The '''Danis–Weber classification''' (often known just as the '''Weber classification''') is a method of describing [[Medicine:Ankle fracture|ankle fracture]]s. It has three categories:<ref>{{cite book |last1=Mcrae |first1=Ronald |last2=Esser |first2=Max |title= Practical Fracture Treatment |year=2008 |edition= Fifth |isbn=978-0-443-06876-8 |page=382 }}</ref>

;Type A
Fracture of the fibula [[Biology:Anatomical terms of location#Proximal and distal|distal]] to the syndesmosis (the connection between the distal ends of the [[Biology:Tibia|tibia]] and [[Biology:Fibula|fibula]]). Typical features:
* below level of the ankle joint
* tibiofibular syndesmosis intact
* deltoid ligament intact
* medial malleolus occasionally fractured
* usually stable: occasionally nonetheless requires an open reduction and internal fixation (ORIF) particularly if medial malleolus fractured

;Type B
Fracture of the fibula at the level of the syndesmosis. Typical features:
* 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 may be torn
* variable stability

;Type C
Fracture of the fibula [[Biology:Anatomical terms of location#Proximal and distal|proximal]] to the syndesmosis. Typical features:
* 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

Categories B and C imply a degree of damage to the syndesmosis itself (which cannot be directly visualised on X-ray). They are inherently unstable and are more likely to require operative repair to achieve a good outcome. Type A fractures are usually stable and can be managed with simple measures, such as a plaster of paris cast.{{cn|date=August 2021}}
