Lauge Hansen classification of ankle fractures

Lauge-Hansen classification of ankle fractures is based on the mechanism of trauma. It describes position of the foot (supination or pronation) and the direction of the applied force (abduction, adduction, external rotation) at the time of the injury. Therefore, it uses two word description of its types. The five main groups can be subdivided into stages according to the degree of severity.

Type Abbrev. Weber equivalent
Supination-Adduction SA Weber A
Supination-Eversion (External Rotation) SE (SER) Weber B
Pronation-Abduction PA Weber C
Pronation-Eversion (External Rotation) PE (PER) Weber C
Pronation-Dorsiflexion PD Weber C
