Danis-Weber classification

Description

The Danis-Weber classification is a method of describing ankle fractures. It has three categories, based primarily upon the fracture of the fibula:

  • Type A. Fracture of the fibula distal to syndesmosis. An oblique medial malleolus fracture may also be present.
  • Type B. Fracture of the fibula at the level of the syndesmosis. These fractures may be stable or unstable, based upon the presence of deltoid ligament rupture or medial malleolus fracture.
  • Type C. Fracture of the fibula proximal to syndesmosis. These unstable fractures are generally associated with syndesmosis injuries, and may include medial malleolus fracture or deltoid ligament rupture.
