Trimalleolar fracture

A Trimalleolar fracture (pronounced: tri-ma-lee-o-lar fracture) is a specific type of ankle fracture that involves the breaking of three specific bones in the ankle region. These bones include the medial malleolus, the lateral malleolus, and the posterior malleolus.

Etymology

The term "Trimalleolar fracture" is derived from the Latin words "tri" meaning three, and "malleolus" meaning little hammer. This is in reference to the three malleoli (plural of malleolus) of the ankle that are broken in this type of fracture.

Description

A Trimalleolar fracture is a severe injury that often results from high-energy events such as falls from a height, motor vehicle accidents, or sports injuries. It is characterized by the simultaneous fracture of the three malleoli of the ankle. This type of fracture is often associated with ankle dislocation and can lead to long-term complications such as post-traumatic arthritis if not properly treated.
