Comparative analysis of Boston and Cheneau braces in treating scoliosis: A 2-year follow-up study on curve reduction

Abstract

Background: Scoliosis, characterized by the lateral curvature of the spine, impacts the spine's alignment in three dimensions. Braces are commonly employed as a conservative treatment for individuals with scoliosis, particularly those with curves ranging from 20 degrees to 40 degrees. This treatment approach's primary objectives include arresting the deformity's progression, enhancing clinical appearance, alleviating pain, improving overall quality of life, and circumventing the need for surgical intervention. The aim of this study was to compare the effectiveness of Boston and Cheneau braces in individuals with scoliosis. Methods: In this retrospective study, 51 subjects were included and monitored over 2 years. The primary parameters under evaluation encompassed the severity of both primary and secondary curves and compliance with the prescribed treatment. The subjects were classified into 2 groups: those utilizing the Cheneau brace and those employing the Boston brace. Results: The initial mean values of the primary and secondary curves during the first visit were 37.6 ( +/- 7.4) and 30.1 ( +/- 9.7) degrees, respectively. However, the in-brace curve measurements for the primary and secondary curves were 31.5 ( +/- 1.3) and 22.3 ( +/- 13.3) degrees, respectively (p-value = .0). The mean compliance values of subjects using Boston and Cheneau braces were 16.8 and 17.3 h per day, respectively (p-value = .1). No significant difference was observed in the correction achieved with the Boston and Cheneau braces during the follow-up period. Conclusions: The results of this study demonstrated a significant reduction in the scoliotic curve while under brace conditions. However, the degree of correction achieved did not significantly differ during the follow-up periods. Additionally, there was no notable variance in the correction obtained between the Boston and Cheneau braces.
