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 |
