Scoliosis is a lateral curvature in the normally straight vertical line of the spine. When viewed from the side, the spine shows a mild roundness in the upper back and inward curvature of the lower back. The most common type of scoliosis is idiopathic; it is present at birth and may be inherited. Other types include neuromuscular scoliosis and degenerative scoliosis. Idiopathic scoliosis usually affects those ages 10-16, progressing during the growth years. Some clues that a child may have scoliosis include uneven shoulders, a prominent shoulder blade, uneven waist, or leaning to one side. Diagnosis includes a bone exam and an X-ray to evaluate the magnitude of the curve. Treatment for scoliosis includes back braces, and in more severe cases, surgery that involves joining the vertebrae together permanently (spinal fusion).
