Re: Great news...more questions for veterans ?!
Hi Mrs K,
If your curve is progressing as it is then most surgeons would advise surgery at this point I think.
I'm very confused by your surgeon saying that your correction will decrease by 10% yearly - does he mean get better or get worse? In either case it's an odd thing to say; you can't straighten out further once you are fused, but neither should you expect to lose that much correction! A little "settling" occurs following the surgery, but once you're fused your spine should stay where it is. I would get this clarified as soon as you can.
Removal of the disc and replacing it with a spacer (to restore the height lost from the missing disc) and then fusing that level is pretty standard treatment for a badly degenerated lumbar disc, whether you have scoliosis or not. It's odd that your first consultant didn't suggest this. Your current surgeon sounds much more on-the-ball. Please don't worry about the discogram; in my experience they are uncomfortable rather than painful.
Hope this helps
37 years old, diagnosed with infantile idiopathic scoliosis at 6 months old with curves of 62(T) and 40(L) degrees. Casting and Milwaukee braces until surgery at 10 - ant release/pos fusion T1-T12, halo traction. Post op cast and then TLSO. Further surgery at 18 (ant release/pos fusion extended to L3 to include lumbar curve, costoplasty) and 25 (another costoplasty). Fusion extended to L4 at 33 (XLIF with 4 pedicle screws and two short rods). Pre-op curves: 76(T) and 70(L). Post-op curves: 45(T) and 35(L). Diagnosed with Ehlers-Danlos Syndrome aged 34; scoliosis almost certainly due to this rather than being idiopathic.
