    Abstract:
    OBJECTIVE: To evaluate clinical outcomes of bracing and analyze related factors that influence curative effects in adolescents with idiopathic scoliosis, and to investigate indications of bracing. METHODS: Seventy-nine patients with AIS who had no history of prior therapy were treated with a brace. Several parameters were consecutive measured and documented during the period of follow-up including Cobb's angles, curve patterns, menarche status, sitting heights, standing heights, Risser sign, apical vertebral rotation, and so on. RESULTS: The average period of followed-up was 30 months (12 months to 60 months). Twenty-one patients (26.6%) presented curve deterioration, 40 patients have no obvious curve change, 18 patients (22.8%) got a curve improvement. There was significantly lower percentage of curve progression and higher percentage of curve improvement in cases with Cobb's angle less than 35 degrees at the first visit (P < 0.05). The percentage of curve progression was significantly greater in the cases with apical vertebral rotation beyond grade III while the percentage of curve improvement was lower (P < 0.05). Curve patterns, Risser sign and other parameters were found to make their effects on the percentage of curve progression and improvement, which, however, was not statistically significant (P > 0.05). CONCLUSION: Bracing can limit or improve mild and moderate curve of idiopathic scoliosis effectively, especially in cases with initial curve magnitude ranging from 20 degrees to 35 degrees . Risser sign is not a reliable parameter for measuring the outcome of bracing treatment for idiopathic scoliosis. Surgery is advised as soon as possible for the cases with initial Cobb's angles greater than 45 degrees and initial apical vertebral rotation beyond grade III early while bracing did not work.
