Bimalleolar ankle fracture

Case contributed by Andrew Dixon
Diagnosis certain

Presentation

Inversion injury

Patient Data

Age: 30 years
Gender: Male
x-ray

Unstable Weber B fracture of the right distal fibular and fracture of the medial malleolus (bimalleolar ankle fracture).  Associated soft tissue swelling.

x-ray

Internal fixation of the bimalleolar fracture with lateral plate and screw fixation of the distal fibular and screws stabilizing the medial malleolus fracture. Unfortunately the distal tibiofibular syndesmosis is too wide (lack of tibiofibular overlap) and this ankle will probably be unstable unless a syndesmotic screw is added. 

Case Discussion

Unstable Weber B fracture of the right distal fibular and fracture of the medial malleolus (bimalleolar ankle fracture) with subsequent internal fixation that failed to recognize a syndesmotic injury.
