Classification

The following types of ankle fractures are classified within the Lauge-Hansen system:

Grade SequenceExample Supination-Adduction Anterior talofibular ligament sprain or distal fibular avulsion fracture Vertical medial malleolus fracture and impaction of anteromedial distal tibia Supination-External rotation Anterior inferior tibiofibular ligament sprain Lateral short oblique fibular fracture (anteroinferior to posterosuperior) Posterior inferior tibiofibular ligament rupture or avulsion of posterior malleolus Medial malleolus transverse fracture or disruption of deltoid ligament Pronation-Abduction Medial malleolus transverse fracture or disruption of deltoid ligament Anterior inferior tibiofibular ligament sprain Transverse comminuted fracture of the fibula above the level of the syndesmosis Pronation-External rotation Medial malleolus transverse fracture or disruption of deltoid ligament Anterior inferior tibiofibular ligament disruption Lateral short oblique or spiral fracture of fibula (anterosuperior to posteroinferior) above the level of the joint Posterior inferior tibiofibular ligament rupture or avulsion of posterior malleolus See also Danis–Weber classification Herscovici classification
