Results: No Hawkins sign was found in the five patients who developed avascular necrosis AVN of the talus. In the remaining 26 patients who did not develop AVN, a positive full Hawkins sign was observed 11 times, a partially positive Hawkins sign 4 times, and a negative Hawkins sign 11 times. The Hawkins sign if present appeared between the 6th and the 9th week after trauma. The clinical results were satisfactory. Conclusion: The Hawkins sign is a good indicator of talus vascularity following fracture.

Loading more images Objective To assess if the Hawkins sign can predict whether or not astragalus fractures of the neck will develop avascular necrosis. The results were compared with those found in the literature. Material and methods A retrospective study was conducted on 23 talar neck fractures recorded over a period of thirteen years. The following variables were analyzed: displacement of the fracture, soft tissue injury, delay and type of treatment, complications, observation of the Hawkins sign, and functional outcome.
Conclusion A positive Hawkins sign rules out that the fractured talus has developed avascular necrosis, but its absence does not confirm it. Palabras clave:. Texto completo.
