The lateral malleolus is found at the foot end of the fibula, of a pyramidal form, and somewhat flattened from side to side; it descends to a lower level than the medial malleolus. The medial surface presents in front a smooth triangular surface, convex from above downward, which articulates with a corresponding surface on the lateral side of ...
These leg bones have two prominences (the lateral and medial malleoli) that articulate with the talus. At the foot end, within the tarsus, the talus articulates with the calcaneus (heel bone) below, and with the curved navicular bone in front; together, these foot articulations form the ball-and-socket-shaped talocalcaneonavicular joint.
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 posterior talofibular ligament is a ligament that connects the fibula to the talus bone.It runs almost horizontally from the malleolar fossa of the lateral malleolus of the fibula to the lateral tubercle on the posterior surface of the talus. [1]
Fracture of both sides of the ankle with dislocation as seen on anteroposterior X-ray. (1) fibula, (2) tibia, (arrow) medial malleolus, (arrowhead) lateral malleolus. An ankle fracture is a break of one or more of the bones that make up the ankle joint. [20] Symptoms may include pain, swelling, bruising, and an inability to walk on the injured ...
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]
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. It is one of the lateral ligaments of the ankle and prevents the foot from sliding forward in relation to the shin.
The lateral cuneiform (also known as third cuneiform or external cuneiform) intermediate in size between the other two cuneiform bones, is also wedge-shaped, the base being uppermost. It occupies the center of the front row of the tarsal bones , between the intermediate cuneiform medially, the cuboid laterally, the navicular posteriorly and the ...
