Avascular necrosis of the talus has frequently been reported following trauma. The incidence of avascular necrosis has been reported to be as high as 50% for Hawkins Type II talar fractures and to range from 75-100% for Type III fracture-dislocations. The resultant avascular necrosis has been reported to occur primarily in the body and dome of the talus with apparent sparing of the head of the talus. The close association of trauma to avascular necrosis of the talus has been alluded to by Cobey and others. Reports of avascular necrosis of the talus, without an antecedent history of trauma, have been rare. This paper presents a case of atraumatic avascular necrosis of the talar head.
距骨缺血性坏死在创伤后屡有报道。据报道，霍金斯II型距骨骨折的缺血性坏死发生率高达50%，III型骨折脱位的发生率为75%-100%。据报道，由此导致的缺血性坏死主要发生在距骨体和距骨穹窿部，距骨头明显未受累。科贝等人提到了创伤与距骨缺血性坏死的密切关联。无创伤史的距骨缺血性坏死报道很少。本文介绍了一例距骨头非创伤性缺血性坏死的病例。
