Ankle fractures

Ankle fractures are commonly a low-energy fracture of either the lateral or medial malleolus, or both, and can include a fracture of the posterior malleolus.

Vascular compromise is rare and is usually the result of fracture-dislocations.

Proper immobilization, analgesia, and timely orthopedic referral as appropriate can greatly enhance patient comfort and ensure optimal outcome. Some nondisplaced or anatomically reduced ankle fractures can be treated conservatively, but consult with an orthopedist is generally recommended.

Displaced fractures are commonly treated with an open reduction and internal fixation.

Open fractures require emergency treatment by experienced surgeons including saline irrigation, wound debridement, and removal of all devitalized tissue and foreign debris.

The term "ankle fracture" most commonly refers to fracture types in which one or more of either the medial, lateral, or posterior malleolus is broken. It may be associated with dislocation of the ankle joint. Maisonneuve fracture is a high fracture of the fibula with a concomitant separation of the tibiofibular syndesmosis and fracture of the medial malleolus or rupture of the medial ankle ligament complex, essentially representing a dissociation of the tibia and fibula below the level of the fibula fracture.[1]Inokuchi R, Jujo Y, Iwashita K, et al.
