Danis–Weber classification

Danis–Weber classification of ankle fractures (Types A, B and C)

The Danis–Weber classification (often known just as the Weber classification) is a method of describing ankle fractures. It has three categories:[1]

Type A

Fracture of the lateral malleolus distal to the syndesmosis (the connection between the distal ends of the tibia and fibula).

Type B

Fracture of the fibula at the level of the syndesmosis

Type C

Fracture of the fibula proximal to the syndesmosis.

Categories B and C imply a degree of damage to the syndesmosis itself (which cannot be directly visualised on X-ray). They are inherently unstable and are more likely to require operative repair to achieve a good outcome. Type A fractures are usually stable and can be managed with simple measures, such as a plaster of paris cast.
