Are the flexion and extension views done by xray? To positively diagnose the pars defect, they did a CT scan and xrays where i had to bend forward and then bend backward (or try to). I have also had an MRI which showed nothing. I also have numbness & tingling down one leg - if i touch my outer thigh, i can feel it in my inner calf. The first denial said that I didn't have enough nerve damage to warrant surgery, but they did no nerve conductivity tests. This new denial basically denied the surgery because there was no proof of spondylolisthesis, but from everything I have read there have been cases of fusion done for the spondylolysis by itself...is it possible that even tho I am in constant pain that I have to wait for something more severe to happen for them to approve surgery???
Outside of surgery, can you suggest any other treatment options? I feel like I need to do something more than just sit around and wait for my condition to progress to a point where I either have more nerve damage or it develops into spondylolisthesis.
