Talar neck fractures and rates of avascular necrosis.

Talar neck fractures are unique and potentially debilitating injuries. Their successful treatment requires an understanding of talar anatomy and arterial blood supply, as well as knowledge of the sequelae of these injuries, particularly avascular necrosis of the talar body. Presented is an extensive literature review on talar neck fractures and Hawkins' classification, with special emphasis on the rates of avascular necrosis as determined by selected researchers on the topic.
