Ankle Fractures Danis Weber Classification


Ankle Fractures Danis Weber Classification

This classification is based on the level of fibular fracture. Fibular fracture that is more proximal indicates an increased risk of syndesmotic disruption and ankle instability.

Type A is an internal rotation and adduction injury. It is a fracture of the fibula below the level of tibial plafond. It is usually an avulsion injury from supination of foot. It may be associated with oblique or vertical medial malleolus fracture. Syndesmotic disruption is rare but can occur. This fracture resembles the supination/adduction injury in Lauge- Hansen classification. Type B is an oblique or spiral fracture of the fibula near or at the level of the syndesmosis. It is an external rotation injury. It may be an associated injury to the medial structures or the posterior malleolus. About 50% are syndesmotic injuries. This fracture probably resembles the supination/external rotation injury in Lauge- Hansen classification. Type C is an abduction injury. It is a fracture of the fibula above the level of syndesmosis. Syndesmosis disruption always occurs. There is an associated medial injury in almost all cases. It includes Maisonneuve fracture pronation/ abduction or pronation/ external rotation. In general, Type C ankle fracture simulates an abduction/ external rotation injury in Lauge- Hansen classification. Weber A is a Lauge Hansen supination adduction. Weber B is a Lauge Hansen supination/ external rotation. Weber C is a Lauge Hansen pronation/ external rotation.
