Ankle fracture -: Weber B3
Body was changed:

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. 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. 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

​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.

Updates to Study Attributes

Findings was changed:

Mildly displaced trimalleolar fracture with mild lateralisation of the talus suggesting ligamentous injury. The lateral malleolarfracture begins at the syndesmosis extending obliquely into the proximal part of the distal fibula.No widening of the distal syndesmosis.

No other fracture seen.Soft tissue oedema and haematoma around the fracture site.

Findings are consistent with Weber B3.
