Bilateral L5 Pars Interarticularis Defects
What is the basic meaning when MRI shows Bilateral L5 pars Interarticularis defects without subluxation? This incurred after a multiple car accident.
Spondylolysis: Spondylosysis, or pars interarticularis defect, is essentially a stress fracture of the narrow bridge of bone between vertebral body and the spinous process of the vertebrae. This is not an uncommon condition following repetitive trauma (seen also in gymnasts and football players). Subluxation occurs if the fracture separates from normal position and becomes displaced. ...Read moreSee 2 more doctor answers

Defect of spine: A pars defect of the lumbar spine involves a part of a vertebra called the pars interarticularis. " A defect in the pars is a break in this portion of bone.

This condition is a precursor to another condition called spondylolisthesis, which allows slipping of a vertebra in relation to the vertebrae above or below it. Previously, it was assumed that pars defects were congenital anomalies, or birth defects. Today, we understand that most pars defects are really stress fractures that usually occur in the spines of young people. The presumed cause is repeated hyperextension ...Read moreSee 1 more doctor answer
