Posttraumatic Cavovarus Deformity Due to a Varus Malunited Talar Neck Fracture, Treated With Corrective Talar Osteotomy: A Case Report.

Although talar fractures are frequent bone injuries, fracture displacements of the talar neck are rare, and they can lead to under-treatment and poor prognosis. Furthermore, maltreatment of the talar fractures leads to complications such as malunion (which is the most common), nonunion, osteonecrosis and hindfoot arthritis, which can cause significant disability. The most common position of the talar neck malunion is the varus malunion. Alternative treatments include open reduction with or without bone grafting, open reduction combined with ankle fusion, talar neck osteotomy and talar neck osteotomy combined with subtalar fusion. However, the outcomes of foot function after corrective arthrodesis are poor. In this paper, we present a patient who underwent an open wedge corrective osteotomy of the talus for a cavovarus deformity developed after a malunion of a comminuted talar neck fracture. The patient walked normally three months postoperatively.
