Abstract

Study Design: Retrospective consecutive cohort study. Objective: For patients with mild to moderate adolescent idiopathic scoliosis (AIS), bracing is the standard therapy to prevent progression of deformity. Still, not all patients benefit from treatment in the same way. Therefore, predictive parameters are needed to determine if patients are likely to benefit from brace therapy. Methods: Fourty-five AIS patients treated with a Cheneau brace were evaluated retrospectively. Inclusion criteria were based on SRS-criteria. Whole spine X-rays were performed pre-brace, in-brace, and at least 6 months after termination of brace treatment. Gender, age, Risser's sign, vertebral rotation determined by Nash and Moe grading system, in-brace correction and in-brace time per day were parameters evaluated. Treatment success and failure groups were compared to determine possible predictive parameters for successful brace treatment. Results: Cheneau brace treatment was successful preventing curve progression in 69%. We found significant differences between success and failure group concerning age (14 +/- .22 vs 12.4 +/- .4;P < .001) and Risser's sign (1.71 +/- .16 vs .5 +/- .17;P < .001) at beginning of brace treatment. Most significantly, initial in-brace curve correction was correlated with successful outcome after brace treatment (r = .64 (P < .001)). Conclusions: As one of few studies adhering to the criteria defined by the Scoliosis Research Society our study shows reliable predictive parameters for Cheneau brace treatment success in patients with AIS. Data shown in this paper will help to differentiate AIS patients who are likely to benefit from adequate bracing therapy from those who could rather benefit from early surgical treatment.
