Cobb angle decrease with CAEN brace for adolescent idiopathic scoliosis: A case report

Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity defined by a lateral curvature of the spine with a Cobb angle of at least 10 degrees. The appropriate treatment is chosen based on the patient's maturity (Risser sign), location, severity, and progression risk of curvature. Skeletally immature patients with a Cobb angle above 25 degrees or less with evidence of progression are usually treated with a brace in order to prevent curve progression, therefore preventing the need for surgical correction. Nighttime bracing was developed to ensure brace compliance without compromising the overall effectiveness of brace treatment. We present the case of an adolescent boy with idiopathic scoliosis and progressive spinal curvature who was treated with a type of nighttime brace (CAEN). The overall result was satisfactory, with not only no increase in the final curvature after brace discontinuance but also a 15° decrease relative to the initial Cobb angle.
