Prognostic factors for intermediate-term clinical outcomes following Bosworth fractures of the ankle joint

Background: This retrospective comparative study was performed to evaluate the clinical outcomes after surgical treatment for Bosworth fracture-dislocation, and to analyse the prognostic factors related to postoperative outcomes. Methods: Fifteen patients were followed for >= 2 years after Bosworth fracture-dislocation. Twenty-five ankle fracture-dislocations as control group were enrolled to compare clinical outcomes. Clinical evaluation consisted of the AOFAS and Olerud-Molander scores. Patient and injury factors were analysed to identify the outcome predictors. Results: There were no significant differences in either clinical evaluation score as compared to control group (P = 0.245, .302, respectively). The time interval to operation and number of manual reduction attempts were found to be predictive factors for poor outcomes (P = 0.004, .038, respectively). Conclusion: As compared to more common patterns of ankle fracture-dislocations, intermediate-term clinical outcomes after Bosworth fracture-dislocations were statistically comparable. Delayed surgical reduction and repeated attempts at closed reduction appear to be negative outcome predictors. (C) 2018 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.
