Talushalsfrakturen
AchtungDie ursprünglich 3 teilige Klassifikation der Talushalsfrakturen wurde von Canale und Kelly 1978 um "Group 4" ergänzt.  

Group 1Undisplaced vertical fracture of the neck of the talus: The fracture enters the subtalar joint between the middle and posterior facets. Frequently a portion of the fracture line will enter the body involving the posterior facet of the subtalar joint or the anterior most portion of the articular cartilage of the talus. The body of the talus remains its normal position in the ankle and subtalar joint 
 Group 2Displaced vertical fracture of the neck of the talus: Subtalar joint subluxated or dislocated, the ankle joint normal. The fracture line frequently enters a portion of the body and posterior facet of the talus 
 Group 3Displaced vertical fracture of the neck of the talus: The body of the talus is dislocated from both the ankle and subtalar joint. Fracture line frequently enters a portion of the body of the talus. The body is often extruded posteriorly and medially, being located between the posterior surface of the tibia and the Achilles tendon. Frequently the body of the talus rotates within the ankle mortise and became wedged in varying positions between the tibia and the calcaneus. The head of the talus usually remains in normal relationship with the navicular. The three main sources of blood supply to the body of the talus are damaged in this injury
