Radiology · Musculoskeletal imaging: Maisonneuve fracture

Sample item

After a twisting ankle injury a patient has medial ankle tenderness and a widened medial clear space, but ankle radiographs show no fibular fracture. There is marked tenderness over the proximal fibula. What injury is this?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Maisonneuve fracture

A Maisonneuve injury combines a proximal fibular fracture with disruption of the syndesmosis and the interosseous membrane and a medial malleolar fracture or deltoid rupture. The ankle films can look near normal, so the full length of the fibula must be imaged. It is unstable and usually needs surgery.

Option by option

  • A. Jones fracture

    A Jones fracture is at the base of the fifth metatarsal.

  • B. Maisonneuve fracture (correct)

    Correct. A proximal fibular fracture with medial injury and syndesmotic disruption is Maisonneuve.

  • C. Lisfranc injury

    A Lisfranc injury is a tarsometatarsal fracture-dislocation of the midfoot.

  • D. Weber A fracture

    A Weber A fracture is a transverse fibular fracture below the syndesmosis.
