Can’t speak for anyone else, but I had the surgery in 2007 at age 41. It was an L5-S1 laminectomy/discectomy spinal fusion. I have 2 rods and 3 screws, and mine was done anteriorly and posteriorly, as I was on an inversion table. Had spondylosisthesis with bilateral par defects, as my spine was unstable. My disc between between L5-S1 was in very bad shape also. I chose to have the surgery in order to have a better quality of life, and I’m glad I did. Mine was done at Eisenhower Hospital on Fort Gordon by a very good surgeon.
I’m not going to lie- The recovery is rough and long, but you’re a young man. You’ll get through it. It’s certainly doable, as is the physical therapy.
Find a good surgeon that has done the procedure numerous times- (the more the better), and you should be fine. I went from being severely debilitated and in constant severe pain, to having a normal life again- mostly pain free. I have minimal limitations, and I have no regrets. Best of luck to you.
