New insights into wear and biological effects of metal-on-metal bearings.
Tribology is a new topic for this blog. What is Tribology? Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Tribology is a branch of mechanical engineering. Interesting because it highlights the uncertainty that is caused by the metal wear debris and what the exact mechanisms are that cause the inflammation around the hip.
Another topic of discussion in this paper is theT lymphocyte-mediated hypersensitivity response from the wear rate. Cell-mediated immunity is directed primarily at microbes that survive in phagocytes and microbes that infect non-phagocytic cells. It is most effective in removing virus-infected cells, but also participates in defending against fungi, protozoans, cancers, and intracellular bacteria.
I continue to be interested in the potential in the metals in inhibiting the defences against cancer in the cells affected.
