talus(tā′lŭs) plural.tali [L., ankle]
The ankle bone. It is an irregular, stubby cylinder and articulates with the tibia, fibula, calcaneus, and navicular bone. In front its head has a broad, rounded articular surface that meets the navicular bone. The body of the talus has a saddle-shaped articular surface on the top that meets the distal articular end of the tibia to form the main ankle joint; the outer side of the talus has a broad, convex articular surface that meets the lateral malleolus of the distal end of the fibula. On the bottom of the head and the body of the talus, there are two separate convex articular surfaces that meet the calcaneus (heel) bone. It was formerly called astragalus
