Updates to Article Attributes
Body
was changed:
The Weber ankle fracture classification is a simple system for classification of lateral malleolar fractures, relating to the level of the ankle joint, and determining treatment.
-
type A
- 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)
-
type B
- 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 my be torn
- variable stability
-
type C
- 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
Etymology
