Scoliosis is diagnosed as one of three types:
- Idiopathic, which means of unknown origin. More than 80 percent of scoliosis cases are idiopathic.
- Congenital, in which the bones are asymmetrical at birth.
- Neuromuscular, in which the scoliosis is symptomatic of a systemic condition, such as cerebral palsy, muscular dystrophy or paralysis.
