Picture of the metatarsal (foot) and calcaneus (heel) bones, the plantar fascia ligament, and the Achilles tendon of the lower leg and foot
The ankle is a “hinged” joint capable of moving the foot in two primary directions: away from the body (plantar flexion) and toward the body (dorsiflexion). The meeting of three bones forms its anatomy. The end of the shinbone of the leg (tibia) and a small bone in the leg (fibula) meet a large bone in the foot, called the talus, to form the ankle. The end of the shinbone (tibia) forms the ankle’s inner portion, while the end of the fibula forms the outer part of the ankle. The hard, bony knobs on each side of the ankle are called the malleoli. These provide stability to the ankle joints, functioning as weight-bearing joints for the body during standing and walking.
