Ligaments of the foot (plantar view) (English)

Right foot with long plantar ligament removed. The major plantar ligaments are the plantar calcaneonavicular ligament, the long plantar ligament and plantar calcaneocuboid ligament (a.k.a short plantar ligament). The latter of these extends between the anterior part of the plantar surface of the calcaneus to the plantar surface of the cuboid bone. It functions to stabilize the calcaneocuboid part of the transverse tarsal joint and supports the lateral longitudinal arch of the foot. Several smaller plantar intertarsal ligaments can be seen between the cuboid, navicular and cuneiform bones. Plantar tarsometatarsal ligaments stabilize the articulations between the cuneiform and cuboid bones with the bases of the metatarsal bones. The metatarsophalangeal and interphalangeal joints are strengthened by tight collateral ligaments, which prevent excessive range of movement in these joints.
