Ligaments of Ankle and Foot

Question 1

Lateral ligaments of the ankle:

Posterior talofibular

Answer 1

Attachments- malleolar fossa of the fibula to the lateral
tubercle of the talus

Function – restrict talocrural inversion

Question 2

Lateral ligaments of the ankle:

Calcaneofibular

Answer 2

Attachments – tip of the lateral malleolus to the lateral surface of the calcaneus

Function – resist calcaneal/subtalar inversion

Question 3

Lateral ligaments of the ankle:

Anterior talofibular

Answer 3

Attachments - anterior lateral malleolus of the fibula to the neck of the talus

Function – resist talocrural inversion and resist anterior translation of the talus

Question 4

Long plantar

Answer 4

attachments- from the plantar surface of the calcaneus & cuboid to the plantar surface of the bases of the metatarsals

Question 5

Plantar calcaneocuboid (aka “short plantar lig.”)

Answer 5

attachments- from calcaneus to the plantar surface of the cuboid

Question 6

Plantar calcaneonavicular (aka “spring lig.”)

Answer 6

attachments- from the anterior margin of the sustentaculum tali to the plantar surface of the navicular

function- supports the medial longitudinal arch of the foot

Question 7

Talocrural fibrous capsule

Answer 7

attachments- from the borders of the articular surfaces of tibia & malleoli to the margins of the trochlear surface of the talus

Question 8

Medial collateral (deltoid)

Answer 8

attachments- from the medial malleolus to the talus, navicular & sustentaculum tali of the calcaneus

function- stabilizes joint – resists talocrural and subtalar eversion
