NameOriginInsertionFunction
Lateral talocalcaneal ligament- Lateral process of talus- Lateral surface of calcaneum- Stabilise talocalcaneal joint (subtalar joint)
Medial talocalcaneal ligament - Medial tubercle of talus- Sustentaculum tali- Stabilise the talocalcaneal joint (subtalar joint)
Posterior talocalcaneal ligament - Lateral sinus taris of talus- Superior surface of calcaneum- Stabilise the talocalcaneal joint (subtalar joint)
Interosseous talocalcaneal ligament - Sinus taris of talus- Sulcus calcanei of calcaneus- Stabilise the talocalcaneal joint (subtalar joint)
Talonavicular ligament - Dorsal neck of talus- Superior part of navicular- Stabilise the talocalcaneonavicular joint
Plantar calcaneonavicular ligament - Anterior calcaneal tubercle- Plantar surface of navicular- Stabilise the talocalcaneonavicular joint
- Supports longitudinal foot arch
Dorsal Calcaneocuboid ligament (medial part of bifurcate ligament)- Anterior superior calcaneum- Dorsomedial part of cuboid- Stabilise the calcaneocuboid joint
Calcaneonavicular ligament (lateral part of bifurcate ligament)- Anterior superior calcaneum- Dorsolateral part of navicular- Stabilise the calcaneocuboid joint
Plantar calcaneocuboid ligament - Plantar surface of calcaneum- Plantar surface of cuboid- Stabilise the calcaneocuboid joint
- Supports lateral longitudinal arch
Long plantar ligament - Plantar surface of calcaneum- Plantar surface of cuboid
- Bases of metatarsals 2-5
- Stabilises the tarsal bones
- Main supporter of the lateral longitudinal arch
Plantar intercuneiform ligaments- Connect plantar surfaces
of adjacent cuneiform bones
- As origin describes- Stabilise the cuneiform bones and joints
Dorsal intercuneiform ligaments- Connect dorsal surfaces
of adjacent cuneiform bones
- As origin describes- Stabilise the cuneiform bones and joints
