Description

Topic Introduction

Ankle Fracturs Lauge-Hansen Classification Lauge-Hanse is a 2-word ankle fracture classification system that is based on 1st word> position of foot during time injury: foot can be - Pronated: eversion, abduction, dorsiflexion>> here the medial ligament is fully stretched> more susceptible to injury - Supinated: inversion, adduction, plantarflexion>> here the lateral ligaments are fully stretching 2nd word> is the movement of the talus bone in relation to the tibia >> the movement of the talus is actually what causes the injury as its movement affects the surrounding architecture. It can be: - Inverted - Everted - Laterally rotated

There are 4 main classifications in Lauge-Hansen 1) Pronation + Abduction (PAB) > foot is fixed in pronation and a force causes talus to evert/abduct. There are 3 stages in PAB. In stage 2 anterior and posterior tibiofibular ligaments. Stage 3 aka butterfly fracture

2) Pronation + External rotation (PER)> foot is fixed pronated position and a force causes the talus to go laterally. There are 4 stages in PER. Stage 3 includes proximal fibular spiral fracture. Stage 4 affects the tibiofibular ligament

3) Supination + Adduction SAD> inversion of talus with fixed supination. There are 2 stages.

4) Supination + External rotation SER> this is by far the most common type of injury. Foot is fixed is in fixed supinated position and injury to talus causes it to move laterally. The difference between PER and SER is the level of the fibular fracture which tends to be lower down near the ankle joint...
