The ankle consists
of two joints: the subtalar joint, and the true ankle
joint.
The true ankle
joint is composed of 3 bones, the tibia which forms the inside
or medial side of the ankle; the fibula which forms the lateral,
or outside of the ankle; and the talus below.

The true ankle joint
is responsible for up and down motion of the foot.
Beneath the true ankle
joint is the second joint of the ankle, the subtalar joint, which consists
of the talus above and calcaneus below. The subtalar joint
allows side to side motion of the foot. The
ends of the bones in these joints are covered by articular cartilage
and are connected by various ligaments running through the foot.
