What is Pars Defect. Pars defect is a painful condition that affects the lower spine. It is actually a stress fracture that occurs in the region of the vertebrae called pars interarticularis (or just pars).The pars interarticularis acts as a bony bridge between joints, and helps to keep the vertebra in place.ars defect is believed to be caused by repetitive strain to the lower back or lumbar section of the spine, and typically affects the fifth and fourth lumbar vertebrae.
Spondylolysis is a breakdown or fracture of the narrow bridge between the upper and lower facets, called the pars interarticularis. It can occur on one side (unilateral) or both sides (bilateral) and at any level of the spine, but most often at the fourth or fifth lumbar vertebra (Fig. 2).ost believe it is due to a genetic weakness of the pars interarticularis. Both spondylolysis and spondylolisthesis can be present at birth or occur through injury. Repeated stress fractures caused by hyperextension of the back (as in gymnastics and football) and traumatic fractures are also causes.
