The trimalleolar fracture is rare in the malleolar fractues of the ankle. Since 1964, we have examined 17 cases of the trimalleolar fractures. The causes of them were as follows:
Traffic Accident…7
Blow…7
Fall…2
Un-known…1
Frequent complication of the tear of the tibiofibular ligament and the subluxation of the talus are shown on these type of fractures. All cases were treated under the open operation. The flagments were fixed with the screw; the repair of the tear on the tibiofibular ligaments were treated with the tibial bolt.
The flagments should be lined up as well as possible. Otherwise, sooner or later with the motion and weight-bearing, the ankle develops severe traumatic arthritis.
