Joints of the foot
/dʒɔɪnts/ /ʌv/ /ðʌ/ /fʊt/
1. [noun] joints of the ankle, foot and toe joints. See ankle joints in glossary. The two most important joints of the foot are the subtalar and transverse tarsal joints which allow for inversion and eversion of the foot. Subtalar joint (synovial joint): Located between the talus and the calcaneus which is stabilized by medial, lateral, and interosseous talocalcaneal ligaments. Transverse tarsal joint: The transverse tarsal joint is actually a combination of the following two joints: Talocalcaneonavicular joint (synovial joint): Located between the talus and the calcaneus and the navicular bones. It’s stabilized by the plantar calcaneonavicular ligament. Calcaneocuboid joint (synovial joint): Located between the front of the calcaneus and the posterior surface of the cuboid bone. It’s stabilized by the bifurcated ligament on the top, the long plantar ligament on the bottom, and the short plantar ligament, which is deep to (located underneath) the long plantar ligament. The remaining joints of the foot allow for a little movement of the foot and toes: Cuneonavicular joint (synovial joint): Located between the navicular bone and the three cuneiform bones. It is supported by dorsal and plantar cuneonavicular ligaments. It allows for some gliding movement. Cuboideonavicular joint: This fibrous joint is between the cuboid and navicular bones. It’s supported by dorsal, plantar, and interosseous ligaments. Tarsometatarsal joints (synovial joint): Located between the tarsal bones and the bases of the metatarsal bones. These joints are strengthened by dorsal, plantar, and interosseus ligaments. Intermetatarsal joints (synovial joints): Involve the bases of the metatarsal bones. All these joints are strengthened by dorsal, plantar, and interosseus ligaments. Metatarsophalangeal joints (synovial joints) : Located between the heads of the metatarsal bones and the bases of the proximal phalanges. They’re supported by plantar and collateral ligaments. They allow you to flex and extend your toes as well as move them apart and closer together. Interphalangeal joints (synovial joints) : These joints connect the phalanges and are strengthened by collateral and plantar ligaments, and they let you flex and extend your toes

Frequently Asked Questions
How do the subtalar and transverse tarsal joints work together to enable smooth foot movement during everyday tasks?
The subtalar joint, positioned between the talus and calcaneus, allows inversion and eversion, while the transverse tarsal joint—formed by the talocalcaneonavicular and calcaneocuboid joints—helps adjust foot position on uneven surfaces, facilitating dynamic balance.
How are smaller foot joints, like the tarsometatarsal and metatarsophalangeal joints, involved in everyday walking actions?
During walking, the tarsometatarsal joints help transfer weight from the heel to the toes, while the metatarsophalangeal joints support toe flexion and extension, contributing to balance and the smooth, coordinated movements needed for steps.
