Lateral collateral ligament of ankle joint
Ligaments of the ankle
From Wikipedia, the free encyclopedia
The lateral collateral ligament of ankle joint (or external lateral ligament of the ankle-joint) is a ligament complex of the ankle[1] collectively composed of three ligaments attached to the fibula:

Together, these liaments attach to the talus, talus, and calcaneus bones respectively, and help stabilize the lateral ankle.[2]
The anterior talofibular ligament is the most common ligament involved in an ankle sprain, and the weakest of the lateral collateral complex.[3]
Structure
Its components are:
The anterior talofibular ligament attaches the anterior margin of the lateral malleolus to the adjacent region of the talus bone. The most common ligament involved in an ankle sprain is the anterior talofibular ligament.
The posterior talofibular ligament runs horizontally between the neck of the talus and the medial side of lateral malleolus
The calcaneofibular ligament is attached on the posteromedial side of lateral malleolus and descends posteroinferiorly below to a lateral side of the calcaneus.
