@laughlin1947 once recent MRI, CT studies are done then either one or both a neurosurgeon or orthopedic surgeon can do the job. I’d be sure to get a second opinion too. At 74 I too have scoliosis 22 degree lumbar right and 20 degree thoracic left plus OP, OA and multiple disk bulges of both spinal areas. I had fusion L4-S1 in 1990 after a fall. The recovery will be challenging especially if you’re debilitated before hand. You’ll need to see what the doctors suggest and I agree with others in the MILD procedure can fix you by all means do it. My fusion is with stainless steel plates and screws which have their own issues. These days titanium is used instead with great results. Good luck.
