Spondylolisthesis is a condition where spinal vertebrae slip forward over one another. This is often caused when the crack of a pars fracture (spondylolysis) affects both sides of connection between the lamina and pedicles. In this way, spondylolisthesis can be a direct result of spondylolysis. However, spondylolisthesis can also be caused by the deterioration (degeneration) of the facet joints and discs of the spine, independent of any fracture. This is known as degenerative spondylolisthesis.
Symptoms can include:
- Localized lower back pain
- Pain that radiates down to the legs (if there is associated nerve compression)
