Trimalleolar fracture

Mr Andrew Murphy and Dr Ian Bickle et al.

Trimalleolar fractures refer to a three-part fracture of the ankle. The fractures involve the medial malleolus, the posterior aspect of the tibial plafond (referred to as the posterior malleolus) and the lateral malleolus. Having three parts, this is a more unstable fracture and may be associated with ligamentous injury.
