I had a 2 level PLIF last July after a powerlifting accident. The surgery was a success and I returned to work after five months. I am a heavy equipment operator and got into an accident a few months ago at work and re-injured myself. My NS sent me for a myelogram after injections and PT gave me no relief. The report came back that a piece of bone from the fusion site had broke off and actually displaced the S1 nerve he wants to do surgery next week to fix the problem and told me that this will be a very complex surgery. As Im sure you can imagine I was in shock and didnt really ask what kind of surgery would be needed to fix the issue. I am wondering if anyone might have a ballpark clue as to what he might do and what i can expect the second time around. I know that the 2 level fusion was alot to bear, so I can only imagine what this will be like. Thanks for the advice.
