Hello NCAirPatrol,
Welcome to the NeuroTalk Support Groups.

You might find more information regarding your condition if you're able to copy your post over to the
Spinal Disorders and Back Pain Forum

There is a Forum search feature too which can be helpful. Users just need to type in their keywords e.g. spondylolisthesis or anterolisthesis etc., and it will bring up past posts or threads.

All the best to you.
