There are many causes of scoliosis, including congenital spine deformities (those present at birth, either inherited or caused by the environment), neuromuscular problems, genetic conditions, and limb length inequality.
Scoliosis is a condition involving an abnormal sideways curvature of the spine. It can be caused by congenital, developmental or degenerative problems, but most cases of scoliosis actually have no known cause called idiopathic scoliosis. Scoliosis usually develops in the thoracic spine or the thoracolumbar area of the spine. The curvature of the back may develop as a single curve (shaped like the letter C) or as two curves (shaped like the letter S).
