摘要
距骨缺血坏死(AVN)是由多种原因引起的一种慢性缺血性疾病,疾病早期患者往往表现为局部疼痛与肿胀,随着病情进展,患者出现踝关节炎、距下关节炎及距骨关节面的塌陷,症状加重导致踝关节功能的丧失甚至出现畸形,给患者带来巨大困扰。恢复距骨的血供是治疗AVN的关键,但当距骨坏死面积大且出现明显解剖结构的改变而很难补救时,以牺牲踝关节功能达到减轻症状的关节融合术成为治疗距骨坏死的主要选择。
Avascular necrosis（AVN） of talus is a chronic avascular disease caused by a variety of reasons, and patients in early stage usually have local pain and swelling, which may progress into ankle arthritis, subtalar arthritis and joint surface subsidence, causing the loss of ankle function even deformity, which are great distress to patients. Restoring blood flow to the talus is the key to the treatment of AVN of talus, but when osteonecrosis area is large and significant anatomical changes emerge,joint arthrodesis has become the main choice of treatment of osteonecrosis to relieve pain at the expense of ankle function.
