Recently, the interest in biomedical magnesium alloys has been increased. In this paper, to understand biomedical magnesium alloys research and development trends, we investigated total 590 research papers published from 2001 to 2012. These papers were published by 437 institutes of 39 countries. The biomedical magnesium alloys study had significantly increased since the late 2000’s. Hannover Med. Sch.(4.4) and Monash Univ.(3.2) had the highest Q1 (index level of paper quality) and Q2 (strength of international collaboration) value, respectively. Main research topics were biodegradation, biocompatibility, biomaterials, biodegradable materials, biodegradable stents, bioactivity, bio-corrosion and in vitro.
