Re: Hope for adults with moderate scoliosis?
Replacing all of the IV discs probably wouldn't help much, because the discs themselves aren't causing the scoliosis. Discs can become wedge-shaped after a scoliosis has developed, but they are a symptom rather than the cause of a spinal curve.
Surgeons are usually reluctant to put an artificial disc into a patient with scoliosis; this is because it is thought that the artificial disc would wear out fairly quickly due to the uneven loads on the spine.
I too am hoping that fusionless surgeries become available for kids with Adolescent Idiopathic Scoliosis. Bear in mind that the growth rods available for young children are as restrictive as fusion; they also prevent bending and twisting movements. They are just designed to be lengthened so the child is able to grow. Since growth rods are typically used in kids who have large curves, the goal is usually to allow them to grow as much as possible and then to do a spinal fusion surgery anyway.
Vertebral Body Stapling is different in that it is designed for kids/adolescents with curves of under 40 degrees. These kids do have a chance of avoiding fusion altogether.
Sadly there is currently no way to reduce scoliosis in adults that doesn't involve either surgery or physiotherapy. It would be awesome if there were! If you like going to the gym, we've had reports of success in reducing scoliosis by using a torso rotation machine. I've also heard of adults wearing the Spinecor brace (a soft brace made from bands of elasticated fabric) who have been pleased with the effect on their appearance.
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.
