What Causes Scoliosis?
Scoliosis is the presence of an abnormal curvature of the spine. Scoliosis may affect the cervical (neck), thoracic (middle) and lumbar (lower) regions of the spine. The curves, which veer to the left or right, often present in an S- or C-shape. These curvatures may be categorized as non-structural — meaning the curve is temporary and the spine is structurally normal — or structural, meaning that the spine has a fixed curve.
