Scoliosis even when untreated, with mortality rates similar to the general population. Older beliefs that untreated idiopathic scoliosis necessarily progresses into severe (cardiopulmonary) disability by old age have been refuted by later studies. The many causes of scoliosis include spinal deformities, neuromuscular problems, and inherited diseases or conditions caused by the environment. An estimated 65% of scoliosis cases are idiopathic, about 15% are congenital, and about 10% are secondary to a neuromuscular disease.
