Not all broken bones heal. But one scientist at the University of Arizona hopes to remedy that problem using a combination of 3D printing 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 A. Szivek, PhD, a scientist at the UA College of Medicine – Tucson. “This is a really big problem for the military, where explosions or combat injuries can cause big bone defects.”
To help military personnel with these devastating injuries, Dr. Szivek, a biomedical engineer and professor of orthopedic surgery, has received a five-year, $2 million grant from the U.S. Department of Defense to launch a study to determine how to heal bone fractures using a combination of 3D printing and adult stem cells.
