Scoliosis is a curve in the front to back plane (coronal plane) of greater than 10 degrees. This curve can be idiopathic (an unknown cause commonly seen in adolescents), degenerative (caused by typical disc disease but with asymmetric wear instead of common symmetric wear), antalgic (caused by pain and not structural) or congenital (abnormal formation of the spine from birth). Scoliosis may or may not need to be treated depending upon the grade of the curve and the symptoms that are generated by the curve. If the curve is less than 10 degrees, it is not considered scoliosis.
