Abstract:
In the treatment of malleolar fracture, anatomical reduction and rigid internal fixation are essential to prevent the complications such as infection, malunion or nonunion, traumatic arthritis, skin necrosis and joint contracture. But it is often difficult to obtain rigid fixation for medial malleolar fracture because of its comminution or thin cortex with osteoporosis. Generally, two operative methods are available for medial malleolar fracture, which are malleolar lag screw fixation and tension band wiring. The purpose of this paper is to analyze which operative method is better for anatomical reduction and rigid fixation and has less postoperative complications for medial malleolar fractures. From March 1992 through March 1995, 88 patients had undergone surgical intervention for medial malleolar fractures. The patients were divided into 2 groups according to operative method for medial malleolar fracture. For one group, malleolar lag screw together with or without a K-wire was used in 48 patients, and for the other group, tension band wiring was used in 40 patients. The average follow-up periods were 14 months in screw fixation group and 13 months in tension band wiring group. The average union time were 15.4 weeks (8-17 weeks) in screw fixation group and 12.2 weeks (6-15 weeks) in tension band wiring group. 27 cases (56%) showed excellent result in screw fixation group and 30 cases (75%) in tension band wiring group. In the patient over 50 years old, 2 (15%) in 13 cases showed excellent result of screw fixation group, while 5 (45%) in 11 cases of tension band wiring group. We concluded that tension band wiring is a better method for medial malleolar fracture to obtain early union and to prevent postoperative complications, especially in the elderly patient.
