It turns out my MIL apparently is good friends with Dr. Fessler who is a distinguished spine surgeon and inventor of minimally invasive (endoscopic) scoliosis surgery. My MIL is getting quite a bit of pressure from her doctor friends so we are getting quite a bit of pressure to contact Dr. Fessler as a consult on any possible surgery for our daughter. I have not idea about why one would get traditional open back scoliosis surgery versus the less invasive. DD's curve is thoracic if it makes any difference. Does anyone know anything about this type of surgery and the criteria for it versus traditional spinal surgery?
