Abstract

• The ankle is a complex, weight bearing joint and its injury results in a severe functional disturbance of complex anatomical characteristics. It is very important to understand the mechanism of the trauma in order to make defenite diagnosis and proper treatment. The authors analysed 92 cases(92 patients) of the ankle fractures which were operated in Orthopedic Department, Korea University Hospital from Sept. 1980 to Dec. 1991. The results obtained were as follows ; 1. Of the 92 cases, male was 61 cases(66.3%), female was 31 cases(33.7%) and average age of the patients was 39.9 years. 2. The causes of the injury were slipping down, traffic accident, sports injuries and falling down in orders. 3. Open fractures were 12 cases(13.0%) and closed fractures were 80 cases(87%). 4. The most common type of the ankle fracture was supination-external rotation type(32 cases, 34.8%) and next was pronation-external rotation type(26 cases, 28.3%), according to the classification of Lauge-Hansen. 5. The associated fractures with ankle fracture were 26 cases (28.3%). 6. The best result was supination-adduction type and the worst result was pronation dorsiflexion type, when assessed according to the criteria of Meyer. 7. There were 11 cases of complications(12.0%), in which 6 cases of traumatic arthritis, 4 cases of malunlon and 1 case of nonunion. 8. The accurate reduction and rigid internal fixation to the fracture of lateral malleolus of dlstal fibula and tibiofibular diastasis was important in the treatment of the ankle fractures.
