Does the use of bracing prevent the need for surgery in adolescents with idiopathic scoliosis who are at risk of curve progression?
When compared with observation, bracing significantly slows progression of high-risk curves to the surgery threshold (Cobb angle greater than 50 degrees), with a number needed to treat (NNT) of 4 in the randomized portion of the trial. This benefit is greater with more daily hours of brace wear. (Level of Evidence = 1b)
The Bracing in Adolescent Idiopathic Scoliosis Trial (BRAIST) enrolled 242 affected adolescents; 116 were randomized to wear a brace or to observation, whereas 126 teens preferentially chose between the two options (the preference cohort was added because of low enrollment in the randomized trial). All patients were between 10 and 15 years of age, were previously untreated, and had a Cobb angle between 20 and 40 degrees and Risser skeletal
