Scoliosis is a disorder that causes an abnormal curve of the spine, or backbone. There is a normal spinal curve when looking from the side, but the spine should appear straight when looking from the front.
Kyphosis is a curve in the spine 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 spine or lumbar spine. People with
scoliosis develop additional curves to either side of the body, and the bones of the spine twist on each other, forming a C or an S-shaped or
scoliosis curve in the spine.
Scoliosis ranges from 10-20 degrees (mild), 20-50 degrees (moderate), and severe (greater than 50 degrees).Scoliosis is about two times more common in girls than boys. It can be seen at any age, but it is most common in those over about 10 years of age.
Scoliosis is hereditary in that people with
scoliosis are more likely to have children with scoliosis; however, there is no correlation between the severities of the curves from one generation to the next.
