Re: ? about rib / hip rubbing
I had it with only a moderate thoracolumbar curvature. It was more due to the fact that I had a surgically induced (first surgery was done by a non-specialist - absolutely *not* to be recommended) kyphosis at the back of my waist, and when I then keeled forward in full blown flatback, sure enough, my ribs started grinding on my hip. I see no reason for it not to happen even with a fairly minor scoliosis, as long as the kyphosis is suitably shaped and positioned, so I wouldn't worry too much as it shouldn't make it unfixable or anything like that
Diagnosed at 15 with 50° curve, but probably juvenile IS. Fused in kyphosis (by non-specialised ortho) with a/p surgery T10-L2 @ 21, posterior only revision surgery to correct kyphosis @ 29. Now 38 with further revision surgery and extension of fusion to sacrum required to correct residual kyphosis, restore lordosis and address spinal stenosis.
