Flashcards in Ankle & Foot Region Deck (12):
0

Articulation of inferior surface of tibia with the trochlea of the talus

Dorsiflexion & plantar flexion of the foot

Ankle (talocrural) joint

1

From medial malleolus of the tibia to the talus, navicular & calcaneus bones

Consists of anterior tibiotalar, post tibiotalar, tibionavicular & tibiocalcaneal ligaments

Medial (deltoid) ligament

2

Form lateral malleolus of the fibula to the talus & calcaneus bones

Consists of anterior talofibular, posterior talofibular & calcaneofibular ligaments

Lateral ligament

3

Ankle (talocrural) joint contains the medial malleolus, related to the ff:

Medial malleolus is related anteriorly to the saphenous nerve & great saphenous vein

Medial malleolus is related posteriorly to the flexor hallucis longus, flexor digitorum longus & tibial posterior tendons; posterior tibial artery and tibial nerve

4

Articulation of the talus & calcaneus

Action: inversion & eversion of the foot

Subtalar joint

5

2 joints:
- talonavicular joint
- calcaneocuboid joint

Action: inversion & eversion of the foot

Transverse tarsal (Chopart) joint

6

Articulation of tarsal bones with the metatarsals

Tarsometatarsal (Lisfrane) joint

7

Occurs when foot is forcibly inverted, results in the ff injuries:
- stretch/tear of lateral ligament (most commonly the anterior talofibular ligament)
- fibular fracture
- avulsion of the tuberosity of 5th metatarsal (Jones fracture) where peroneus brevis muscle attaches

Inversion injury

8

Occurs when foot is forcibly everted, russets in the ff injuries:
- avulsion of medial malleolus
- fibular fracture

Eversion injury (Pott fracture)

9

Fracture of distal portion of tibia & fibula

Ski boot injury

10

Calcaneal (lover's) fracture

Jumping from a great height

Usually involves the subtalar joint

Associated with fractures of lumbar vertebrae & femoral neck

11

Lisfrane injury

Bicyclist's foot is caught in pedal clips

Fracture/dislocation at the tarsometatarsal (Lisfrane) joint
