Abstract:

BACKGROUND: Magnesium alloys have good application prospect in the biomedical implant material, especially, in the degradable hard issue implant material areas with prominent superiorities, such as good biocompatibility and biodegradability. However, their high corrosion rate is the key disadvantage desiderated to be improved before their application in clinic.
OBJECTIVE: To summarize the advantages and disadvantages of magnesium alloys as medical implant materials and to conclude the latest progress of magnesium alloys as biomedical implant materials.
METHODS: ScienceDirect and CNKI databases were searched by using the keywords of “magnesium; magnesium calcium alloy; biodegradable; biomaterials” in English and Chinese for relevant articles about magnesium alloys as biomedical implant materials. Finally, 34 articles were included.
RESULTS AND CONCLUSION: Magnesium calcium and its alloys are one of the development directions of biomedical implant materials; and the rapid solidification technique is a promising method to improve the corrosion property of magnesium alloys; it can get insight into the microscopic mechanisms of magnesium alloys as implant materials with computer simulation methods; in addition, the theory study of magnesium alloys needs to translate to clinical study and impel its clinical application as soon as possible.
