Spondylolisthesis is a condition in which one vertebra slips onto or rubs against another vertebrae in the spinal column. Symptoms of this condition are back pain, pain in the buttocks or leg pain.  Nerves that are pinched by the shifting vertebrae cause discomfort. Most sufferers of spondylolisthesis suffer from a persistent low back pain that is relieved by rest.
Spondylolisthesis can be congenital (present at birth) or develop during childhood or later in life. The disorder may be the result of stressing the spine through gymnastics, football, weight lifting and other athletic activities.
Degenerative spondylolisthesis occurs after age 50.  The natural aging process may also create a narrowing of the spinal canal.
Usually an x-ray, taken from a side-view, can quickly confirm or deny the presence of this condition.
Treatment usually includes two or three days of bed rest, restriction of activities causing stress to the lumbar spine, Physiotherapy, anti-inflammatory and pain reducing medications, and sometimes the outfitting of a corset or brace.
Surgical intervention is considered when the disorder is threatening the function of the spinal cord or if the condition is causing unbearable long-term back pain.
