Question 6

Stability Ankle of Joint relies

Answer 6

Shape of the tibia, fibula and talus
Ligaments
Legs muscles
Effective propioception

Question 7

Talocrural Joint Stability (most stable)

Answer 7

Dorsiflexion
wider anterior part of talus is positioned b/w sital tibia and fibula

talus securely tibiofibular ligaments and interosseous membrane.

Question 8

Talocrural Less Stable Plantarflexed

Answer 8

In plantarflexion, narrower position posterior part of the trochlea is position b/w tibia and fiubla. talis is loose on mortise
