ObjectiveTo assess the effectiveness of bracing in adult with scoliosis.DesignRetrospective cohort studySettingOutpatients followed in 2 French tertiary care hospitalsParticipants38 adults with non-operated progressive idiopathic or degenerative scoliosis treated by custom-molded lumbar-sacral orthosis (LSO), with a minimum follow-up time of 10 years before bracing and 5 years after bracing. Progression was defined as a variation in Cobb angle ≥ 10° between the first and the last radiograph before bracing. The brace was prescribed to be worn for a minimum of 6 hours per day.Interventionnot applicableMain outcome measureRate of progression of Cobb angle before and after bracing measured on upright 3-foot full spine radiographs.Results38 patients were included. At the moment of bracing, mean age was 61.3 ± 8.2 years and mean Cobb angle was 49.6 ± 17.7 degrees. The mean follow up time was 22.0 ± 11.1 years before bracing and 8.7 ± 3.3 years after bracing. For both types of scoliosis, the rate of progression decreased from 1.28 degrees/year ± 0.79 before to 0.21 ± 0.43 after bracing (p<0.0001). For degenerative and idiopathic scoliosis, it dropped from 1.47 degrees/year ± 0.83 before to 0.24 ± 0.43 after bracing (p <0.0001), and 0.70 degrees/year ± 0.06 before to 0.24 ± 0.43 after (p=0.03), respectively.ConclusionsFor the first time, this study suggests that underarm bracing may be effective in slowing down the rate of progression in adult scoliosis. Further prospective studies are needed to confirm these results.
