v4.1 Fusion X
Hawkins classification I–IV based on displacement/dislocation. AVN risk increases with stage: I 90%. Urgent reduction and fixation critical to preserve talar blood supply. Fixation: screws/plates, often dual incision approach. Hawkins sign (subchondral lucency) = revascularization on X-ray at 6–8 weeks.
