Lumbar spondylolisthesis is a condition where one vertebra slips forward over another vertebra. The most common cause is the normal wear and tear of aging. Through the years, the discs shrink due to loss of water content, which lessens the cushioning between the vertebrae. In the case of adult degenerative spondylolisthesis, the most common location is between the L4 and L5 vertebrae in the lumbar region of the spine.

Treatment Options for Lumbar Spondylolisthesis
If initial treatment through physical therapy and specific exercises is unsuccessful in controlling the pain, surgery may be required. The surgery performed--usually a laminectomy--is to reduce the pressure on the nerve roots in the area where they exit the spinal canal. A portion of the lamina is removed, and that allows the surgeon access to create more space in the spinal canal to reduce the pressure on the nerve roots.

Another cause of lumbar spondylolisthesis is facet joint deterioration. This is often associated with arthritis, where the facet joints enlarge to compensate for stability. The enlargement of the facet joints and the subsequent canal narrowing creates nerve compression symptoms common with degenerative lumbar spondylolisthesis.
