What is scoliosis?
Scoliosis is a side-to-side curve of the spine greater than 10 degrees. The spine of a person with scoliosis can look like a “C” or “S” instead of a straight line. Scoliosis affects 2-3% of the U.S. population.
AIS is a type of scoliosis that occurs in late childhood or adolescence of which the cause is unknown. More than 80% of scoliosis cases are diagnosed as idiopathic. In many cases, AIS curves are stable; however, in some cases, the curve continues to progress over time.
