The lumbar zygapophyseal (facet) joints: A role in the pathogenesis of spinal pain syndromes and degenerative spondylolisthesis

The zygapophyseal joints in the lumbar spine are important structural components contributing to the stability of the lumbar motion segments. Pathology of the zy-gapophyscal joints in the lumbar spine may be a significant cause of low back pain and segmental instability within the lumbar spine. Management of pathology related to the zygapophyseal joints remains a difficult challenge for the physician caring for patients with spinal disorders. Future investigations with tissue engineering, ligamentous reconstructions, and intervertebral disc replacement or regeneration may have usefid applications in the treatment of zygapophyseal joint pathology.
