Ankle.
The ankle is a hinge joint formed by the junction of the tibia and fibula with the talus (ankle bone). The bones are cushioned by cartilage and connected by a number of ligaments, tendons, and muscles that strengthen the joint and enable it to be moved. Because it is in almost constant use, the ankle is particularly susceptible to injuries, such as sprain and fracture. It is also often one of the first joints to be affected by arthritis or gout.
tarsus (def. 2).
ankle cuff a weighted strip wrapped around the ankle and closed with a Velcro band; used during exercise.
