Abstract
OBJECTIVE: We aimed to evaluate the Chêneau 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 Chêneau 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 degrees 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 whose initial angle was less than 30 degrees , an initial reduction of higher than 50% with the brace presented the best improvement at the end of the follow-up. We note a significant reduction of the rib hump but not accompanied by a reduction of rotation. Finally, we note a deleterious effect in the sagittal curves, with a slight flatness of the spinal profile. CONCLUSION: The continuous wearing of the Chêneau brace can stabilize the evolution of adolescent idiopathic scoliosis, apart from the forms with major double curves, which are not as accessible to the treatment. However, the improvement comes at the price of a slight flatness of the curves of the spine in the sagittal plane. The loss of the correction after discontinuing the brace is minor. We emphasize, therefore, the necessity to monitor the sagittal aspect of the spine as well as the possibility of early treatment, strict surveillance and prolonged follow-up.
