Scoliosis is a curving of the spine. The spine curves away from the middle or sideways.

Spinal curvature; Kyphoscoliosis

There are three general causes of scoliosis:

• Congenital (present at birth) scoliosis is due to a problem with the formation of the spine bones (vertebrae) or fused ribs during development in the womb or early in life.
• Neuromuscular scoliosis is caused by problems such as poor muscle control or muscle weakness, or paralysis due to diseases such as cerebral palsy, muscular dystrophy, spina bifida, and polio.
• Idiopathic scoliosis is scoliosis of unknown cause. Idiopathic scoliosis in adolescents is the most common type.

Some people may be prone to curving of the spine. Most cases occur in girls. Curves generally worsen during growth spurts. Scoliosis in infants and young children are less common, and commonly affect boys and girls equally.
