In early 2016, the BBC Horizons aired a reportage about a special metal bone screw implanted in the broken
finger bone of a male Korean patient 1 The patient returned to the hospital four months after the surgery with a smiling
face because his broken bone had been healed and he did not need to go for a second surgery as the screw has gone away.
This media highlight is an example demonstrating that the biomedical device industries are constantly making innovation
to provide patients and clinicians with advanced products. In this case, a new generation of metal implants that dissolve
in the body after providing the needed function, eliminating the harmful potential effects of permanent metal implants.
After decades of acknowledging that metal implants must be corrosion resistant, nowadays corrodible metals are
considered for medical applications. The interest toward these corrodible or absorbable metals has been marked by the
rapid increase of related scientific publications and the recent development of new standards on its materials, process,
and testing procedures by the ASTM subcommittee F04.15 2-3. Today, at least two medical companies have launched their
commercial absorbable metal products.
