The human rib cage is a vital structure, protecting the delicate organs within the thoracic cavity and supporting respiratory functions. In most cases, the ribcage appears symmetrical. Still, it may be asymmetrical for some individuals due to various factors, leading to an uneven rib cage.

While this condition is not problematic, it can have potential complications that warrant attention and understanding. This article explains uneven ribcages and explores the possible causes, associated health risks, and available management strategies.

What is a rib cage?

The rib cage is formed by the ribs attached to the thoracic vertebrae in the back and the sternum in the front by cartilage. The top seven pairs of ribs are connected directly to the sternum. The following three pairs are attached via cartilage, while the last two pairs are known as “floating ribs” because they are not connected.

Understanding the Uneven Rib Cage

An uneven rib cage refers to a condition where one side of the ribcage protrudes or appears more extensive than the other, leading to an asymmetrical appearance. It may affect one or more ribs, and the severity can vary among individuals.

The condition can be present from birth (congenital) or develop over time due to various factors. Uneven ribcages can be attributed to several causes, and understanding them is crucial in comprehending their potential complications.

Symptoms of Uneven Rib Cage

This deformity affects the natural alignment of the ribcage and can lead to various symptoms and discomfort. It is essential to recognize the signs of rib flare to seek appropriate medical attention and understand any potential underlying conditions contributing to the problem.

Visible Rib Protrusion: The primary symptom of rib flare is the noticeable outward protrusion of the lower ribs. This is particularly visible when standing upright and can be more pronounced in individuals with a lean body structure.

Rib and Chest Pain: Rib flare may cause pain or discomfort in the affected area. The misalignment of the ribs can strain the surrounding muscles, ligaments, and soft tissues, leading to localized pain.

Back Pain: The altered ribcage alignment can affect the spine’s position, potentially leading to back pain. The lower back is especially susceptible to strain as it tries to compensate for the rib flare.

Postural Changes: Individuals with rib flare may experience changes in their posture. The condition can cause the shoulders to round forward and the upper back to hunch, leading to a more pronounced hump in the back.

Restricted Breathing: In severe cases, rib flare can interfere with lung expansion during breathing. This can lead to reduced lung capacity and may cause feelings of breathlessness, especially during physical activities.

Abdominal Discomfort: Rib flare can also pressure the abdominal region, leading to discomfort and sometimes digestive issues.

Tenderness to Touch: The area around the protruding ribs may become tender to touch due to the increased strain on the surrounding tissues.

Causes of Uneven Rib cage

1) Injury and Trauma

Accidents or injuries to the chest area can lead to misaligned or dislocated ribs, resulting in an uneven rib cage.

Blunt force trauma: When the chest or rib cage is struck, as can happen in a car accident or during a sporting event, the bones may shift or realign.

Fractures: One or more fractured ribs can cause the rib cage to become uneven because the ribs may mend in a slightly different position than before the accident.

Surgery: Certain surgical operations, such as those that involve the chest or rib cage, might make the cell appear uneven.


If your injury was recent, consult a medical specialist to assess your rib injuries and promote symmetrical healing.

2) Birth Defects

Some individuals are born with an uneven ribcage due to developmental abnormalities during fetal growth. These anomalies may involve the ribs, sternum, or spine, leading to asymmetry within the ribcage.

Congenital scoliosis: This type of scoliosis, present from birth, is brought on by faulty cage of ribs and spine development.


Depending on the severity of the disease and the patient’s general health, there may be several treatment options for birth abnormalities that result in an uneven rib cage. Surgery may only sometimes be needed to address the underlying problem, even though it is necessary in some cases.

3) Rib Cartilage Deformities

Pectus excavatum: Pectus excavatum is a condition where the sternum, or breastbone, is recessed, giving the chest a concave appearance. The rib cage may appear unequal as a result of this.

Pectus carinatum: Pectus carinatum causes the breastbone to protrude outward, making the chest appear larger. Moreover, the cage of the rib may appear uneven as a result of this.


The best course of treatment for rib abnormalities typically relies on the patient’s unique situation, age, general health, and other considerations. A medical expert can assess the severity of the deformity and suggest the best line of action for therapy.

4) Muscle Weakness

Imbalances in the muscles supporting the ribcage can cause one side to be more prominent. Poor posture, lack of exercise, or repetitive strain on one side of the body may contribute to muscle imbalances. Some factors that can contribute to chest or back muscle weakness include.

Inactivity: If the muscles in the chest or back are not used or exercised regularly, they can weaken or atrophy over time.

Poor posture: such as slouching or hunching over, can place undue strain on specific muscles, causing them to weaken or become imbalanced.

Injury: A sprain or strain to the chest or back, for example, can cause the muscles in the affected area to weaken.

Neurological conditions: such as multiple sclerosis and muscular dystrophy, can cause muscle weakness throughout the body, including the chest and back.

Age: Our muscles naturally weaken and become less flexible as we age, which can contribute to an uneven rib cage.


Physical therapy or targeted exercises can strengthen weak muscles and improve an uneven rib cage. Braces and other supportive devices may also align the cage better. It’s crucial to consult a medical expert on the best course of action for treating an uneven cage rib brought on by muscle weakness.

5) Scociliosis

Scoliosis is a spinal condition characterized by abnormal lateral curvature, often causing one side of the ribcage to protrude more prominently. This curvature can create an uneven appearance and impact lung function.

Many factors, including heredity, neuromuscular disorders, and other causes, might contribute to scoliosis. Together with adults, children and teenagers can also experience it.


Depending on the severity of the problem and the patient’s age, there are many scoliosis treatment methods. In minor cases, it may be sufficient to observe the spine’s curvature over time.

Health Complications

Respiratory Problems: An uneven rib cage can affect the expansion of the lungs during breathing, leading to decreased lung capacity and potentially causing respiratory difficulties. Reduced lung function may result in shortness of breath, especially during physical activities.

Cardiovascular Impact: An uneven rib cage can pressure the heart and blood vessels in severe cases, potentially affecting cardiovascular function. Such pressure may impede proper blood circulation and increase the risk of cardiovascular conditions.

Emotional and Psychological Effects: Individuals with an uneven rib cage might experience emotional distress due to body image concerns and self-esteem issues. This could lead to social anxiety and reduced quality of life.

Musculoskeletal Strain: The uneven distribution of weight and pressure on the ribs can cause strain on the muscles and connective tissues surrounding the ribcage, leading to discomfort and pain.

Associated Conditions with Uneven Rib Cage

Rib flare can be a symptom of underlying conditions that affect the structure and alignment of the ribcage and spine. Some associated conditions include:

Scheuermann’s Disease: This type of juvenile osteochondrosis affects the spine, leading to abnormal curvature and possible rib flare.

Marfan syndrome: This genetic disorder affects connective tissues, potentially leading to rib deformities and other skeletal abnormalities.

Thoracic Outlet Syndrome: Uneven ribcage can sometimes be associated with thoracic outlet syndrome, characterized by compression of nerves and blood vessels between the first rib and clavicle.

7) Supportive Devices

In some cases, a specially designed brace or orthotic may be recommended to support and reduce pain for individuals with scoliosis or severe asymmetry.

8) Heat and Cold Therapy

Applying heat or cold packs to the affected areas can temporarily relieve muscle soreness and discomfort.

9) Mind-Body Techniques

Yoga, tai chi, and meditation can help reduce stress and promote relaxation, potentially easing muscle tension and discomfort.

Exercises for an uneven rib cage

Your doctor or physician may recommend workouts to help your muscles retain your ribs cage in place if cases of slightly unequal ribs happen to occur.

Breathing can be made easier and your rib cage can be more aligned by strengthening your back and abdominal muscles. More exercise repetitions on your weaker side can assist you develop a more even appearance if your uneven side is weaker.

1) Diaphragmatic Breathing

Diaphragmatic breathing, also known as deep belly breathing, can improve respiratory function and promote relaxation. Lie on your back with your knees bent, placing one hand on your chest and the other on your abdomen. Inhale deeply through your nose, allowing your stomach to rise as you fill your lungs with air. Exhale slowly through your mouth, feeling your stomach fall. Repeat for several breaths.

2) Cat-Cow Stretch

This yoga-inspired exercise helps mobilize the spine and improves posture. Start on your hands and knees in a tabletop position. Inhale, arch your back and lift your head and tailbone to create a “cow” shape. Exhale, round your back, tuck your chin and draw your belly button towards your spine to create a “cat” shape. Repeat the sequence for 8-10 repetitions.

3) Side Stretch

The side stretch targets the intercostal muscles between the ribs, helping to improve ribcage alignment. Stand with feet hip-width apart, raise one arm overhead, and lean gently to the opposite side. Hold the stretch for 20-30 seconds, then switch to the other side.

4) Chest Opener Stretch

This stretch helps to open the chest and improve posture. Stand or sit tall with shoulders relaxed. Clasp your hands behind your back and lift your arms slightly. Gently squeeze your shoulder blades together and lift your chest. Hold for 20-30 seconds.

5) Wall Angels

Wall angels are a corrective exercise to improve shoulder and thoracic mobility. Stand with your back against a wall, elbows bent at 90 degrees, and forearms against the wall. Slide your arms up the wall while keeping your back and elbows in contact. Lower your arms back down. Repeat for 10-15 repetitions.

6) Thoracic Extension Exercise

This exercise helps improve thoracic mobility and ribcage alignment. Lie on your back with a foam roller placed horizontally under your upper back. Support your head with your hands and gently arch your upper back over the foam roller. Hold for a few seconds and then return to the starting position. Repeat for 8-10 repetitions.

Seek Emotional Support

Living with an uneven ribcage can be emotionally challenging, especially for those facing body image concerns. If needed, it is essential to foster self-acceptance and seek emotional support from friends, family, or mental health professionals. Supporting groups or online communities can also provide a sense of belonging and understanding.


You may know if your rib cage is out of alignment if you observe visible protrusion or unevenness of the ribs, experience localized pain or discomfort in the chest or back, have difficulty breathing deeply, or notice changes in your posture, such as rounding of the shoulders and hunching of the upper back.

Yes, a chiropractor can help with an uneven ribcage. They may use gentle manipulation techniques to realign the rib and surrounding structures, reducing pain and discomfort. However, it’s essential to seek a proper diagnosis from a healthcare professional to ensure the safety and appropriateness of chiropractic treatment for the specific condition.

Rib distortion refers to an abnormality in the shape or alignment of one or more ribs. It can result from various factors, including injury, trauma, congenital anomalies, or underlying conditions like scoliosis. Rib distortion may cause visible changes in the ribcage’s appearance, lead to pain and discomfort, and affect breathing and posture. Proper diagnosis and treatment are essential to manage rib distortion and address any underlying issues contributing to the deformity.

No, rib distortion and rib flare are not the same. Rib distortion refers to an abnormality in the shape or alignment of the ribs, which can result from various causes. Rib flare refers explicitly to the outward protrusion of the lower ribs, causing them to stick out prominently, usually due to poor posture or other factors.

Dysfunctional rib syndrome is when the ribs become restricted or fixated, causing pain and discomfort. It is not the same as rib flare. Rib flare refers explicitly to the outward protrusion of the lower ribs. In contrast, dysfunctional rib syndrome involves restrictions or misalignments of the ribs, leading to localized pain and restricted movement.

The Bottom Line

An uneven ribcage, though not uncommon, can have potential complications and health implications that warrant attention. Understanding the underlying causes and seeking appropriate medical evaluation and treatment can help manage associated symptoms and improve overall well-being.

Moreover, embracing self-acceptance and seeking emotional support can be vital in navigating the challenges of living with an uneven ribcage. Awareness of this condition and its potential effects is essential for promoting early intervention and bettering the lives of those affected.
