Study designRetrospective cohort study.ObjectiveBracing is an accepted standard therapy for idiopathic scoliosis at Cobb angle ranges between 25° and 40°. However, it is unclear, if a specifically tailored regimen of daytime and nighttime braces (= double brace) yields superior results compared to the standard treatment (single brace for day and night).MethodsOne-hundred-fifteen patients with adolescent idiopathic scoliosis (AIS) were assessed before initiation of bracing treatment and at the final follow-up 2 years after deposition of the brace. They were divided into two groups: double-brace group (n = 66, 4 male, 62 female, age 13.1 ± 1.9 (mean ± SD), primary curvature thoracic n = 35, lumbar n = 31) and single-brace group (n = 49, 8 male, 41 female, age 14.1 ± 1.9, primary curvature thoracic n = 18, lumbar n = 31). Each patient underwent clinical and radiological examinations and Cobb angles were measured.ResultsBoth therapy regimens succeeded to either stop progression or improve scoliosis in over 85% of cases. The nighttime brace showed a significantly higher primary correction than the daytime brace. Nevertheless, there was no significant difference in treatment success in the 2-year follow-up (p = 0.58).ConclusionIt seems to be sufficient to treat idiopathic scoliosis with one well-tailored brace for day- and nighttime.
