There are a wide variety of brace applications available today with different outcomes and different characteristics. The purpose of this study is to compare in-brace corrections of the series applied today to recent Chêneau series braces as presented in literature.
All patients were registered and fulfil the Scoliosis Research Society inclusion criteria for studies on bracing from 2012. A total of 21 female patients matched with the Scoliosis Research Society inclusion criteria. These 21 girls were of an average age of 12.2 years (standard deviation = 1.1). Average Risser stage was 0.38 (standard deviation = 0.68), average Cobb angle was 31.33° (standard deviation = 6.58). In-brace correction from this sample has been compared to the in-brace corrections of other Chêneau samples as published in literature using a test for comparison of two different proportions.
Average Cobb angle in the brace was 10.66°; 34% of the initial angle that makes an in-brace correction of 66%. A significant difference is revealed for some samples and the absolute in-brace correction was highest in our sample showing that the application of the actual state of computer-aided design/computer-aided manufacturing braces leads to better in-brace corrections than many cast-made braces, and also better in-brace corrections when comparing to computer-aided design/computer-aided manufacturing braces as published.
Symmetric braces are outdated. Asymmetric braces allow better in-brace correction when compared to symmetric braces. Asymmetric braces according to the actual, Best Practice® computer-aided design/computer-aided manufacturing standard allow for improved in-brace corrections promising the best possible radiological and cosmetic end results. Future studies on in-brace corrections and outcomes on brace treatment should use the Scoliosis Research Society inclusion criteria for bracing to improve comparability.
