The lumbar vertebrae are the five vertebrae located in the lower back. The normal curvature at this part of the spine is a front curve, called a lordosis. In cases of exaggeration of this curvature, it is called lumbar hyperlordosis. Most of these lumbar hyperlordoses are neither painful nor disabling when moderate. However, when it occurs early in the growth phase, it can be increased significantly during puberty and cause pain or deformity. An x-ray of the spine will quantify the severity of the curvature and monitor its progress. Care by a physical therapist or sometimes wearing a corset is possible and generally solves the problem.
