Balazsy MD Abstract Fractures of the talus are uncommon. The relative infrequency of these injuries in part accounts for the lack of useful and objective data to guide treatment. The integrity of the talus is critical to normal function of the ankle subtalar and transverse tarsal joints. Injuries to the head neck or body of the talus can interfere with normal coupled motion of these joints and result in permanent pain loss of motion and deformity. Outcomes vary widely and are related to the degree of initial fracture displacement. Nondisplaced fractures have a favorable outcome in most cases. Failure to recognize fracture displacement even when minimal can lead to undertreatment and poor outcomes. The accuracy of closed reduction of displaced talar neck fractures can be very difficult to assess. Operative treatment should therefore be considered for all displaced fractures. Osteonecrosis and malunion are common complications and prompt and accurate reduction minimizes their incidence and severity. The use of titanium screws for fixation permits magnetic resonance imaging which may allow earlier assessment of osteonecrosis however further investigation is necessary to determine the clinical utility of this information. Unrecognized medial talar neck comminution can lead to varus malunion and a supination deformity with decreased range of motion of the subtalar joint. Combined anteromedial and anterolateral exposure of talar neck fractures can help ensure anatomic reduction. Posttraumatic hindfoot arthrosis has been reported to occur in more than 90 of patients with displaced talus fractures. Salvage can be difficult and often necessitates extended arthrodesis procedures. J Am Acad Orthop Surg 2001 9 114-127 Major fractures and dislocations of the talus and peritalar joints are uncommon. However fractures of the talus rank second in frequency after calcaneal fractures of all tarsal bone .
