The implementation of an enhanced rehabilitation after surgery (ERAS) program in major orthopedic surgery and in scoliosis surgery in children and adolescents has become a marker of good practice. Investigators are already applying anesthetic, surgical, peri-operative medicine and rehabilitation techniques allowing accelerated and improved rehabilitation for scoliosis operated patients in the establishment. To improve patient care, the Investigators want to develop the ERAS program. The objective of this research will be to validate the feasibility of getting up early on D0 in post-anesthesia care unit (PACU) or ICU in children who have just had surgery for idiopathic scoliosis.
