Re: Artifical disc BELOW Scoliosis fusion
I suspect that the "artificial disc" that Mrs Krier had put in was likely to have been a PEEK spacer, which is like a plastic disc put in to help restore height to the disc space where your own disc had degenerated away. I had one of these put in at L3-L4 during my last surgery, which was a one-level XLIF (anterior fusion) with pedicle screws placed posterially to keep things strong and stable.
Moveable artificial discs have been around for several years now but they are mainly used in cervical and upper thoracic spines. I haven't heard of anyone having a lumbar artificial disc placement yet but there may well be someone out there who has. The main issue has always been that the lumbar spine is under so much more pressure than the upper spine.
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.
