posterior talofibular ligament; The posterior talofibular ligament runs horizontally between the neck of the talus and the medial side of lateral malleolus calcaneofibular ligament; The calcaneofibular ligament is attached on the posteromedial side of lateral malleolus and descends posteroinferiorly below to a lateral side of the calcaneus.
The player receives a blow to the outside of the ankle, causing the ankle to roll inwards (so that the sole of the foot faces laterally). This damages the ligaments on the inside of the ankle and fractures the fibula at the point of contact (usually just above the tibiofibular syndesmosis).
The lateral talocalcaneal ligament (external calcaneo-astragaloid ligament) is a ligament in the ankle. It is a short, strong fasciculus , passing from the lateral surface of the talus , immediately beneath its fibular facet to the lateral surface of the calcaneus .
The deltoid ligament (or medial ligament of talocrural joint) is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus. The deltoid ligament supports the ankle joint and also resists excessive eversion of the foot. [1] The deltoid ligament is composed of 4 fibers:
The anterior talofibular ligament is a ligament in the ankle. It passes from the anterior margin of the fibular malleolus , passing anteromedially to insert at the lateral aspect of the talus at the talar neck , in front of its lateral articular facet.
The anterior border is rough, for the attachment of the anterior fibers of the deltoid ligament of the ankle-joint. The posterior border presents a broad groove, the malleolar sulcus, directed obliquely downward and medially, and occasionally double; this sulcus lodges the tendons of the tibialis posterior and flexor digitorum longus.
The calcaneofibular ligament is a narrow, rounded cord, running from the tip of the lateral malleolus of the fibula downward and slightly backward to a tubercle on the lateral surface of the calcaneus. It is part of the lateral collateral ligament, which opposes the hyperinversion of the subtalar joint, as in a common type of ankle sprain. [1]
Though it does not span the ankle joint itself, the syndesmotic ligament makes an important contribution to the stability of the ankle. This ligament spans the syndesmosis, i.e. the articulation between the medial aspect of the distal fibula and the lateral aspect of the distal tibia. An isolated injury to this ligament is often called a high ...
