TEACHING POINTS

1. To review ankle anatomy and mechanism of ankle injuries. 2. To present 3 step-approach to Lauge-Hansen classification which is easy and facilitates diagnosis of ankle injuries.

TABLE OF CONTENTS/OUTLINE

1. Ankle anatomy2. Ankle positon and injury mechanism (force direction)3. Lauge-Hansen classification4. Danis-Weber classification5. 3 step approach Look for "avulsion" - medial, lateral, or superior of the ankle mortise. Injury starts with avulsion (widening), which tells you either adduction, abduction, or external rotation injury Look for "fibular fracture" - below or above the ankle mortise. Level of fibular fracture tells you either adduction, abduction, or external rotation injury Staging matrix consists of ankle position and clockwise/counterclockwise progression Staging starts with an avulsion site and progresses with clockwise direction in adduction/abduction injury and with counterclockwise direction in external rotation injury on the right ankle 6.
