The dream of biomedical device industries is to provide patients and clinicians with a new generation of implants that can perform its function then dissolve in the host body, eliminating the harmful effects of current permanent implants. Biodegradable metals, having the combination of strength, ductility and degradability, have been viewed as the ideal materials for making those dreamed implants. Published works on biodegradable metals have been significantly increasing from less than 50 papers in 2005 to more than 2,000 over 10 years. These metals have been attracting researchers in academia and industries alike as they can potentially revolutionize the medical products. The future trend goes toward adding bioactivities and exploring new clinical applications that require a temporary presence of load bearing implants. One of the latest development is the introduction of its porous structure for bone scaffolds. I am among the first to introduce porous biodegradable metal scaffolds with the works on new composites of porous iron-poly(lactic-
