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 |
