All have curves in their spine. These curves round our shoulders and make our lower back curve slightly inward. But some people have spines that also curve from side to side. A scoliosis is a lateral or sideways curve in the spine that is apparent when viewing the spine from behind. On an X-ray, the spine of an individual with scoliosis looks more like an “S” or a “C” than a straight line. Scoliosis may have its onset in infancy but is most frequently seen in adolescence. Also, it is more common in females as compared to men.
