Not quite as simple. I was a borderline case, but a really complete stenosis at L4-5. It was my choice to opt for a removal of protruding disc parts and bony structures that could be removed. It was needed to work on both sides of the spine, so about 2 hours in total. It had to be total anaesthesia. Still, walked out the clinic the same day. Now, let's see how the recovery goes. I may very well need implants one day, but so far I did not want the ligament (ligamentum flavum) touched, since that holds the spine (while bothering the nerve at the same time. My hope is that I bought some time (and space) and that workout and lifestyle change may make further surgery unnecessary. I will not ski for the next few months and then we'll see. So far so good, but it is way too early to foresee the long term results. Will keep you guys posted. IMO, this is a very good solution for someone who has a less complex problem than I have. Removal of the bulging disc part is a piece of cake in this clinic.
