Joint solution

Gamma radiation can improve the biocompatibility and wear resistance of artificial, or prosthetic, joints according to researchers in China. Maoquan Xue of the Changzhou Institute of Light Industry Technology, has investigated the effect of adding ceramic particles and fibers to two experimental materials for coating prosthetic joints, UHMWPE (ultra-high-molecular-weight polyethylene) and PEEK (polyether ether ketone). He has demonstrated that radiation treatment of these composites leads to much more robust materials for prosthetic joints.
