Astragalus (Bone)

Generality

The talus, or talus, is one of the seven bones that make up the tarsus of the foot. Together with the metatarsal bones and the phalanges, the tarsal bones form the skeletal scaffolding of the human feet.

In the talus, anatomists recognize three portions: the head (in the distal position), the neck (in the intermediate position) and the body (in the proximal position).
The talus is one of the bony elements that participate in the formation of the talo-crural joint, also known as the ankle proper; the others are the calcaneus (another bone in the tarsus of the foot), the distal end of the tibia and the distal end of the fibula.
Minimally vascularized, the talus can fracture like any other bone in the human body.
