The ankle, the talocrural region [1] or the jumping bone (informal) is the area where the foot and the leg meet. [2] The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. [3] [4] [5] The movements produced at this joint are dorsiflexion and plantarflexion of the ...
It arises from the lateral condyle of the tibia; from the upper three-quarters of the anterior surface of the body of the fibula; from the upper part of the interosseous membrane; from the deep surface of the fascia; and from the intermuscular septa between it and the tibialis anterior on the medial, and the peroneal muscles on the lateral side.
The talus (/ ˈ t eɪ l ə s /; Latin for ankle [1] or ankle bone; [2] pl.: tali), talus bone, astragalus (/ ə ˈ s t r æ ɡ ə l ə s /), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. [3]
The dorsal ligaments are strong, flat bands.. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
The talus bone or ankle bone is connected superiorly to the two bones of the lower leg, the tibia and fibula, to form the ankle joint or talocrural joint; inferiorly, at the subtalar joint, to the calcaneus or heel bone. Together, the talus and calcaneus form the hindfoot. [1]
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 inferior tibiofibular joint, also known as the distal tibiofibular joint (tibiofibular syndesmosis), is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia.
The intertarsal joint are the joints of the tarsal bones in the foot. There are six specific inter tarsal joints (articulations) in the human foot: Subtalar joint; Talocalcaneonavicular joint; Calcaneocuboid joint; Cuneonavicular joint; Cuboideonavicular joint; Intercuneiform joints
