UNASSIGNED: The recent domestic and international literature related to avascular necrosis of the talus was extensively conducted. The pathogenesis, surgical treatment methods, and prognosis were summarized.
UNASSIGNED: The clinical symptoms of avascular necrosis of the talus at early stage are not obvious, and most patients have progressed to Ficat-Arlet stages Ⅲ-Ⅳ and require surgical treatment. Currently, surgical treatments for this disease include core decompression, vascularized bone flap transplantation, arthroplasty, and arthrodesis, etc. Early avascular necrosis of the talus can be treated conservatively, and if treatment fails, core decompression can be considered. Arthrodesis is a remedial surgery for patients with end-stage arthritis and collapse, and in cases of severe bone loss, tibiotalocalcaneal arthrodesis and bone grafting are required. Vascularized bone flap transplantation is effective and plays a role in all stages of avascular necrosis of the talus, but the appropriate donor area for the flap still needs further to be studied.
UNASSIGNED: The surgical treatment and the system of treatment for different stages of avascular necrosis of the talus still need to be refined.
UNASSIGNED: 对距骨缺血性坏死手术治疗研究进展进行综述。.
UNASSIGNED: 广泛查阅近年来国内外距骨缺血性坏死相关文献,从发病机制、手术治疗方式及预后等方面进行总结。.
UNASSIGNED: 距骨缺血性坏死早期临床症状不明显,患者就诊时大多已进展至Ficat-ArletⅢ~Ⅳ期,需要手术治疗。目前,该病手术治疗方法主要包括髓芯减压、带血管蒂骨瓣移植、关节置换术及关节融合术等。早期距骨缺血性坏死可保守治疗,如治疗失败可以考虑髓芯减压。关节融合术应作为终末期骨关节炎和塌陷患者的补救手术,存在严重骨丢失时需行胫距跟融合术和植骨。带血管蒂骨瓣移植效果良好,对各期距骨缺血性坏死均有一定治疗效果,但合适骨瓣供区仍需进一步研究。.
UNASSIGNED: 距骨缺血性坏死手术方法以及不同分期治疗体系均有待完善。.
