First end-result of a prospective cohort with AIS treated with a CAD Chêneau style brace.

[Purpose] Specific exercises and brace treatment are the two evidence-based modes of treatment for patients with scoliosis. The purpose of this paper is to present the first end-results from a prospective cohort that commenced treatment in 2011 with a CAD based Chêneau derivate and is then compared to the published results achieved with the Boston Brace. [Participants and Methods] Inclusion criteria for the study, refers to the SRS inclusion criteria on bracing, except the range of Cobb angles which was extended to curvatures of up to 45°. Twenty-eight patients were weaned from their CAD Chêneau style brace. The results of this cohort have been compared with the BRAIST study by Weinstein et al. with the help of the Z-test. [Results] A success rate of 92.9% has been achieved. This was compared to the success rate of 72% in the BRAIST study. The differences were highly significant in the Z-test. [Conclusion] The results achieved with the GBW are significantly and better than the results achieved with the Boston brace. Therefore, the standards for bracing should be reviewed with the results that symmetric compression with Boston bracing is not as successful, when compared to asymmetric high correction bracing results, which allow a standardized classification-based corrective approach.
