My adult onset scoliosis was mostly my lumbar - I am fused T11-Sacrum. 4 of my lumbar discs were basically dried up and gone - but I still had a little bit of my L4/L5 disc. I ended up rupturing that and so I had the nerve pain all the way to my foot. After awhile, I couldn't stand for more than 2 minutes without horrible pain and same for walking - I could barely go 1 block without pain.
At the time, I had 2 daughters engaged and I wasn't willing to have my fusion surgeries before their weddings in case I had a "bad outcome." 4 months prior to the 1st wedding, I had a discectomy to relieve the sciatica pain. It did help somewhat. (of course I still had tons of back pain from bone on bone and all sort of other issues but at least I could walk).
In the 11 months before the next wedding, I could tell I was getting worse. I believe the discectomy destabilized my spine and made me worse. At the time, my surgeon said "This is a bandaid surgery. If you choose this option, I guarantee you I will be seeing you again." But, he understood my predicament and was OK with my choice.
So, you can probably have a smaller surgery and relieve some pain, but in my experience it did make my spine "crumble" faster....
