Twenty-seven trimalleolar fractures in which the posterior malleolar fragment was shown to comprise more than 25% of articular surface or displaced more than 2mm were followed for thirty-five months. Fifteen patients had the internal fixation of the posterior malleolus and twelve did not. All associated medial and lateral malleolar fractures were intemally fixed after open reduction. When satisfactory reduction of the posterior malleolus was achieved after reduction of lateral malleolus, the internal fixation of posterior fragment was not done. The results with and without internal fixation of the posterior malleolus were compared clinically and radiographically: clinically, subjective-ankle score, objective-ROM limitation were assessed and radiographically, arthritic change, posterior subluxation of talus and maintenance of the posterior malleolus without fixation were assessed. Radiographically, further displacement of posterior malleolus were noted in two cases in without fixation group. There were four arthritic changes in fixation group and three in without fixation group. Posterior subluxation of talus was not occurred in two groups. In the clinical results with and without internal fixation of posterior malleolus, there was no statistically significant diffrence in two groups.
