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

<bold>Background: </bold>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.<bold>Methods: </bold>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.<bold>Results: </bold>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).<bold>Conclusion: </bold>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. [ABSTRACT FROM AUTHOR]
