Spondylolysis – Definition
Spondylolysis is a stress fracture. It occurs in a part of the vertebrae (spinal bone). The pars interarticularis is a portion of the bone between the facets. There is a right and left section.
This condition occurs in the lower back. About 90% of the time it is in the lower back. It can fracture on one or both sides (bilateral). Left untreated, it can lead to spondylolisthesis. This is a more serious condition. The vertebra slips forward on the one below it. Both conditions can cause back pain.
This fracture is the most common cause of back pain in adolescent athletes.
Spinal stenosis – Definition
Spinal stenosis is a narrowing of the spinal canal. The spinal canal is located within the backbone. It is a small space that holds the nerve roots and spinal cord. If this space becomes smaller, it can squeeze the nerves and the spinal cord. This causes pain and other symptoms. Stenosis can occur anywhere along the spinal cord. It is most common in the low back (lumbar) region.
