42 patients were randomized to undergo open reduction and internal fixation for a proximal phalangeal fracture either with or without the placement of a denaturated oxidized cellulose adhesion barrier. The purpose of this study was to determine if an adhesion barrier resulted in significantly different total angular movement, DASH scores, requirement of secondary surgery, and adverse events) when compared to treatment without the use of an adhesion barrier after 6 months. Results demonstrated that all outcomes of interest were statistically similar between study groups throughout the duration of the study, suggesting comparability between intervention and control groups.
