I recently had a procedure called AxiaLif. This procedure basically has a rod inserted at the base of the tailbone to access S1. Then a titanium post is placed between S1 and L5. Before the procedure I brought up with my surgeon that all my test results (MRI's and Discography) indicated that S1 and L5 were sacarilized and that L4 and L5 there is a broad based disk protrusion, with a focal right posterior disk protrusion resulting in moderately severe right neuroforaminal narrowing. My Discography also determined fully concordant pain with L4 and L5. I am wondering why my surgeon decided to fuse a disk that was already fused and will that cause more problems at L4 L5? I am 2 weeks post op with no releif in my original pain. Does anyone have any advice of suggestions?
