Overview[1][2]

The Lauge-Hansen classification system is named after Sir Niels Lauge-Hansen, a Danish physician, who worked on ankle fracture mechanisms in 1940 - 1950.

Lauge-Hansen classification

Grade Sequence
Supination-Adduction Stage 1: With no medial malleolar fracture (Weber A)

Stage 2: With oblique or vertical medial malleolar fracture

Supination-External rotation

(40-70% of injuries)

Stage 1: Tear or avulsion of the anteroinferior tibiofibular ligament is torn or avulsed

Stage 2: The talus displaces and fractures the fibula in an oblique or spiral fracture, starting at the joint (Weber B)

Stage 3: Tear of the posteroinferior tibiofibular ligament or fracture posterior malleolus

Stage 4: Tear of the deltoid ligament or transverse avulsion fracture medial malleolus

Pronation-Abduction stage 1: Deltoid ligament disruption or transverse medial malleolus fracture

stage 2: Posterior malleolus fracture

stage 3: Oblique fibular fracture (Weber C)

Pronation-External rotation stage 1: Deltoid ligament rupture, which may appear occult or as medial mortise widening, or  transverse avulsion fracture of the medial malleolus

stage 2: Involvement of the AITFL with extension into the interosseous membrane results in widening of the distal tibiofibular distance

stage 3: A spiral or oblique fibular fracture (>6 cm) at the level or above the talotibial joint (Weber C) stage 4: Involvement of the posterior inferior tibiofibular ligament (PITFL), or posterior malleolus fracture
