The anterior talofibular ligament (ATFL) of the musculoskeletal system is characterized by being the most commonly injured ligament in the ankle.
It is part of the ankle joint. It consists of fibrous dense regular connective tissue of collagen fibers.
Its unique structural feature is that it is the weakest lateral ligament. It is a flat and weak band that runs from the lateral malleolus to the neck of the talus.
The anterior talofibular ligament as well as all other bones, muscles, and ligaments of the body are derived of mesodermal origin in the embryo.
The function of the ATFL is to support the lateral ankle joint by connecting the talus and the fibula.
Common diseases include ligament tears/sprains and fractures.
Commonly used diagnostic procedures include clinical history, physical exam, and MRI.
It is usually treated with physical therapy and NSAIDs for sprains. Fractures and dislocations are often treated with surgery.
