ANKLE (aka, talocurural joint): • A hinge-type synovial joint that allows for a wide range of movement. • Comprises the following bones: the tibia, fibula, and talus. 4 parts of deltoid (medial) ligament: • Tibionavicular ligament • Tibiocalcaneal ligament • 2 Tibiotalar ligaments, anterior and posterior, which attach to the tibia and talus. These ligaments prevent over-eversion and maintain the medial longitudinal arch of the foot. 3 parts of the lateral ligament: • Talofibular ligaments, posterior and anterior, which attach to the talus and fibula. • Calcaneofibular ligament, which connects the fibula and calcaneus. • Several additional joints are intrinsic to the foot, which permit movement along multiple axes. • An ankle sprain refers to tearing or stretching of the ligaments, which can result in swelling of the joint; because ligaments are poorly vascularized, sprains heal slowly.
