Maisonneuve Fracture


The Maisonneuve fracture is a spiral fracture of the upper third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane. There is an associated fracture of the medial malleolus or rupture of the deep deltoid ligament

Rupture of the stabilizing ligaments of the distal tibiofibular syndesmosis will result in widening of the ankle mortise on radiographs. Additional findings such as avulsion fracture of the medial or posterior malleoli, or tear of the deltoid ligaments may also be present

1840 – Maisonneuve described, using cadaveric studies, how an external rotation force applied to the foot could result in a fracture of the proximal third of the fibula

Associated Persons


  • In the case of an isolated medial malleolar fracture or medial ankle ligament rupture, a proximal fibula fracture (indicative of a rupture of the syndesmosis and interosseous membrane, should be excluded [J Emerg Med. 2013;44(2):e251-5]
  • Fracture of the proximal fibula as a result of a pronation external rotation or supination external rotation mechanism of the foot and ankle should be differentiated from an isolated fibula fracture caused by direct force transmission from the lateral aspect.
  • Maisonneuve fractures should be suspected whenever there is lateral talar displacement or tibiofibular widening without distal fibula fracture. Stress radiographs and full-length tibiofibular radiographs should be obtained
