Neuromechanics of idiopathic scoliosis shoulders compensates the angular momentum of the pelvis (i.e. when the shoulders rotate clockwise, the pelvis rotates counterclockwise; when the pelvis rotates clockwise, the shoulders rotate counterclockwise). As scoliosis perturbs the architecture of the shoulders, spine and pelvis, gait also differs between patients and non-scoliotic people. Independently of the Cobb angle, the affected vertebra and the age, idiopathic scoliotic people have a larger rachis flexion range of motion and a narrower hips extension range of motion than non-scoliotic people. The range of motion for rachis extension, hips flexion, left and right lateral flexions are similar to non-scoliotic people. After arthrodesis,
Management of scoliosis be braced. However, these are guidelines and not every patient will fit into this table. For example, an immature patient with a 17-degree Cobb angle and significant thoracic rotation or flatback could be considered for nighttime bracing. On the opposite end of the growth spectrum, a 29-degree Cobb angle and a Risser sign three or four might not need to be braced because there is reduced potential for progression. Surgery is indicated by the Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) at 45 degrees to 50 degrees and by the Scoliosis Research Society (SRS) at a Cobb angle of
