Peripheral talar fractures.

Peripheral fractures of the talus are uncommon and often overlooked. CT scanning has become the imaging modality of choice and is necessary for decision making on treatment. Displaced peripheral fractures have to be managed with open reduction and internal fixation. Precise anatomical reduction is necessary to achieve a good result. A rigid internal fixation with interfragmentary lag screws is the method of choice in almost all fractures, which allows early postoperative mobilization. The outcome is related to the degree of the chondral lesion and the degree of instability of the subtalar joint, but it may be poor due to the treatment. Early diagnosis and proper treatment achieve the best possible results and prevent long-term complications. Typical complications of the fracture are nonunion and malalignment with slight subtalar instability or osseous overgrowth with secondary impingement and posttraumatic subtalar arthritis.
