Closed posterior ankle dislocation without associated fractures: a case report.

Ankle dislocation without associated fractures, also known as pure ankle dislocation is a rare injury. It is usually the result of high energy trauma. It could be a combination of predisposing anatomical factors plus certain ankle position at time of injury that produce this peculiar injury. In most cases it is managed conservatively with urgent reduction, 6-9 weeks of immobilization followed with intense physiotherapy. The outcome after these injuries is generally good where most of the patients in reported cases managed to return to the preinjury level of activity.
