Bilateral Par Defect
Lumbar Pars Defect: The defect is a stress fracture of the posterior portion of the spine that connects the facet joints and lamina with the anterior vertebral body at the level of the pedicle. This process is also known as a spondylolysis. It occurs in 5% of the general population but can be as high as 15% in certain athletes like gymnasts and football lineman due to the lumbar hyperextension. ...Read more

Me too!: Bilateral pars defects are genetic defects of the spine that mean that the joints that hold the spine together at that are, and you could be more prone to spondylolisthesis--the top vertebra slipping over the bottom, which can case back pain, and radicular pain from pinched nerves. My mother had this, and so do i. Mine caught earlier because i was a gymnast--didn't know i had this until too late. ...Read more

I have bilateral foraminal stenosis present at l4l5 with bilateral pars defect at L4 and am curious if the pars and stenosis can heal without surgery?

If the pars defect was an acute fracture it has the potential to heal without surgery. But even if it doesn't or if not an acute fracture type, 90% are treated non op while only 15% of stenosis cases end up with surgical intervention. ...Read more
