ABSTRACT

Diagnosis: Weber Class C Ankle Fracture

History: 26 y/o male presented to Emergency Department with a swollen ankle after “slipping” on a gravel driveway.

Findings: Comminuted fracture of the distal shaft of the fibula and avulsion fracture of the posterior tibial malleolus with subluxation of the mortise joint. Soft tissue swelling noted posterior to the distal tibia and fibula.

Ddx: Ankle inversion injury, requiring classification in the Weber Ankle Classification System

Exam: Left distal lower extremity with swelling and pain on palpation. 2+ dp pulse. Skin intact. Patient unable to bear weight secondary to pain.

No MeSH data available.


Weber Type C fractures (see image C) are fibular fractures above the syndesmosis.  There is a deltoid-medial malleolus complex injury as well as an anterior tibiofibular ligament complex injury.  There may also be a posterior tibiofibular complex injury.Type C1: the interosseous membrane is intact and the fracture is low on the fibula.Type C2: the interosseous membrane is ruptured at the fracture site and the fracture is higher on the fibula.Type C3: the interosseous membrane is ruptured above the fracture site, creating instability of the fibula.
