Everyone’s spine has natural curves. 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. Unlike poor posture, these curves can’t be corrected simply by learning to stand up straight.
This condition of side-to-side spinal curves is called scoliosis. On an x-ray, the spine of a person with scoliosis looks more like an “S” or a “C” than a straight line. Some of the bones in a scoliotic spine also may have rotated slightly, making the person’s waist or shoulders appear uneven.
Scoliosis is a descriptive term and not a diagnosis. In more than 80% of the cases, a specific cause is not found and such cases are termed idiopathic meaning “of undetermined cause.” This is particularly true among the type of scoliosis seen in adolescent girls. Conditions known to cause spinal deformity are congenital spinal column abnormalities, neurological disorders, genetic conditions and a multitude of other causes. Scoliosis does not come from carrying heavy things, athletic involvement, sleeping/standing postures, or minor lower limb length inequality.
