Ankle and foot joints

In A the talus (5) is embraced by the lateral and medial malleoli (1 and 4) and the lower end of the tibia, giving a very evenly-spaced ankle joint line (3).

The lateral view in B shows the tarsal sinus (6) between the talus and calcaneus, with the talocalcaneal joint (7) behind the sinus and the talocalcanean part (9) of the talocalcaneonavicular joint in front of it. The talonavicular part of the talocalcaneonavicular joint is in front of the head of the talus (8). Behind the cuboid (13) is the calcaneocuboid joint (12), and in front of it the articulations with the fourth and fifth metatarsals (15 and 16). Below the cuboid is a small (occasional) sesamoid bone in the tendon of fibularis (peroneus) longus (14).

Compare the metatarsals and sesamoid bones in C and D with those on p. 44 .
