Patterns of Rib Hump
A rib hump (also called a rib prominence or Adams forward bend test positivity) is the visible elevation of one side of the rib cage relative to the other when the individual bends forward at the waist. It is the primary clinical sign of structural scoliosis — a three-dimensional spinal deformity involving lateral curvature and vertebral rotation. As the spine curves and rotates in scoliosis, the attached ribs are displaced, producing the characteristic asymmetry visible on forward bending. The vast majority of scoliosis is idiopathic (without identifiable cause) and most commonly presents in adolescence during growth spurts — adolescent idiopathic scoliosis. Less commonly, scoliosis may be congenital (vertebral malformation), neuromuscular (cerebral palsy, muscular dystrophy, spinal muscular atrophy), or degenerative (adult-onset). The degree of curvature (measured as Cobb angle on spinal X-ray) determines management: mild curves may be monitored; moderate curves may require bracing in growing children; severe curves (typically >40–50 degrees) may require surgical consideration. A rib hump is not itself painful in most cases of idiopathic scoliosis.

The Evidence
Evidence context
What research and clinical practice say about rib hump as a sign of scoliosis, and how different approaches contribute to care.
Overall pictureHigh evidence base
A well-understood clinical sign with clear assessment pathways
Rib hump is a reliable indicator of structural scoliosis, with strong evidence guiding monitoring, bracing, and surgical thresholds. Complementary approaches including scoliosis-specific physiotherapy and adapted movement practices have growing support for symptom management and postural control.
When to seek urgent assessmentCertain presentations of rib hump require prompt professional evaluation — do not delay.
A rapidly progressing rib hump in an adolescent warrants urgent orthopaedic review. Scoliosis accompanied by leg weakness, bladder changes, or other neurological symptoms requires urgent spinal assessment. New rib prominence in an adult without a prior scoliosis history also needs structural evaluation. Respiratory compromise associated with significant curvature requires pulmonary function assessment.
What the evidence supportsEvidence for scoliosis management spans monitoring, bracing, surgery, and scoliosis-specific physiotherapy.
Bracing has strong evidence for slowing curve progression in skeletally immature patients with moderate curves. Surgical spinal fusion is well-supported for curves approaching or exceeding 50 degrees. Scoliosis-specific physiotherapy methods — including Schroth and SEAS — have evidence for reducing progression and improving postural control in mild to moderate idiopathic scoliosis. Adapted yoga and Pilates show emerging evidence for adult symptom management.
Understanding the clinical pictureRib hump reflects vertebral rotation in scoliosis — its significance depends on curve severity and age.
The Adams forward bend test is the standard clinical screen for scoliosis. Cobb angle measurement on spinal X-ray determines management thresholds. Most scoliosis is idiopathic and presents in adolescence, but congenital, neuromuscular, and degenerative forms exist. Curve severity, skeletal maturity, and underlying cause all shape the appropriate care pathway.
Complementary approaches in scoliosis careScoliosis-specific physiotherapy and adapted movement practices play a recognised role alongside conventional care.
Schroth Method physiotherapy and SEAS are structured, evidence-informed approaches that focus on three-dimensional postural correction, breathing, and muscular activation. They are most effective when integrated with medical monitoring rather than used in isolation. Pilates and yoga adapted for scoliosis may support body awareness and comfort in adults, though neither replaces structural assessment or medical oversight.
Holistic contributions to living with scoliosisPostural awareness, breathing optimisation, and movement quality are meaningful targets for holistic practice.
Osteopathy and chiropractic may address associated musculoskeletal discomfort and movement restrictions, though structural curvature is not resolvable through manual therapy alone. Somatic movement practices can support body awareness and quality of life. Holistic approaches are most valuable as part of a coordinated care plan that includes appropriate medical review.
Safety considerationsSome activities and interventions carry specific risks in the context of scoliosis.
High-impact axial loading activities should not be undertaken without prior assessment in significant scoliosis. Spinal manipulation without prior imaging is not appropriate where scoliosis is unknown or where neurological symptoms are present. Any practitioner working with a person who has scoliosis should be informed of the condition, its severity, and any existing medical management plan.
