Abstract
Introduction Whether baseline characteristics influence range of motion outcomes following proximal phalanx fracture remains unclear. The aim of this review was to investigate whether fixation type, time to commencement of active finger exercise, location of fracture or which finger is injured predict total active range of motion 6 weeks after surgical fixation. Methods A retrospective cohort of 49 patients with finger proximal phalanx fracture was analysed. Putative predictors investigated were fixation type, time to commencement of active exercise, location of fracture and injured finger. The outcome of interest was total active finger range of motion 6 weeks post-operatively. Results Multiple regression analysis found that time to commencement of active exercise was the only significant independent predictor of total active range of motion 6 weeks post-operatively. The main influence on time to commencement of active exercise was fixation type, with fractures repaired using Kirschner wire fixation associated with a delay of nearly 2 weeks, compared with fractures repaired using open reduction and internal fixation. Discussion Patients who commence active exercise early following surgical fixation of a proximal phalanx fracture may expect greater total active range of motion 6 weeks post-operatively than if exercise is delayed.
