NeuroCare Brain & Spine Center - Common Spinal Conditions
Spondylolysis is a stress fracture or defect involving the pars intra-articularis of one of the vertebrae of the spine. The pars intra-articularis connects the vertebral body (front part of the vertebrae) to the back of the vertebrae.
A fracture can occur at the pars intra-articularis due to repetitive movements of extension and rotation which lead to an increase in forces in the lumbar spine. Since the pars intra-articularis is small, it is unable to absorb repetitive shock which can lead to fracture.
This condition occurs in the lower back. Left untreated, spondylolysis can lead to spondylolisthesis. This is a more serious condition in which one vertebra slips forward on the one below it. Both conditions can cause back pain by disturbing biomechanics in the back or by pinching a nerve as it leaves the spinal column.
