I had a pinched nerve l4 l5 stenosis and spondyliosis. I had a laminectomy which carved out space between my L4,L5 to enable me to walk as the pressure and pain on my left leg was extreme. They would not do a spinal fusion due to my osteoporosis which in hindsight now was a blessing. Forteo I am on speeds bone growth which has help me heal. I now believe I will not have to have a spinal fusion as the pain from the pitched nerve has been relieved. I did get, second, third and fourth opinion . I suffered for over 3 years before making my final decision.One Dr just wanted to mask the pain with gabapentin and painkillers which did not work and I did not do two others said my only option was the spine fusion. The fourth doctor said to give me quality of life he would do the laminectomy and then after my osteoporosis improved and I had been on Forteo for a year. He would look again at more surgery if needed. The laminectomy was a one day in the hospital and out. Not much pain. You wear a brace for 6 weeks. The pain relief was instant next day! I hope this helps. God bless
