Nonstructural scoliosis

A structurally normal spine that appears to have a lateral curve (scoliosis).</P> Nonstructural scoliosis involves a temporary change of spinal curvature.

This is caused by an underlying condition such as a difference in leg length, muscle spasms, or inflammatory conditions, (e.g.

appendicitis), which may produce muscle spasm.</P> Correcting the underlying problem treats this type of scoliosis.

The spine itself needs no treatment.</P> Nonstructural scoliosis is also called functional scoliosis.

This is in contrast to structural scoliosis in which there is a fixed curve of the vertebrae (the bones of the spine).
