Adolescent idiopathic scoliosis is an abnormal curvature of the spine that appears in late childhood or adolescence. Instead of growing straight, the spine develops a side-to-side curvature, usually in an elongated “S” or “C” shape; the bones of the spine are also slightly twisted or rotated.
Adolescent idiopathic scoliosis presents between the ages of 11 and 17 years of age.
Girls are six times more likely than boys to be diagnosed with it . Ballerinas, competitive swimmers and gymnasts have a higher risk of developing scoliosis. If you have a family history of scoliosis your chances of developing it are six percent. These chances rise to 34 percent if you have a twin with scoliosis, and 74 percent if you have an identical twin with scoliosis.
