Spondylolysis is a stress fracture in the vertebral body in the lumbar spine.
Although this condition can be caused by repetitive trauma to the lumbar spine or strenuous sports such as football or gymnastics, anatomy also plays a major role. In those with spondylolysis, many times the inter-facet region of vertebra L4 is more trapezoidal in shape and wider than a normal vertebra. This also changes the inter-facet height, making them shorter and narrower. With this defect in the spine, a normal load applied to the spine will be greater compared to those without it.
AMEDICA products used to treat spondylolysis include:
- FacetGun® Max Facet Fixation System
- Javelin® MIS Locking Facet System
Ask your doctor which AMEDICA product may be best to treat your condition.
