3D printed scaffolds for regenerative bone healing strategy

Researchers at the University of Arizona College of Medicine - Tuscan (AZ, USA) are working to improve bone healing for army veterans by 3D printing bone scaffolds incorporating calcium particles and adult stem cells. "Imagine an impact that causes half of a long bone to shatter so that it can't be put back together – no current surgical treatment can ensure that kind of injury will heal," explained John Szivek (University of Arizona College of Medicine – Tucson; AZ, USA). "This is a really big problem for the military, where explosions or combat injuries can cause big bone defects." In...
