Scoliosis
Pronunciation: skoh-lee-OH-sis
A lateral curvature of the spine of 10 degrees or more (measured by the Cobb method), for which orthotic intervention such as a TLSO may be prescribed in skeletally immature patients.
Full Definition
Scoliosis is a three-dimensional spinal deformity defined by a lateral Cobb angle of ≥10° on a posteroanterior radiograph, typically accompanied by vertebral rotation. In orthotic services, bracing is indicated for curves of approximately 25–40° in growing patients to arrest progression, with the Boston and Rigo Chêneau TLSOs being common devices. Editors working on orthotic or orthopaedic documents should note that 'scoliosis' is always spelled with an 's' (not 'skoliosis') and that the degree symbol (°) or the word 'degrees' must be used consistently when reporting Cobb angles. The term 'idiopathic' should be preserved accurately, as it specifies that no underlying cause has been identified.
Usage
Usage note: Always spelled 'scoliosis', not 'skoliosis'. Do not confuse with kyphosis (sagittal-plane curvature) or kyphoscoliosis (combined deformity). Cobb angle measurements must be followed by '°' or 'degrees'; do not omit the unit.
