Foot/ankle

The foot can be subdivided into the hind foot, the midfoot, and the forefoot. The hind foot is composed of the ankle bone and heel bone. The two long bones of the lower leg, the tibia and fibula, are connected to the top of the talus to form the ankle. A firm fascia around the ankle and the foot provides stability. The five irregular bones of the midfoot, the cuboid, navicular, and three cuneiform bones, form the arches of the foot which serves as a shock absorber. The midfoot is connected to the hind- and fore-foot by muscles and the plantar fascia.

The forefoot is composed of five toes and the corresponding five proximal long bones forming the metatarsus. The instep is the arched part of the top of the foot between the toes and the ankle.

Due to their complex construction, position and function, feet are exposed to a variety of potential infections and injuries.
