Orthopedic surgery needs a strong bioabsorbable bone and ligament fixation material to obviate the pain, cost and infection-risk of secondary removal operations. Such operations are often required for non-bioabsorbable implants. Also, current polymer bioabsorbables are not strong enough for many fixation procedures. Thus arises the opportunity for strong, bioabsorbable and biocompatible Mg alloys. BioMg ® 250 was developed to fill this need. The alloy design theory and practice are described, as are the mechanical properties, corrosion resistance in vitro in Synthetic Body Fluid. BioMg 250 properties are correlated with fine grain size and nanometer- sized microstructures. Then in vivo animal studies and biotoxicity evaluations will be reviewed; demonstrating good biocompatibility and that BioMg 250 promotes new bone growth.
