摘要：

背景：因肿瘤型假体置换后并发症而再次手术的患者不断增加，其定制肿瘤假体的断裂是原因之一。
目的：总结分析定制肿瘤假体发生断裂的原因，以及其与假体设计的关系。
方法：以“定制肿瘤假体，假体断裂”为中文关键词；“Custom-made prosthesis, Endoprosthesis fatigue fracture”为英文关键词。采用计算机检索2000-01/2010-12相关文章。纳入与有关定制肿瘤假体设计及假体断裂翻修相关的文章；排除重复研究或Meta分析类文章。以14篇文献为主重点进行了讨论。
结果与结论：假体断裂的原因主要有假体设计缺陷，假体材料、加工工艺不合格，放置失误，手术软组织重建困难及缺少骨支撑等方面。通过了解肿瘤假体应力集中部位及应力峰值，可以预测内固定系统的寿命。

Abstract:

BACKGROUND: The number of patients receiving second operation due to complications after tumor prosthesis replacement is increasing, and custom-made prosthesis fracture is one of the reasons. 
OBJECTIVE: To analyze the reasons for custom-made prosthesis fracture, and to investigate their relationship with prosthesis design.
METHODS: A computer retrieve was performed for related articles published from January 2000 to December 2010 using keywords of “custom-made prosthesis, endoprosthesis fatigue fracture” in Chinese and English. Articles about custom-made prosthesis fracture and design were included. Repetitive articles or Meta analysis were excluded. Totally 14 articles were included in result analysis.
RESULTS AND CONCLUSION: The main reasons for prosthesis fracture included design defects, material and process failure, place errors, difficulty in soft tissue reconstruction, and lack of bone support, and so on. The life of fixation system could be predicted based on prosthesis stress site and peak.
