I had a lumbar fusion of the L-4 L-5 S-1 two years ago. My stenosis/arthritis has progressed significantly past the where the fusion took place and as a result is greatly affecting my daily activities. My doctor wants to remove the hardware, as the fusion was a success at that joint, clean out the arthritis, and fuse the next level with some kind of bone compound without using hardware as he says it would limit my movement greatly. Has anyone had fusion with instrumentation ? If so what were the results? My doc says recovery will be a bit linger without the hardware.
