SummaryA new prosthetic material, ultra-high molecular weight (UHMW) polyethylene graphite, was developed for use in total joint replacement and found to exhibit 1/7-1/30 lower wear rate than UHMW polyethylene bearing against Vitallium alloy.A preliminary study was undertaken to test the biocompatibility of the new material. Specimens of 316L stainless steel, high-purity graphite, UHMW polyethylene, and the composite material were implanted in rabbits and cynomologous monkeys. The materials were evaluated in …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
