A Maisonneuve Fracture in an Active Duty Sailor: A Case Report

Maisonneuve fractures are relatively well known in the sports medicine, and orthopedic communities, however, can be commonly missed among primary care providers. The following case outlines an active duty 35-yr-old female patient who presented with acute pain on the left ankle and lower leg after she misjudged a step. The injury is a combination of high fibular and medial malleolar fractures with a disruption of the tibiofibular syndesmosis ligaments. This is a result of extreme external rotation and pronation of a fixed foot. The proper diagnosis is reliant on ankle and tibiofibular films, to include orthogonal views. This case serves as a reminder to always examine joints above and below the injury site, obtain orthogonal views of a fracture, as well as the unstable nature of syndesmosis injuries. This fracture is commonly a sports-related injury; thus, it is particularly important for military providers to be aware of Maisonneuve fractures and the common pitfalls in diagnosis and treatment.
