Ankle fracture - Weber B3
Weber ankle fracture is an easy system to classify lateral malleolar fractures in relation to the ankle joint.
Classification:
Type A: below the level of the talar dome. Tibiofibular syndesmosis intact. Usually stable if medial malleolus intact.
Type B: distal extent at the level of the talar dome & may extend some distance proximally. tibiofibular syndesmosis usually intact but widening of the distal tibiofibular joint may be seen. Variable stability. Subtypes:
B1: isolated
B2: associated with a medial lesion in (malleolus or ligament)
B3: associated with a medial lesion and fracture of posterolateral tibia (as in our case)
Type C: above the level of the ankle joint with disruption of tibiofibular syndesmosis with widening of the distal tibiofibular articulation. Unstable: usually requires ORIF. Subtypes:
C1: simple diaphyseal fracture of the fibula
C2: complex diaphyseal fracture of the fibula
C3: proximal fracture of the fibula
