Abstract
Malunion after a malleolar fracture can include a displaced posterior malleolus with associated posterolateral subluxation of the talus. Corrective osteotomy including the posterior malleolus was performed in four patients. Joint congruity was obtained in every case. The patients were followed for 46 to 80 months postoperatively. They all experienced an improvement in pain and three of four patients were unlimited in their walking capacity. Mild to moderate residual symptoms were frequent. The symptoms were attributed to the damage of the cartilage and soft-tissues both from the initial injury and from weightbearing on the incongruous joint. Discrete, non-progressive osteophytes were seen in all patients. Delay in reconstruction did not preclude a good result, although early reoperation is felt to be preferable.
