Radiation boost for artificial jointsLondon, UK (SPX) Sep 23, 2011 A blast of gamma radiation could toughen up plastic prosthetic joints to make them strong enough to last for years, according to researchers in China writing in the current issue of the International Journal of Biomedical Engineering and Technology. Whole joint replacement, such as hip and knee replacement, commonly use stainless steel, titanium alloys or ceramics to replace the damaged or diseased bone of the joint. Non-stick polymer or nylon is usually used to coat the artificial joint to simula ... read more |
