Hawkins sign (talus)

Hawkins sign describes subchondral lucency of the talar dome that occurs secondary to subchondral atrophy 6-8 weeks after a talar neck fracture 1.

This indicates that there is sufficient vascularity in the talus, and is therefore unlikely to develop avascular necrosis later 2,3.

Disruption of the blood supply to all or a portion of the talar dome results in absence of the Hawkins sign (subchondral sclerosis), which usually indicates underlying avascular necrosis 4.

History and etymology

Named for Dr Leland G Hawkins, American orthopaedic surgeon.
