Évaluation du résultat du corset de Chêneau dans la scoliose idiopathique de l'adolescent Evaluation of the Chêneau brace in adolescent idiopathic scoliosis

Objective. – We aimed to evaluate the Cheneau brace in the orthopedic treatment of adolescent idiopathic scoliosis to better determine the indications under which it could be prescribed. Materials and methods. – This was a retrospective study including 63 patients treated by Cheneau brace for adolescent idiopathic scoliosis between 1997 and 2006. The Cobb angles of the curves in the frontal and sagittal planes as well as rotations and rib hump were measured at the beginning of treatment, with the brace, at the end of treatment and 2 years after discontinuing the brace. A variation of ± 10° in angle was selected to judge the results. Results. – At the end of the treatment, 25.4% of the curves were improved and 60.3% stabilized, with 14.3% aggravated; 5 patients (7.9%) required surgery. At 2 years, the reduction in angle was 1.8 degrees, on average. The best results were obtained for the lumbar and dorsolumbar curves. A significant improvement was noted for the dorsal curves; the major double curves are not as accessible to the treatment. For curves
