Conservative treatment for adolescent idiopathic scoliosis (AIS) using bracing has proven to be effective at reducing curve progression. However, variation in brace design and lack of brace specificity hamper clinical treatment outcomes as well as the predictability and comparison hereof. To overcome this, recent technological developments aim to generate transparent and objective criteria for brace manufacturing by applying computer-aided design software and additive manufacturing to produce braces for scoliosis treatment. Yet, the extent of its applicability and clinical implementation are to be determined. This study will identify and map the available evidence for the methodology and application of three-dimensional technology for the design and production of clinical braces used for treatment in patients with AIS.

This scoping review will be conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. This scoping review will consider studies on methodology of three-dimensional technological methodology and applications that have been or are currently being applied in brace treatment of AIS. The following databases will be searched: MEDLINE, Web of Science, Cochrane Database of Systematic Reviews and Embase (OVID). Search limits will be applied; for example, only articles written in the English language published after 2000 will be included. The retrieved articles will be screened independently by two researchers. A third researcher will be consulted in case of disagreement. Data from relevant articles will be independently extracted by two researchers and presented in a tabular manner accompanied by a descriptive narration.

Considering the nature of the study, no ethical approval needed to be requested. The study result will be submitted to a peer-reviewed journal.
