Orthopedic implants first started out as an all-metal hip joint replacement. However, poor design and machinability as well as unsatisfactory surface finish subjected the all-metal joint replacement to being superseded by a polyethylene bearing. Continued improvement in manufacturing techniques together with the reality that polyethylene wear debris can cause hazardous reactions in the human bo...

INTRODUCTION: Magnesium (Mg) alloys are promising biodegradable metallic materials for orthopedic implants due to their many desirable properties. Mg has a mechanical strength and elastic modulus similar to cortical bone [1], and the degradation products can be naturally metabolized [2]. Furthermore, increased bone growth has been observed surrounding Mg derived implants in vivo [3]. However, r...
