Idiopathic scoliosis (IS) is a common problem affecting approximately 3% of the population; its progression can lead to significant health problems. The BrAIST study proved brace effectiveness, which increased bracing interest and utilization globally. There is a lack of evidence-based guidelines for brace treatment. There is significant variability in the brace literature with little consistency in indications for brace treatment goals, brace types, use of monitors, timing of radiographs, and evaluation of skeletal maturity. This lack of evidence demonstrates a clear need for a multi-center brace registry. The first aim of this proposal is to develop a comprehensive retrospective brace registry. This project involves expert clinicians, researchers and an orthotist, each with broad clinical and research experience in the field of bracing for scoliosis. The retrospective registry will function as a pilot, providing strategies to optimize variables, streamline data collection and minimize missing data. The next step will be to develop and launch a multicenter, prospective brace registry and Quality Improvement registry.
