Abstract:

BACKGROUND: Magnesium and magnesium alloys as new medical implant materials are a hotspot of biodegradable materials in recent years, including alloying, biocompatibility, surface modification coatings, which have a great progress.
OBJECTIVE: To summarize the present situation of domestic and international magnesium and magnesium alloy as medical implant materials.
METHODS: A computer retrieval of CNKI and PubMed database 1998-01/2010-10 for articles about magnesium and magnesium alloy was conducted. In the title and abstract, “metal matrix biological materials; medical implant materials; magnesium alloy; biodegradable; bone; biocompatibility” were used. Finally, 41 articles were reviewed in this article.
RESULTS AND CONCLUSION: Magnesium and magnesium alloys as new medical implant material with excellent mechanical properties and biodegradability are attracting more and more researchers' attention. But poor corrosion resistant performance of magnesium and magnesium alloy affects clinical applications. In order to improve the corrosion resistant performance, the researchers have performed magnesium and magnesium alloy surface treatment and made important progress. Magnesium and magnesium alloy are applied widely in biomedical metal implant material field.
