Rib flaring or flared ribs—when the lower ribs protrude outward instead of resting naturally against the torso—is a concern for many people seeking help for chest asymmetry, breathing issues, or poor posture. Whether the problem is mild or severe, rib flare can affect confidence, comfort, and performance during exercise. If you’re searching for terms such as rib flare treatment, rib flare correction, rib flare physiotherapy, rib flare specialist near me, or rib flare surgery UK, this comprehensive guide explains every available option in straightforward, patient-friendly language.
1. What Is Rib Flaring?
Rib flaring occurs when the costal margins (the lower edges of the rib cage) tilt outward or upward more than normal. It can occur:
- On one side (unilateral rib flare)
- On both sides (bilateral rib flare)
- More visibly during specific positions, such as lying down
- Alongside pectus deformities like pectus excavatum or pectus carinatum
Although rib flare is not medically dangerous, it may contribute to:
- Visible chest asymmetry
- Lower-back arching
- Reduced core stability
- Breathing inefficiency with not very effective breathing pattern
- Discomfort during lifting or running or deep breaths
- Self-consciousness about appearance
Understanding the root cause is essential because treatment varies depending on whether the flare is functional (muscular/postural issues) or structural (bone/cartilage-related).
2. What Causes Rib Flaring?
The underlying cause determines whether non-surgical treatment, bracing, or rib flare surgery is appropriate.
A. Postural Dysfunction
One of the most common causes of rib flare. Poor posture—especially excessive lumbar extension (arching of the lower back)—tilts the rib cage forward, pushing the ribs outward.
Common postural contributors include:
- Prolonged sitting
- Sedentary lifestyle
- Weak abdominal muscles and lower back pain
- Tight muscles (such as hip flexors) with anterior pelvic tilt
- Overactive chest or upper-back muscles
B. Breathing Dysfunction (Diaphragm Weakness)
When the diaphragm is underused and chest-breathing dominates, the rib cage lifts excessively during inhalation. This elevates and rotates the lower ribs outward, determining also ineffective breathing.
C. Muscle Imbalances
Rib flare is often associated with weak or poorly coordinated:
- Internal oblique muscles
- Transverse abdominis
- Diaphragm
- intercostal muscles
These muscles normally stabilise the rib cage during breathing and movement.
D. Structural Chest Wall Conditions
In some patients, rib flare is part of a congenital or structural chest wall difference, such as:
- Pectus excavatum
- Pectus carinatum
- Congenital rib asymmetry
- Scoliosis-related rib rotation
- Cartilage overgrowth
These cases may not respond fully to physiotherapy alone.
E. Growth Spurts, Puberty, or Trauma
In teenagers, rib flare often becomes noticeable during rapid growth. Past rib trauma or fractures may also lead to long-term asymmetry.
3. Non-Surgical Rib Flare Treatment (Highly EffectiveTreatment Option for Most Patients)
For the majority of people, especially those with posture-related or muscular rib flare, rib flaring treatment through non-surgical methods is the first and most successful approach.
A. Specialist Rib Flare Physiotherapy
This is the most effective non-surgical treatment available. A rib flare physiotherapist focuses on three main areas:
1. Diaphragmatic Breathing Training
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:
- Belly breathing
- 360-degree rib expansion
- Exhale-focused rib depression
- Breathing during movement
2. Oblique and Core Strengthening
Weak internal obliques allow the rib cage to flare outward. Specific exercises help stabilise the ribs and pelvis.
Common exercises include:
- 90/90 hip lift breathing
- Dead bug variations
- Side planks with reach
- Wall breathing resets
- Anti-extension core drills
3. Posture Correction
Physical therapists correct:
- Excessive lower-back arching
- Pelvic tilt imbalances
- Thoracic spine stiffness
- Shoulder and rib cage alignment
Who Is a Good Candidate for Physiotherapy?
- Mild–moderate rib flare
- Posture-related flare
- Adolescents with flexible cartilage
- Adults under 40
- Athletes, dancers, gym-goers
- Post-pregnancy rib flare
Expected Results Timeline
- Noticeable change: 6–12 weeks
- Significant improvement: 3–6 months
- Long-term correction: beyond 6 months with consistency
Non-surgical therapy is also recommended before surgery to improve outcomes.
4. Rib Flare Brace
Rib flare bracing is less common than bracing for pectus carinatum, but can be beneficial for adolescents with flexible cartilage.
Best Candidates for Bracing
- Ages 11–18
- Mild structural rib flare
- Flare partly related to cartilage shape
- No severe pectus deformity
Bracing is usually combined with physiotherapy for optimal outcomes.
5. When Is Rib Flare Surgery Needed?
Surgery is only recommended when rib flaring treatment with physiotherapy and other non-surgical methods has not corrected structural rib flare or severe cases where significant cosmetic or functional problems persist.
You may be a surgical candidate if:
- Rib flare is rigid and structural
- There is significant lower ribcage asymmetry
- The flare is linked to pectus excavatum
- Physiotherapy has not helped
- You experience chronic discomfort or breathing issues or chest pain
- You want long-term cosmetic correction
Rib flare surgery is specialised and should only be performed by a healthcare professional with experience in chest wall deformity.
6. Types of Rib Flare Surgery
A. Costal Cartilage Remodelling
Surgeons reshape or trim the protruding cartilage to improve symmetry.
Best for:
Moderate–severe flare, cosmetic correction, and cartilage overgrowth.
B. Rib Osteotomy (Rib Repositioning)
The ribs are surgically adjusted and stabilised in a corrected position.
Best for:
Rigid flare in adults, major asymmetry, or bone-based deformities.
C. Modified Ravitch Procedure
Originally designed for pectus deformities, but can include rib flare correction.
Best for:
Combined pectus excavatum + rib flare.
D. Nuss Procedure With Rib Flare Modifications
The Nuss procedure alone does not correct rib flare, but many surgeons add:
- Cartilage trimming
- Stabiliser placement
- Correction sutures
Best for:
Patients undergoing Nuss for pectus excavatum who also have rib flare.
E. Cosmetic Rib Contouring
A less invasive option focused on smoothing mild flaring.
Best For:
Patients primarily concerned about aesthetics.

9. Risks & Complications
All surgery carries some risk. Possible complications include:
- Scarring
- Infection
- Asymmetry or irregular contour
- Cartilage regrowth (rare)
- Rib instability (very rare)
- Bar displacement (if used during pectus repair)
Choosing an experienced rib flare specialist greatly reduces these risks.
10. How to Choose the Best Rib Flare Specialist
When searching for a rib flare specialist near me, prioritise:
- A thoracic or chest wall deformity surgeon
- Experience with rib flare and pectus cases
- Access to advanced imaging (CT)
- Ability to offer both surgical and non-surgical treatment
- Transparent pricing and realistic expectations
- Before-and-after case studies
A multidisciplinary approach—including physiotherapy—produces the best results.
11. Non-Surgical vs. Surgical Treatment: Which Is Best for You?
Choose Physiotherapy If:
- The flare is mild or posture-related
- You have good rib flexibility
- You prefer a non-invasive method
- You’re willing to be consistent with exercises
Choose Surgery If:
- The flare is structural and rigid
- It significantly affects appearance or comfort
- Physiotherapy has been unsuccessful
- You also have a pectus deformity
- You want permanent correction
Both routes can achieve excellent results when chosen appropriately.
12. Summary
Rib flaring treatment 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.
