Meta Analysis Comparative StudyA meta-analysis of the efficacy of non-operative treatments for idiopathic scoliosis.
With use of data culled from twenty studies, members of the Prevalence and Natural History Committee of the Scoliosis Research Society conducted a meta-analysis of 1910 patients who had been managed with bracing (1459 patients), lateral electrical surface stimulation (322 patients), or observation (129 patients) because of idiopathic scoliosis. Three variables - the type of treatment, the level of maturity, and the criterion for failure - were analyzed to determine which had the greatest impact on the outcome. We also examined the effect of the type of brace that was used and the duration of bracing on the success of treatment. ⋯ The weighted mean proportion of success for the six types of braces included in this review was 0.92, with the highest proportion (0.99) achieved with the Milwaukee brace. We found that use of the Milwaukee brace or another thoracolumbosacral orthosis for twenty-three hours per day effectively halted progression of the curve. Bracing for eight or sixteen hours per day was found to be significantly less effective than bracing for twenty-three hours per day (p < 0.0001).
