The talus bone, which is one of seven tarsal bones, articulates with the tibia. The talus bone also articulates with the fibula.
Of the seven ankle bones within the tarsus group, the talus bone is the second largest. The specific location where the talus bone connects with the lower leg bones is called the head of the talus. Just below the talus bone is the calcaneus, or heel bone.
In human anatomy, an articulation is a joint. The talus bone and lower leg bones articulate at the ball-shaped ankle joint. The joint is held together by the interosseous membrane, a thick layer of connective tissue that also encases the full lengths of the tibia and fibula.
