Stress fractures are common in people undergoing intense physical activity such as military recruits, manual laborers, and athletes. Graduate student Ryan Ross is working with Associate Professor Ryan K. Roeder as part of a team developing an X-ray contrast agent to more easily identify the microdamage in bone, which causes these fractures.
Ross has been designing methods to track nanoparticles in bone, selectively attaching those particles to damaged sites within bone, and then following the effects of the contrast agents (nanoparticles) in medical images. Funded by the U.S. Army, the development of such a non-destructive technique for detecting microdamage could translate into more accurate tests for assessing bone quality and fracture risk.
