I don't know if I read all through this thread when trawling everything in the early dark ages. I wish I had!
I read the ISICO stuff a while ago and have been wrestling with those three systems ever since, Hdugger. What has become apparent is that exercise can change the ligament part and enable so-called structural curves to correct. Constant ASCs and side-shifting has radically increased the flexibility/mobility of Tamzin's thoracic "structural" curve. As you say, bone is equally flexible or inflexible in everyone, i.e., doesn't really change significantly. Our exercises haven't done zip to the bone, but they've loosened whatever soft tissue structures (ligament, tendon, muscles, etc.) were stopping the curve being able to SIGNIFICANTLY correct. Surgeons do this all the time before ops: they have patients perform "flexibility inducing EXERCISES" to allow maximum correction during the op. Are surgeons really just closet exercise junkies!
This increased exercise induced curve mobility can destabilise the spine: surgeons slap in some rods; alternatively, why not just bulk up the paraspinals with healthy exercise to hold the spine in the new alignment? Highly corrective bracing must also mobilise the curve, stretch those soft tissue structures. The problem there is that this passive force, when removed, leaves the spine unsupported--one can't just simply THEN start working the muscles and mind to support the spine--it takes constant work, i.e., normal muscular movement during everyday life. There's a spate of interest now in performing exercises while wearing braces--this seems wise to me.
Am I missing something? Is fusion surgery actually changing the fixed, bony structure? Or is it just keeping the spine from bending against the force of the ligaments and muscles?
I think you're spot on, Hdugger.
