1. Ankle Ligaments
http://www.footcarewindsorlasalle.com/orthoticswindsor.html

2. Introduction
□ Ankle joint:
□ hinge-type synovial joint
□ distal ends of tibia and fibula
□ superior part of talus
□ malleolar mortise
□ Stable during dorsiflexion
□ Unstable during plantar flexion

4. Medial Ligaments of Ankle
Deltoid ligament:
□ Two deep bands:
□ anterior tibiotalar ligament
□ tibionavicular ligament
□ Two superficial bands:
□ tibiocalcaneal ligament
□ posterior tibiotalar ligament

5. Deep Deltoid Ligaments
□ Anterior tibiotalar ligament
□ from medial malleolus to anteromedial side
of talus
(McAlindon, n.d.)

6. Deep Deltoid Ligaments
□ Tibionavicular ligament
□ from medial malleolus to navicular tuberosity
(McAlindon, n.d.)

7. Superficial Deltoid Ligaments
□ Tibiocalcaneal ligament
□ from medial malleolus to sustentaculum tali
of calcaneus
(McAlindon, n.d.)

8. Superficial Deltoid Ligaments
□ Posterior tibiotalar ligament
□ from medial malleolus to postermedial side of
talus
(McAlindon, n.d.)

9. Medial Ligaments of Ankle
□ Limits eversion of the foot at the
subtalar joint
□ Limits dorsiflexion at the subtalar joint
□ Limits plantar flexion at the subtalar
joint (anterior tibiotalar ligament)

11. Lateral Ligaments of Ankle
□ Ankle joint is reinforced laterally by
three ligaments:
□ anterior talofibular
□ posterior talofibular
□ calcaneofibular
(Shannon, 2004)

12. Anterior Talofibular Ligament
□ Lateral malleolus to the neck of the talus
□ Flat and weak band
□ Most commonly injured during ankle sprains
(Ellis & Henderson, 1994)

13. Posterior Talofibular Ligament
□ Malleolar fossa of fibula to the lateral
tubercle of the talus
□ Thick and strong band
(D. Tyczynski, APCH 111 lecture, November 6, 2008)

14. Calcaneofibular Ligament
□ Tip of lateral malleolus to lateral
surface of calcaneus
□ Round cord
□ Often torn
(eOrthopod, n.d.)

15. Lateral Ligaments of Ankle
□ Dorsiflexion:
□ limited by anterior talofibular ligament
□ Plantarflexion:
□ limited by calcaneofibular ligament and
posterior talofibular ligament

16. Conclusions
Body parts most often injured in sport:
□ ankles 12%
□ fingers 10%
□ face 9%
□ Highest in basketball, ice skating &
soccer

17. Conclusions
Most frequent injuries diagnosed:
□ sprains/strains 29%
□ fractures 21%
□ abrasions 20%
Ankle sprains:
□ When motion of talus exceeds the limits of
the joint-supporting ligaments
□ Results in a stretch, tear or complete rupture
of one or more of these ligaments
□ Inversion, eversion, syndesmotic
