<s>[INST] I had a laminectomy/Discectomy 1 yearago now I have sharp back pain with leg weakness. Xray showed anterior osteophytes at multiple levels and narrowing at L4/L5 of lumbar. Mri and ct done as well. Dont have those results yet. My surgeon wants to discuss a possible fusion surgery. Good idea or not? [/INST] You are having neurideficit in form of leg weakness. Go for mri  LS spine and look for canal diameter. Decision regarding neurosurgical intervention will depend on these parameters. Hope my answer will help you.  Take care. Don't forget to rate me. </s>
