Background:
Implant safety is a topic gaining more and more public interest. Implants are safety relevant medical devices which in the case of failure can lead to life-threatening situations.
Objectives:
A well-founded failure analysis requires expert knowledge not only of materials and implant design but also a qualified explantation procedure and storage conditions.
Methods:
A selective literature search was carried out putting the main emphasis on implant failure analysis supplemented with own investigations.
Results:
The reasons for implant breakdown are mostly failures of materials and in the manufacturing process. In some cases false material combinations can lead to tribocorrosion effects under cyclic loading.
Conclusion:
The increased level of knowledge gained from complex analyses of failed implants produces valuable evidence for better quality management.
