Ankle Fractures

Classifications

1. Lauge-Hansen

  • Cadaveric study which relates the fracture pattern to an injury mechanism
  • The first word in the designation refers to the foot's position at the time of injury; the second word refers to the direction of the deforming force. 

  • ''eversion'' is a misnomer; it more correctly should be ''external'' or ''lateral'' rotation

Type of injury (foot position/direction of force)

Pathology

Supination/adduction
