Rib flaring or flared ribs—when the lower ribs protrude outward instead of resting naturally against the torso. This comprehensive guide explains every available option in straightforward, patient-friendly language.
Rib flaring occurs when the costal margins (the lower edges of the rib cage) tilt outward or upward more than usual. It can occur:
Although rib flare is not medically dangerous, it may contribute to:

Understanding the root cause is essential because treatment varies depending on whether the chest deformity is functional (muscular imbalance, muscle tension, postural issues) or structural (bone/cartilage-related).
The underlying cause determines whether non-surgical treatment, bracing, or surgery is appropriate.
One of the most common causes of rib flare is Poor posture—especially excessive lumbar extension (arching of the lower back)—which tilts the rib cage forward, pushing the ribs outward.
Common postural contributors include:
When the diaphragm is underused, and chest breathing dominates, the lower rib cage lifts excessively during inhalation, elevates and rotates the lower ribs outward, and results in ineffective breathing.
Rib flare is often associated with weak or poorly coordinated:
These core muscles typically stabilise the rib cage during breathing and movement.
In some patients, rib flare is part of a congenital or structural chest wall difference, such as:
In teenagers, rib flare often becomes noticeable during rapid growth. Past rib trauma or fractures may also lead to long-term asymmetry.
For most people, especially those with posture-related or muscular rib flare, non-surgical rib-flaring treatment is the first and most successful approach.
The diaphragm is the primary muscle responsible for correct rib cage mechanics. Proper diaphragm activation helps “pull down” the rib cage and restore alignment.
Patients learn:
Weak internal obliques allow the rib cage to flare outward. Specific exercises help stabilise the ribs and pelvis.
Common exercises include:
Physical therapists correct:
Non-surgical therapy is also recommended before surgery to improve outcomes.
Rib flare bracing is less common than bracing for pectus carinatum, but it can be beneficial for adolescents with flexible cartilage.
Bracing is usually combined with physiotherapy for optimal outcomes.


Doctors only recommend surgery when rib flaring treatment with physiotherapy and other non-surgical methods has not corrected structural rib flare or when severe cases with significant cosmetic or functional problems persist.
Only a healthcare professional with experience in chest wall deformity should perform specialised rib-flare surgery.

Rib flare surgery is not a single procedure — surgeons choose the most appropriate technique based on the underlying cause, severity, and whether rib flare occurs alongside other chest wall deformities such as pectus excavatum.
Surgeons reshape or trim the protruding cartilage to improve symmetry.
The ribs are surgically adjusted and stabilised in a corrected position.
Initially designed for pectus deformities, but can include rib flare correction.
The Nuss procedure alone does not correct rib flare, but many surgeons add:
A less invasive option focused on smoothing mild flaring.

All surgery carries some risk. Possible complications include:
Choosing an experienced rib flare specialist significantly reduces these risks

Rib flaring is common and treatable. Many patients achieve significant improvement through specialist physiotherapy, breathing retraining, and posture correction. For those with rigid or structural rib flare, surgery offers a long-term, predictable solution.
With UK rib flare surgery costs ranging from £5,000 to £30,000 depending on the procedure, the best first step is a consultation with a chest wall deformity specialist or rib flare physiotherapist. With the right treatment plan, patients can achieve not only a more balanced rib cage correction but also improved breathing mechanics, posture, and confidence.
