Talus
The structure indicated is the
talus bone of the foot.
The foot contains
three groups of bones:
- Tarsals
- Metatarsals
- Phalanges
The talus is one of
seven tarsal bones. There are three groups of tarsal bones:
- Proximal group
- Intermediate group
- Distal group
There are two bones in the proximal group of tarsal bones: the
talus and the
calcaneus. The calcaneus is the largest tarsal bone and forms the heel through its posterior projection. The talus articulates with the
medial malleolus of the
tibia and the
lateral malleolus of the
fibula to form the ankle joint. In addition, it articulates with two other tarsal bones: the
calcaneus inferiorly, and the
navicular anteriorly.
The talus consists of the following main components:
- Head: contains facets for articulation with navicular and calcaneus
- Neck
- Body: elevated trochlear surface articulates with inferior end of tibia
