on the applicable conditions.

Where is the technique offered? By a few teams, mainly in the large cities.

How do I choose a team? Specialist in plastic surgery, experience with the technique, rigorous selection, cautious approach.

Is a second opinion needed? Yes, it is strongly recommended.
