A Maisonneuve fracture is caused by pronation and external rotation. It can be difficult to find, even if we get fixated on the ankle.

The patient may present with a complaint of rolling their ankle and ankle pain. Be vigilant for this type of injury. It is made of two main components:

  1. A spiral fracture of the proximal fibula
  2. An unstable ankle injury

This would result in a widening of the ankle joint due to distal tibiofibular syndesmosis and/or deltoid ligament disruption, or fracture of the medial malleolus.  Surgical Treatment is needed.
