Ligaments of the foot (medial view) (English)

From this medial perspective, the plantar calcaneonavicular ligament (a.k.a. spring ligament) is of particular interest. It extends between the sustentaculum tali and medioplantar margin of the posterior surface of the navicular bone, filling a wedge-shaped gap between these structures. It functions to stabilize the medial longitudinal arch of the foot and supports the head of the talus within the talocalcaneonavicular joint.Also visible is the long plantar ligament which extends from the plantar surface of the calcaneus to the cuboid and second-fourth/fifth metatarsal bones. It supports the transverse tarsal joint and longitudinal arches of the foot.
