Maisonneuve fracture

Maisonneuve fracture is the combination of a spiral fracture of the proximal fibula and unstable ankle injury which could manifest radiographically by widening of the ankle joint due to distal tibiofibular syndesmosis and/or deltoid ligament disruption, or fracture of the medial malleolus. It is caused by pronation external-rotation mechanism. It requires surgical fixation. 5

Radiographic features

Plain radiograph

Ankle views may either show a fracture of the medial malleolus or widening of the ankle joint due to disruption of the distal tibiofibular syndesmosis (lateral talar shift) or deltoid ligament complex.

When these ankle injury types are seen, further imaging of the entire fibula is recommended to assess for an accompanying proximal fibular shaft fracture.

History and etymology

It is named after Jules Germain Francois Maisonneuve, French surgeon (1809-1897) 4.
