pre-treatment factors associated with the success of applying the RSC brace were a high Risser score [odds ratio (OR) = 2.97, 95 % confidence interval [CI] 1.18-7.44; p = 0.02), a low Cobb angle (OR = 0.92, 95 % CI 0.85-0.99; p = 0.02), and low ATR (OR = 0.86, 95 % CI 0.75-0.99; p = 0.04).
CONCLUSIONS: The treatment of mild to moderate AIS with the RSC brace provides excellent clinical results. Its added benefit is enabling a three-dimensional correction of a three-dimensional deformity. Pre-treatment high Risser score, low Cobb angles, and low ATRs are associated with treatment success.
LEVEL OF EVIDENCE: Retrospective analysis, Level III.
