Successful management of open talar and calcaneal injuries of the hindfoot is a formidable orthopaedic challenge. The soft-tissue disruption associated with these high-energy traumatic injuries adds to treatment complexity. Extensive fracture comminution and cartilage damage are often present with calcaneal fracture. ⋯ Long-term outcomes are frequently unsatisfactory. Chronic ambulatory dysfunction and persistent neurogenic pain may result despite appropriate management. With severe complex open fractures and extended soft-tissue injury, limb amputation may be the best treatment option.

Ankle syndesmotic injury does not necessarily lead to ankle instability; however, the coexistence of deltoid ligament injury critically destabilizes the ankle joint. Syndesmotic injury may occur in isolation or may be associated with ankle fracture. In the absence of fracture, physical examination findings suggestive of injury include ankle tenderness over the anterior aspect of the syndesmosis and a positive squeeze or external rotation test. ⋯ Fixation of the syndesmosis is indicated when evidence of a diastasis is present. This may be detected preoperatively, in the absence of fracture, or intraoperatively, after rigid fixation of the medial malleolus and fibula fractures. Failure to diagnose and stabilize syndesmotic disruption adversely affects outcome.
