The goal of this study was to determine whether the available studies provide enough evidence that, in a borderline case of adolescent idiopathic scoliosis with a large (35 to 50 degrees) curve in a skeletally immature patient (Risser 0 to 2) with significant growth potential left, a conservative line of management in the form of bracing can be considered, rather than to rush into a potentially unnecessary major spinal surgery. We reviewed the literature spanning the last 20 years for the results of bracing in this specific group of patients. From the 9 studies selected, a group-specific data extraction was carried out. Three hundred and five patients with a 36 to 50 degrees scoliosis curve and Risser stages 0 to 2 were treated by bracing and the treatment was termed successful in 160 patients. Thus, more than half (52.5%) of the patients were successfully managed with a brace and were spared surgery. The current trend for management of these curves is early surgical intervention, the rationale being the ineffectiveness of bracing in preventing the progression of such a large curve and the difficulty in obtaining satisfactory correction by postponing surgery to a later date. On the basis of our results, we propose a conservative line of management for these curves, in contrast with current views, rather than to rush into a major spine surgery, expecting a favorable outcome with a well-supervised bracing program. If the curve progresses, surgery can always be considered later, keeping in mind the excellent correction obtained with the pedicle screw systems even for large curves of 70 to 100 degrees.
