Osmosis video - Joints of the ankle and foot

The ankle is a hinge-type synovial joint that involves the distal ends of the tibia and the fibula, and the superior part of the talus. Foot joints are grouped into four major types, which are the intertarsal, tarsometatarsal, metatarsophalangeal, and interphalangeal joints.

The intertarsal joints are found between the tarsal bones, and include the subtalar joint, the talocalcaneonavicular, the calcaneocuboid, the cuneonavicular, the cuboideonavicular, and intercuneiform joints. Tarsometatarsal joints connect the tarsals to the metatarsals; whereas the metatarsophalangeal joints join the metatarsals to the proximal phalanges of the foot. Finally, the interphalangeal joints lie between the phalanges of the foot.
