Hi, I had a 360 fusion at L5/S1 with hardware, cages, screws, etc. Well they are saying it isn't fused, a screw is loose and I need another fusion. My new Dr informed me he is more worried about my spine being unstable than the pain. He told me the new fusion would have an 80% chance of fusing, a 1 in 2000 chance I could have more pain and also a chance I could become impotent cause he needs to go in through the front. Other Dr never told me any of that. Just want to say that after the first fusion my pain got way worse. He will not have to go in through the back this time. Last time they did both the front and back. He just needs to replace the cage. It was such a painful ordeal last time that I'm scared to get it done again. Does anybody think I should do it? There is only one pro and several cons! Dr said if the hardware breaks that I'll really be in trouble. I just don't know what to believe anymore. I have lost total faith in the medical system and think Dr's are just business men! Two doctors say it isn't fused but 2 previous doctors (the ones that did the surgery) say it is.
