Serrano R, Mir HR, Sagi HC, et al. - Researchers designed a multicenter, retrospective analysis to explore the rate of, and reasons for, conversion of closed treatment of humeral shaft fractures using a fracture brace, to surgical intervention. This study included a sum of 1,182 patients with a closed humeral shaft fracture initially managed nonoperatively with a functional brace from 2005 to 2015 from 9 institutions in nine Level 1 trauma centers across the United States.. In this study, a total of 344 fractures (29%) ultimately had undergone surgical intervention. A 29% surgical conversion rate was distinguished in this large multicenter study, with nonunion as the most common reason for surgical intervention after the failure of functional brace. These outcomes are remarkably different than previously recorded. In the future, these results may be useful when counseling patients on the choice between functional bracing and surgical intervention in managing humeral shaft fractures.
