Total spine reconstruct surgery

Hey yall , my name is Lore, and im 54, and I have neuro surgeons and orthos at Emory in Atl. The neuro surgeon wants to do a very complex total spinal reconstruct on all 3 levels. These are the biggest of my diagnosis... Degenerative Scolosis, Levoscolosis, Dextro scolosis, Rotary Kyphosis, Ankyling Spondylitis, Spinal Stenosis, Facet disease, numerous broad herniated disc's i.pendong spinal cord and or thecal sac, bulging disc's bone spurs all along spine and most if these are bilateral. Listhesis and I could go on and on. The degree of my curve is 33 to 36 degrees. I've lost 5 inches in height through the years one inch in the last year alone. Are they anything out there for me other tgan that major surgery that is available
