Scoliosis Surgery - ST2R (Simultaneous Translation on Two Rods)

Although practiced for many years, surgical correction of scoliosis is relatively subject published for idiopathic scoliosis and a few published for other types of scoliosis. This study involves a creation of an observatory of patients undergoing scoliosis by ST2R reduction technique (Simultaneous Translation on Two Rods) associated with the PASS ® system. The main objective is to analyze the three-dimensional correction of the deformity after intervention and its maintenance over time depending on the etiology of scoliosis. This research is conducted in pediatric surgery services specialized in this technique. Correcting radiographic parameters is directly related to the surgical procedure. The quality of life of patients is indirectly affected by the surgery. Secondary objectives are to analyze the surgical technique and to evaluate its impact on the quality of life of patients. This study will firstly to have a better understanding in: * Scoliosis of the children and adolescents and their surgical treatment; * The impact of the surgical procedure by the ST2R technique on the three-dimensional correction, and the patient's quality of life; and secondly, better management of patients requiring surgery for scoliosis as well as a public health impact.
