Isolated distal fibula fractures account for up to 55-65% of all ankle fractures.
Isolated distal fibula fractures account for up to 55-65% of all ankle fractures. There are many different classifications used for these fractures. For the purpose of this review, we will use the Danis-Weber criteria for lateral fibula fractures.
The Weber criteria relates the position of the distal fibula fracture to the syndesmosis. The other criteria commonly used is the Lauge-Hansen classification. This criteria is based upon the position of the foot at the time of the injury, which is typically in a supination-external rotation position.
Weber classification of distal fibular fractures (courtesy of faculty.washington.edu) In order to discuss treatment of these fractures, it is important to understand the anatomy of the ankle joint. Outside of the bones, which include the talus, medial malleolus, lateral malleolus, and tibia plafond, there are three ligamentous groups that provide support to the ankle. The medial ankle is supported by the deltoid ligament.
The lateral ankle is supported by the anterior talofibular, calcaneofibular, and posterior talofibular ligaments. There is also the syndesmosis which connects the distal tibia and fibula. The syndesmosis includes the interosseous ligament, anterior inferior tibiofibular ligament, inferior transverse ligament, and posterior inferior tibiofibular ligament.
Weber A A Weber A fracture typically occurs during an inversion ankle injury. Weber A fractures occur below the syndesmosis. These fractures are typically associated with a stable ankle joint.
If you are experiencing symptoms that may be related to a distal fibula fractures, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
