What are the plantar ligaments?
• Are Accessory ligaments • Short plantar ligament • (plantar calcaneocuboid) • Between calcaneus and cuboid • Long plantar ligament • Between calcaneus and metatarsals 2-4 (via cuboid) • Plantar calcaneonavicular “spring” ligament – (medial side) • Between sustentaculum tali of calcaneus and navicular • Strong but NOT elastic • Bifurcate ligament – (lateral side) • Calcaneus – navicular (medial) Calcaneus – cuboid (lateral)

Arteries: Dorsalis pedis (Anterior Tibial)
What are the plantar nerves and arteries of the foot?
Nerves: Tibial, sural, saphenous
Arteries: Plantar (Posterior Tibial)
