Le traitement de la scoliose idiopathique de l'adolescent par le corset de Chêneau Premiers résultats de l'expérience Lilloise - A propos de 26 cas avec un recul moyen de 16 mois

Abstract

This study aims at presenting the preliminary result of personal experience using the Cheneau-brace in the treatment of idiopathic scoliosis in 26 cases. The average follow-up was 16 months. In every case, wear compliance was perfect ( brace worn 23h out of 24h). At the beginning of the treatment the 19 girls and 7 boys, whose average age was 15 years and 3 months, had a Risser test below 2 in 50% of the cases. At follow-up 69% of the patients had a Risser test higher than 3. In every case but one , the curves were thoracic, lumbar or combined. In frontal plane 73% of the patients were improved and 27% stabilized to within 2 degrees. Initially the average frontal Cobb angle measured 30° at thoracic level and 24° at lumbar level. At follow-up the average improvement was respectively 27% and 37,5%. In sagittal plane a 23% angular loss at dorsal level and a 9% loss at lumbar level were detected at follow-up with brace. We did not notice any effect on vertebral rotation but the movement of translation of the apical vertebra toward the chest wall in the convex side was improved (23%). We confirm that Cheneau-brace is efficient in the conservative treatment of adolescent idiopathic scoliosis but we must point out a decrease of kyphosis and lordosis was detected.
