Foot Bones and Joints

There are 28 bones in the foot, and over 30 joints. The bones in the foot include the five toe bones, called phalanges; five metatarsal bones in the body of the foot; three cuneiform bones, the cuboid bone and the navicular bone, which make up the arch of the foot; the calcaneus, or heel bone, which is the largest bone in the foot; and the talus bone, which supports the leg bones (tibia and fibula) where they form the ankle joint.

The ankle joint, called the tibiotalar joint is formed where the tibia meets the talus bone. Other joints in the back of the foot include the subtalar or talocalcaneal joint where the talus bone connects to the calcaneus, the talonavicular joint where the talus connects to the navicular bone, and the calcaneocuboid joint where the calcaneus meets the cuboid bone.

In the mid-foot are the metatarsocunieform joints, where the metatarsals meet the cuneiform bones. The metatarsophalangeal joints occur where the metatarsal bones meet the phalanges. The big toe joint, or first metatarsophalangeal joint can be prone to arthritis and it typically where bunions develop.
