Talus bone

Talus bone

The talus or talus is the lower part of the foot; its fifth and only bone part (the other four are tendons). It has a round head - the talar articular surface - for connection with the second phalanx of the thumb. The head of the talus is a sesamoid bone and is connected to its body by the triceps surae tendon, which attaches to the calcaneal tubercle. Thus, the talus acts as a kind of intermediate support for the head. The second ends of the bone correspond to two fossae of the foot - notches in the bases of the II and III fingers. Under the talus runs the tarsal groove, rich in vessels that reach the muscle bundles of the foot. The peripheral vessels of the foot pass along this groove, which diverge from the artery of the foot to the toes. There are five types of talus bone: I. Normal talus: its head is the largest. It is usually defined as the ram of the first toe. This is a normal ram if its length corresponds to the size of the foot and leg of an adult. II. Subocclusal ram. Its head is significantly smaller than its body. Instead of the calcaneal tubercle, there is a protruding muscular process called the lateral plantar stripe. III. The lateral flat-footed ram is a type of subocclusal ram; has an irregular wedge-shaped appearance. IV. Camel ram. Due to the slope of its outer surface, their asymmetry is revealed. V. Sardonically removed ram (“eternal “heel”). This is when the ram is outside the foot. Wedge-shaped protrusion
