Maisonneuve fracture associated with a bimalleolar ankle fracture-dislocation: a case report.

The Maisonneuve fracture consists of a proximal fibular fracture with associated syndesmotic ligament disruption and injury to the medial ankle structures. The accepted mechanism of injury is an external rotation force applied to the ankle with the foot in either supination or pronation. Because most Maisonneuve fractures involve complete syndesmotic disruption, operative treatment is usually indicated. A case report is presented of an unusual fracture pattern-i.e., that of a distal fibular fracture with lateral ankle dislocation associated with a Maisonneuve fracture. To our knowledge, only two other similar cases are reported in the English literature.
