I had a spinal fusion done March 2005 from Spondylolisthesis fusion was from L4 - S1 region for the last year I been getting numbness down legs pain in legs, feet tingling , numbness at surgery site. I can't sit, walk, stand, reach, strech or bend. The say I now have Spondylolisthesis and anteriolisthesis at L5 - S1 region but no surgery option as the grafts look good just one of the screws was losening. The grade is 2/5 is there anything I can do to improve this as I have been off work and might not be able to return to work ever again. My surgeon said everything looked fine with the grafts at the time but said 2 months from now could be another story.
