Lateral talocalcaneal ligament

The lateral talocalcaneal ligament (LTCL) is a short, strong bundle of muscle fibers found in the human ankle. The lateral talocalcaneal ligament stretches from the lateral portion of the talus to the lateral surface of the calcaneus. It is located parallel to the calcaneofibular ligament. The lateral talocalcaneal ligament's name was derived from the Latin ligamentum talocalcaneum laterale. The lateral talocalcaneal ligament can only be viewed by removing the talus bone. Injuries to the ankle ligaments are extremely common, particularly in athletes. The lateral process of the talus extends from the lateral portion of the talus bone. It is comprised of two articular facets, the dorsolateral and the inferomedial. The lateral process is the location where the lateral talocalcaneal ligament is inserted into the bone. Fractures in this area of the ankle are quite common, as no muscles originate in the talus, nor do they connect to the talus bone. The lateral process of the ankle is comprised solely of bone and cartilage. Injuries to the lateral process can be difficult to view using traditional diagnostic imaging studies.
