I had L1 and L2 fusion in march 07 due to severe slipped disk (cause by kyphosis which was mainly corrected by bracing). after the surgery the pain was a whole lot better, almost completely gone even, for about 6 months. it then started to go down hill to the point where i am in constant pain again and living on painkillers. In the last few months it has got a lot worse and i am struggling with day to day life.
My surgeon has decided that he thinks one of the screws (i have 3 screws, a rod and a cage surrounding the fusion) used during fusion may have moved (or is moving) and pressing on or damaging a nerve or even the spinal canal. He said that if this is the case he would like to operate to remove the screw. he also said that while this operation could minimize or completely fix the problem and get rid of the pain for good, it could also go the other way and cause a lot more problems. I think if he offered it to me i would probably have the surgery as I am only 19 and can't do much with my back as it is at the moment, i don't really have much to loose, especially as it is getting worse quickly.
Does anyone have any experience with removing fusion metal work? or know what the risks may be? or have any advice even?
