Danis-Weber Classification of Ankle Fractures
The Danis-Weber classification system uses the position of the level of the fibular fracture in its relationship to its height at the ankle joint.
Type A: fracture below the ankle joint
Type B: fracture at the level of the joint, with the tibiofibular ligaments usually intact
Type C: fracture above the joint level which tears the syndesmotic ligaments.
