It’s versatility and precision allows for some amazing work to be done. Here is an example of a vertebral implant done in China. The idea is simple, but the execution was elegantly done. They used titanium that is already used safely for the main component of the vertebrae, and used a porous material that allows for fusion with the natural cell growth in the body. This brings up an interesting point about the development and implementation of new technology… In foreign countries we are seeing the rise of these 3-D printed implants being used in the clinics, but because of the strict restrictions in the U.S. most 3-D printing technology is still being used for imaging and modeling purposes. Of course this allows for increase in safety and ensures optimal integration of the technology, but creates too much barriers (incl financial, accessibility) for patients… I know we have readers pitching in from all over the world, what are your thoughts on regulations at your country? Do you feel like more regulations are needed, or maybe less?
