I had a laminectomy with fusion of l2,13,14,15 October 2014. Recovery has been good. Minor discomfort, which was more like soreness than pain when I resumed normal activities. Did have infection 3rd month treated with antibiotics. It is now 9 months after surgery not fusing and one screw in hardware at 15 is loose. NS wants to do revision and remove failed hardware,replace, and add support at S1. 74 years old and wondering what the likely hood of fusion occurring after second surgery. Has anyone had this done at my age and the result. Have been using a back brace and bone growth stimulator for a month but no change. I have been basically pain free but the loose screw can cause the attached rod to move creating both back pain and nerve pain. Would really likes to hear from someone who has experienced revision surgery. New surgery scheduled for Aug 26. As my NS wants it sooner than later.
