Scoliosis Research Society
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.
