What does it mean to me and what should I do if I have "chronic bilateral pars defects at L5"?

Me too!

Spondylolisthesis
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

i have bilateral pars defect in C5, what does this mean?

C5 pars defect

Neck_pain
Are you sure it is C5? L5 (lower back) is much more common... Just checking. If it is indeed C5, there is neck pain and possible instability that may need to be addressed surgically. Please check with a good local ortho spine surgeon to get a good understanding of what you have and make an eductated decision after that. Best of luck!

Can a l5 bilateral pars fracture heal 8 months after injury?

Yes

Injuries
If it was caused by an acute injury, the answer is yes. If your pars defect is developmental (from birth). It will not heal. Get a follow up evaluation. X-rays, an MRI, or bone scan can help determine if there is healing.
