I had lamenectomy in 1979 and have had no trouble.
I had bone fusion done in June/1999 and it was schedualed to be done together with the lamenctomy but due to a complication wth the fracture on L-4 the bone fusion got extended longer than anticipated and dr decided not to do the lamenectomy and see ifthe bone fusion worked by it self, not being the condition I had to end up doing the lamenectomy 6 months later. If you trust your Dr. to be a good Dr I would recommend you to have it done at the same time. but most off all I will advise youto trust in the Lord God to have control over the hands of the surgeon and everything will be a success. my surgery was from L-4 -- S-1.
Had laminectomy l3 to s1 recently (April 21rst, 2019) 84 year old, had back pain and leg weakness. Pain is virtually gone at present, Leg weakness still there. At 84 not going to build worn out muscles very quickly. My suggestion is do light physical therapy and walk, walk, and walk as much as you can. But don't quit. My problem was stenosis of the spine, and surgery solved the pinched nerves. It takes awhile for some of them to wake up. Hang in there!
