Hawkin's classification of talar neck fractures
Hawkin's classification system divides fractures of the neck of talus into four types according to the degree of displacement and resulting risk of avascular necrosis. Higher type implies greater risk of complications.
| Type | Description | Subluxation | Avascular necrosis |
|---|---|---|---|
| Type I | Undisplaced fracture of talar neck | no | rare |
| Type II | Fracture of talar neck with mild displacement | subtalar joint | occasional |
| Type III | Fracture of talar neck with moderate displacement | subtalar and ankle joint | frequent |
| Type IV | Fracture of talar neck with severe displacement | subtalar, ankle and talonavicular joint | common |
