This condition is an abnormal curvature of the spine. It most often develops in early childhood, just before a child reaches puberty. A lateral (to the sides) curvature that also occurs with a rotational component is most readily noticed when looking at the body from the back. This is frequently manifested as a shoulder or pelvic asymmetry or an overall imbalance of the trunk to the left or right.
This condition is an irritation or compression of one or more nerve roots in the lumbar spine. Because these nerves travel to the hips, buttocks, legs and feet, an injury in the lumbar spine can cause symptoms in these areas. Sciatica may result from a variety of problems with the bones and tissues of the lumbar spinal column.
