I would be interested to know how many discectomies have lasting effects, where no further surgical intervention is needed. It seems from the research that I have done that, more often than not, a spinal fusion seems necessary in the end. I have had a neurosurgeon's recommendation for discectomy, followed by an orthopaedic surgeon's recommendation for spinal fusion at L5/S1. I'm really concerned about scar tissue, which will be less with discectomy, but if another surgery is eventually required at that site? I'm equally concerned about the aggressive approach of the spinal fusion, is it worth it to skip the less invasive discectomy and end up only having one surgery?!
