What ligament is most commonly injured in lateral ankle sprains?
Anterior talofibular ligament
What percentage of lateral ankle sprains result in complete tear?
40%
What is a potential consequence of lateral ankle sprain in 40% of cases?
chronic ankle instability
What is the mechanism of injury for a lateral ankle sprain?
inversion force while weight- bearing
Which injury affects the anterior/ posterior tibiofibular ligaments and interossesous ligament
syndesmotic injury (high ankle sprain)
What motion causes a syndesmotic injury?
talus in lateral rotation and ankle dorsiflexion
Which ligament is injured in a medial ankle sprain?
deltoid ligament
What mechanism typically causes a medial ankle sprain
forced eversion and lateral rotation
What is a clinical sign of medial ankle sprain
asymmetrical and correctable flat foot
