Yes, I had that fusion back in 2017. I had back and buttock pain from a ski fall. I had the pain somewhat managed with meds but still had bad days. So, I was referred to orthopedic surgeon. He ordered an MRI which supposedly showed(two previously ones did not show anything) spondylolisthesis. Being new to the game, i was anxious to fix something that might be causing the pain. The fusion went without a hitch although recovery wasn't very pleasant. It did nothing to help my pain. If I could go back, I don't think I would do it again. Hope this helps.
