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.
