A case of dislocation fracture of the calcaneus is reported. A-32-year-old man fell from the carrier of his truck. Roentgenograms and CT scan were performed for diagnosis. The lateral calcaneal fragment was dislocated at both the talocalcaneal and calcaneocuboid joints. Closed reduction for dislocation could be performed easily. Instability was not recognized after reduction. Open reduction and internal fixation with kirschner wires (k-wires) were performed to reduce the talocalcaneal joint.
Four weeks, later k-wires were removed, and partial-weight-bearing was started using foot sole brace. Weight-bearing increased gradually, and the brace was removed after ten weeks.
Nine months later, he experienced pain while he was working. Pseudoarthrosis of sustentaculum tali was recognized on CT image.
