»: The blood supply to the talus is vulnerable to damage, making the talus susceptible to osteonecrosis, with limited treatment options.
»: Talar bone replacement has been investigated as a treatment option to preserve ankle function and maintain limb length.
»: Successful talar bone replacements have been performed for the past >35 years, with variations in design, methods of fixation, materials, and manufacturing techniques.
»: The designs of talar prostheses range from custom-made partial (talar body) or total prostheses to prefabricated universal (non-custom-made) prostheses.
»: Total talar prostheses have been demonstrated to function better than partial talar prostheses; however, there is a need for long-term studies regarding custom-made total talar prostheses and prefabricated universal talar prostheses in order to determine their long-term effectiveness.
»: 距骨的血供容易受损，这使得距骨易患骨坏死，且治疗选择有限。
»: 距骨置换已作为一种治疗选择进行了研究，以保留踝关节功能并维持肢体长度。
»: 在过去35年多的时间里已成功进行了距骨置换，在设计、固定方法、材料和制造技术方面存在差异。
»: 距骨假体的设计范围从定制的部分（距骨体）或全假体到预制的通用（非定制）假体。
»: 全距骨假体已被证明比部分距骨假体功能更好；然而，需要对定制全距骨假体和预制通用距骨假体进行长期研究，以确定它们的长期有效性。
