Additionally, what exactly are the measures of success? Cancer really has only two: are you still alive, and have you had another occurrence of cancer.
What would be the equivalent, clear measures for a scoliosis patient? Neither the surgery or the disorder is likely to kill them, and it would just be a judgement call when you measured an "occurrence" after the original surgery. Is an occurrence the onset of pain? Is it some additional curving? How much? Is it the need for revision surgery.
