I had a spondylolisthesis of L4 over L5 with marked disc narrowing and a sacralised L5 to S1.
I was told that I would have fusion at both levels going through my front and back and possibly side. In the end the surgeon only fused L4 to L5 although the operation was very difficult and took 8 hours.
Can anyone suggest why L5 and S1 were not fused as originally intended. I am not due to see the surgeon for another couple of months. If it was orginally deemed necessary am I not at risk of further problems at this level?
I still have lower back pain and hip pain.
