What is scoliosis?
Scoliosis is an abnormal curvature of the spine. It is actually natural and healthy for the spine to curve from front to back. This type of curve is only visible when viewed from the side. Kyphosis is a curve seen from the side in which the spine is bent forward. There is a normal kyphosis in the middle (thoracic) spine. Lordosis is a curve seen from the side in which the spine is bent backward. There is a normal lordosis in the upper (cervical) spine and the lower (lumbar) spine.
