The Frenchman's fibular fracture (Maisonneuve fracture).
Two patients with injuries to the ankle sustained by rotational trauma complained only of pain in the ankle. Careful examination revealed tenderness over the proximal fibula. Subsequent radiographic studies revealed high helical fracture of the fibula, as originally described by Maisonneuve. The Maisonneuve fracture is produced by diastasis - a separation of bones resulting from rupture of ligaments around the ankle. According to classification of fibula injuries by mechanism of injury, the Maisonneuve fracture is due to external rotation of the foot relative to the tibia but it is not clear whether the foot is in pronation or supination or moves during injury.
