Medical Definition of Scoliosis, nonstructural

Scoliosis, nonstructural: A structurally normal spine that appears to have a lateral curve (scoliosis).

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.

Correcting the underlying problem treats this type of scoliosis. The spine itself needs no treatment.

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).
