title: External fixation of open subtalar dislocation.
abstract: Subtalar dislocation is a rare and severe injury, caused by high-energy trauma such as fall from a height or traffic accident. Infection and avascular necrosis are not rare sequelae of open subtalar dislocation, and the outcome may be poor. External fixation allows complete wound care, and moderate distraction of the ankle joint should unload the talus, which may reduce the risk of avascular necrosis. We treated 11 open subtalar dislocations by distractional external fixation. The series involved nine males and two females, of average age 30.39 years. In nine cases the injury was caused by falling from a height, and in two by a traffic accident. The follow-up period ranged from 18 to 28 months. The final functional results were good, with no infection and one case of avascular necrosis of the talus. Pain after a longer period of walking or standing was experienced by eight patients, and movement of the subtalar joint was limited in nine patients. Immediate distractional external fixation of open subtalar dislocation may prevent infection and avascular necrosis of the talus.
