Advances in the Study of Magnesium Alloys and Their Use in Bone Implant Material

Magnesium and magnesium alloys have great application potential in the field of orthopaedics. Compared with traditional inorganic nonmetallic materials medical polymer materials, many advantages, such as better strength, toughness, fatigue resistance, easy processing. Its mechanical properties are suitable controllable. It can meet same elastic modulus, cell compatibility, biodegradability human cortical bone. There also some drawbacks for biodegradability, its alloys, their high degradation rate, cause insufficient integrity properties. This paper summarises research on alloy bone implantation, looking at what are, history implant manufacturing bio-compatibility clinical applications shortcomings, progress recent years.
