The Maisonneuve fracture, described by Dr. Jules Germain François Maisonneuve in 18401, is a fracture of the proximal part of the fibula that is associated with an injury to the ankle. This is also known as a pronation-external rotation injury to the ankle that disrupts the medial ankle structures initially and propagates along the syndesmotic ligaments and interosseous membrane and then exits, with a resultant fracture in the proximal part of the fibula2. Many authors have described variations of this injury3-5. Levy et al. described a single case report of a medial malleolar avulsion injury that did not have a proximal fibular fracture, but there was disruption of the ankle syndesmosis and proximal tibiofibular dislocation4.
