Talus
The anklebone (talus) connects the foot with the leg. Its task is to transfer the forces generated by the body weight to the arch of the foot. It also forms the joint surface to the upper (Articulatio talocruralis) and lower ankle joint (Articulatio talotarsalis). It can be divided into two structures, the corpus tali and the ankle head (caput tali). On the upper side of the ankle bone there is a convex bone structure, the trochlea tali. Medial of this is the articular surface of the inner ankle (Facies malleolaris medialis). Lateral to this surface is a bony protrusion, the proc. posterior tali.
Lateral to the head of the ankle bone, the outer ankle is connected to the ankle bone via the lateral malleolar arteries. The proc. lateralis tali protrudes laterally from this surface. The joint surface for the scaphoid (Facies articularis navicularis) is located at the head of the ankle bone. The bone protrusion protruding backwards is called proc. posterior tali and is divided into two sections by the sulcus tendinis musculi flexoris hallucis longi. On the underside of the bone there are three joint surfaces, the facies articularis calcanea anterior, facies articularis calcanea media and facies articularis calcanea posterior. The articularis calcanea media and the articularis calcanea posterior are separated by the sulcus tali.
