Abstract

• Avascular necrosis was a frequent complication of the fracture of the neck of the talus. Hawkins described a subchondral radiolucency visible in the body of the talus six to eight weeks after fracture.
  This sign has proved to be a useful objective prognostic sign; the presence of this sign would not undergo avscular necrosis.
  In eleven patients, serial roetgenograms were examined for this phenomenon. The results were as follows:
  1. Six fractures that had the Hawkins sign did not undergo avascular necrosis.
  2. Also, we experienced two cases of partial Hawkins sign which developed the partial avascular necrosis.
• Key words: Avascular necrosis, Talar neck fracture
