The BMIS Coordinating Committee organized a workshop on September 19 and 20, 2002, in Gaithersburg, MD, to evaluate the role of the Federal Government in extracting and disseminating information gained from explanted medical implants to provide information

Wear Analysis of UHMWPE Using a Load Sum Method

October 12, 2021
Author(s)
M C. Shen, Stephen M. Hsu, John A. Tesk, A Christou
An accelerated wear test pro-cedure has been developed for wear screening of ultra-high molecular weight polyethylene (UHMWPE) using a new wear tester. Results showed that the test procedure was able to discriminate known wear level samples within seven
