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.
With the condition of spondylolisthesis, the pars interarticularis defect can be on one side of the spine only (unilateral) or both sides (bilateral). The most common level it is found is at L5-S1, although spondylolisthesis can occur at L4-5 and rarely at a higher level.mportantly, spondylolysis only refers to the separation of the pars interarticularis (a small bony arch in the back of the spine between the facet joints), whereas spondylolisthesis refers to anterior slippage of one vertebra over another (in the front of the spine).
