A Spanish hospital recently replaced a significant amount of a man’s rib cage and sternum with a titanium replacement. Putting titanium inside people’s chests is nothing new, but what made this different was the implant was 3D printed to match his existing bone structure.
An Australian company, Anatomics, created the 3D print from high-resolution CT scans of the patient. They used a printer provided by an Australian Government corporate entity, CSIRO, that helps bring technology to Australian companies.
Biomedical printing has been in the news quite a bit lately and we’ve covered CT scan to 3D model conversions more than once. Is this the dawn of the age of the cyborg? Maybe it’s really mid morning. Many people walk around with pacemakers, Vagus nerve stimulators, and plenty of more conventional titanium hardware in them now.
While the ethics of replacing a cancer patient’s rib cage is pretty clear, the real issue will be when people want enhancements just for the sake of it (think of the controversy surrounding runners with prosthetic legs, for example). It might seem far-fetched, but as replacements become better than originals, some people will want to opt for replacements for perfectly good body parts.
