I will be going to Matt Currey's plane truth school this year in Scottsdale and I'll see if there is a fix to malignment in the spine challenged. I took an online lesson and was informed that poor alignment may be a compensation to poor ballflight and when ball direction improves, alignment will follow. I think that may not be the sole story.
Jim Hardy devoted an entire DVD to setup and emphasized its importance.One tip he relayed was placing your hands on your knees prior to gripping the club to get hip and shoulder alignment stacked properly. This does not work if your shoulder girdle and hips are rotated out of plane as they are in scoliosis.
There is also little on the Web regarding scoliosis in golf save for a report of a female pro who grappled with the condition. I think that this is an unrecognized difficulty in learning the game for a lot of golfers but there is virtually no data from the golf professional community.
