Lumbar spondylosisthesis occurs when degenerative changes become severe enough that one vertebrae begins to abnormally slip forward upon another. Terms such as subluxation or anterolisthesis are also used to describe spondylolisthesis.
Spondylolisthesis is usually caused by the degenerative effects of aging or a stress fracture from childhood. Spondylolisthesis can narrow the spinal canal and cause symptoms of lumbar spinal stenosis, or pinch a nerve and cause symptoms of lumbar radiculopathy.

In adults, lumbar spondylolisthesis is initially treated by medications, physical therapy, and/or injections. Spinal fusion surgery is often necessary if conservative treatments fail.
