Scoliosis is a
medical condition in which a person’s spinal axis has a three-dimensional
deviation. The main diagnostic criterion is spinal curvature exceeding 10° on a
plain antero-posterior X-ray image.
Scoliosis can
occur before skeletal maturity and persist over time (idiopathic scoliosis) or
it can occur in adulthood (de novo scoliosis). “De novo scoliosis” is due to
disc degeneration,
osteoporosis, and osteoarthritis of the facet joints.“Idiopathic scoliosis”
represents temporal continuity of a spinal deformity, and is already present in
prepuberty or adolescence.
It normally
becomes symptomatic with disc degeneration. Although the etiology of these
conditions is different, they can coexist and overlap .
