We designed this study to evaluate the functional outcome and to suggest the guidelines in thetreatment of bilnalleolar ankle fractures with clinical and radiological analysis after operativetreatment. We analyzed 35 patients with bimalleolar fractures among 90 ankle fractures and followed upfor more than 1 year. All 36 fractures were classified according to Lauge-Hansen system and theMeyer criteria was used for the clinical and radiological assessment. Seventeen cases(47%) were supination-external rotation(47%), 9 cases(21%) were supination-adduction: 6 cases(17%) were pronation-abduction and 4 cases(11%) were pronation-externalrotation type. Satisfactory results was obtained in 32 cases(89%) according to the criteria ofMeyer in the viewpoint of clinical and radiological analysis. Satisfactory results could be obtained with early anatomical reduction and rigid internalfixation for the treatment of bimalleolar ankle fractures. Distal tibiofibular syndesmosisdisruption could be spontaneously reduced without trans-syndesmotic screw fixation by earlyopen reduction and rigid internal fixation for the bimalleolar ankle fractures. Early and moreaccurate anatomical reduction can reduce the post-traumatic arthritis in cases with moderatetalar displacement and open fractures
