Danis–Weber classification

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

Category A

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

  • below level of the ankle joint
  • tibiofibular syndesmosis intact
  • deltoid ligament intact
  • medial malleolus often fractured
  • usually stable : occasionally nonetheless requires an open reduction and internal fixation (ORIF)
Category B

Fracture of the fibula at the level of the syndesmosis

  • at the level of the ankle joint, extending superiorly and laterally up the fibula
  • tibiofibular syndesmosis intact or only partially torn, but no widening of the distal tibiofibular articulation
  • medial malleolus may be fractured or deltoid ligament may be torn
  • variable stability
Category C

Fracture of the fibula proximal to the syndesmosis.

  • above the level of the ankle joint
  • tibiofibular syndesmosis disrupted with widening of the distal tibiofibular articulation
  • medial malleolus fracture or deltoid ligament injury present
  • unstable : requires ORIF

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.
