Scoliosis Surgery - ST2R (Simultaneous Translation on Two Rods)
Condition: Scoliosis
MeSH terms: Scoliosis
Study type: Interventional

Summary: 
      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.
    

Detailed description: 
      The correction of the deformity in three planes of space is the main goal of surgical
      treatment of children's scoliosis and adolescents.

      The techniques provide a satisfactory correction of the deformity in the coronal plane but
      remain insufficient in the sagittal plane and in particular for the correction of thoracic
      hypokyphosis.

      Dr. Clarke and his team have shown that ST2R reduction technique (Simultaneous Translation on
      Two Rods) associated with the PASS ® system gave a good correction of the thoracic
      hypokyphosis of idiopathic scoliosis. The results of his single-center studies have shown
      that ST2R technique allowed to restore normal thoracic kyphosis with an average gain of 23 °
      in patients preoperatively hypokyphosis, higher than the gains made by other techniques
      (rotation of the shaft, close off Gradually, in situ bending), while providing a frontal
      correction 70%, similar to results reported by other techniques. The results of this
      technique for non idiopathic scoliosis are still to be analyzed.

      The creation of an observatory of children's and adolescents scoliosis (idiopathic,
      neuromuscular, etc ...) operated by the technique of reduction by simultaneous translation on
      two rods with the same instrumentation will:

        -  Firstly, to confirm or refute the first published results idiopathic scoliosis

        -  And secondly to analyze the results of the same technique on all other scoliosis.

      The impact of the intervention on the quality of life of patients is an essential element
      that will be evaluated.
