The os trigonum or accessory talus represents a failure of fusion of the lateral tubercle of the posterior process of the talus bone. Is estimated to be present in 7–25% of adults. [17] It can be mistaken for an avulsion fracture of lateral tubercle of talus (Shepherd fracture) or a fracture of the Stieda process. In most cases, Os Trigonum ...
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]
Figure to the right shows locations of rare accessory bones of the foot (presence variable from person to person): 1 = os cuneometatarsal I plantare, 2 = os uncinatum, 3 = os sesamoideum tibialis posterior, 4 = os sesamoideum peroneum, 5 = os cuboideum secundarium, 6 = os trochlear calcanei, 7 = os in sinus tarsi, 8 = os sustentaculum tali, 9 ...
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 five irregular bones of the midfoot—the cuboid, navicular, and ...
The posterior talocalcaneal articulation is formed by a concave surface of the talus and a convex surface of the calcaneus. [3] The sustentaculum tali forms the floor of middle facet, and the anterior facet articulates with the head of the talus, and sits lateral and congruent to the middle facet. In some people the middle and anterior facets ...
The deltoid ligament supports the medial side of the joint, and is attached at the medial malleolus of the tibia and connect in four places to the talar shelf of the calcaneus, calcaneonavicular ligament, the navicular tuberosity, and to the medial surface of the talus. The anterior and posterior talofibular ligaments support the lateral side ...
There are a total of 8 bones in the legs and 52 in the feet. Femur (2) Patella or kneecap (2) Tibia (2) Fibula (2) Foot (52 bones in total, 26 per foot) Tarsus. Calcaneus or heel bone (2) Talus (2) Navicular bone (2) Medial cuneiform bone (2) Intermediate cuneiform bone (2) Lateral cuneiform bone (2) Cuboid bone (2) Metatarsals (10)
Only one muscle is attached to the cuboid bone; the tibialis posterior.The tibialis posterior inserts to the under surface of the cuboid bone. [2] While the flexor hallucis brevis arises, by a pointed tendinous process, from the medial part of the under surface of the cuboid bone, from the contiguous portion of the lateral cuneiform bone, and from the prolongation of the tendon of the tibialis ...
