PS: an echo as I head deeper into my cave...
For those confused about the meaning of "structural curve", read the Maruyama papers cited by Weiss in the above paper, there go out yonder and feel how ADULT 60 degree + curves can "instantly correct" or how juvenile and adolescent 40 - 55 degree curves "instantly correct". Sustaining the correction is the challenge. Also consider that many posters in here fail to indicate relevant details fleshing out the bare Cobb angles measured from x-rays. E.g., how long out of brace was the person before the x-ray. What activities were they doing the day before, or that day: e.g., dancing, horse riding, gymnastics. How tired were they...did their posture collapse...were they tense during the x-ray...so how much of the 5 - 20 degree range of spinal movement were they using as the x-ray machine snapped an instant? For the 30 degree range of kids, were they ever in danger of progression??? How much growth did they have remaining? Did the bracing or PT worsen their rotation (i.e., make it more likely that the curves will progress after the main growth spurt period).
These questions are important, but to dump Chiari/SM related scoliosis from the AIS or JIS is as sensible as dumping the ballerina, horse rider, donut muncher and skateboarder related scoliosis from the search. My daughter's last spine surgeon, a reputable guy, categorically placed her in the JIS category. His published papers are well regarded. He works with cutting edge scientists such as Stokes, Dangerfield, Burwell et al. And he learns from parents too.
