Calcaneus was the most commonly involved bone among the tarsal bone fracture. Many different methods have been tried for the treatment of fractures of the calcaneus in order to search for better results. But there is no general agreement on the treatment of the fracture of the calcaneus, especially involving the subtalar joint. From Jan. 1986 to Jan. 1990, 25 feet in 20 patients of calcaneal fractures involving the subtalar joint were treated by closed reduction & percutaneous pinning at the Dept. of Orthopedic Surgery, Chosun University Hospital and the results were as follows; 1. Of these intra-articular fractures, 15 fractures were tongue type and 10 fractures were joint depression type by Essex-Lopresti classification. 2. According to the Salama unit system, the results of treatment were excellent or good in 11 cases of 15 tongue types and 6 cases of 10 joint depression types. 3. The results were excellent in which reduction is achieved near anatomical reduction. 4. Even if the joint depression type fracture which is not severely comminuted, the treatment with closed reduction & percutaneous pinning is thought to be good method.
