Within the last year I underwent surgery for spondylolthesis grade 2 between my l5 and s1. All in all it was a decompressive laminectomy with spinal fusion of the l4 to L5 and the l5 to s1. The surgery went well and I returned to a desk job at 7 and a half weeks post opt. The NS is a particular surgeon and I followed his instructions to a T. The orthopedic surgeon sent me to PT at 4 months post op because I was having trouble getting up from laying on my stomach. I told my body to go and it felt like a concrete block. Went in for my 6 month X-rays to find both pedicle screws at the S1 level are broken. Report says possible fusion and MRI showed no signs of infection. My thigh muscle never stops twitching and there is bilateral pain in my lumbar. My questions are has anyone had broken hardware left in them? Does anyone absolutely know why your screws broke? I'm taking a poll... Do you think I'm enroute to another surgery?
