HAWKINS SIGN
◾The Hawkins sign describes subchondral lucency of the talar dome seen in AP view that occurs secondary to subchondral atrophy 6-8 weeks after a talar neck Fractures.
◾This indicates that there is sufficient vascularity in the talus, and is therefore unlikely to develop avascular necrosis of the talar dome later.
◾Disruption of the blood supply to all or a portion of the talar dome results in absence of the Hawkins sign (seen as subchondral sclerosis), which usually indicates underlying avascular necrosis.
