Anterior talofibular ligament

Anterior Talofibular Ligament

The Anterior Talofibular Ligament (ATFL) is a ligament located in the ankle that connects the talus and the fibula. It is one of the most commonly injured ligaments in the ankle, often as a result of ankle sprains.

Anatomy

The ATFL is a short, flat, and weak ligament that runs from the anterior margin of the lateral malleolus to the neck of the talus, in front of its lateral articular facet. It is covered by the tendons of the Peroneus tertius and Extensor digitorum longus muscles.

Function

The ATFL restricts anterior displacement and internal rotation of the talus. It is the first ligament to be injured in an inversion sprain, which is the most common type of ankle sprain.

Injury

Injury to the ATFL, often in the form of a sprain, is common in sports and physical activities. The ligament can be strained, partially torn, or completely ruptured. Symptoms of an ATFL injury include pain, swelling, bruising, and difficulty moving the ankle.

Treatment

Treatment for an ATFL injury depends on the severity of the injury. Mild sprains can often be treated with rest, ice, compression, and elevation (RICE). More severe injuries may require physical therapy, a brace or cast, or surgery.
