...of the effects of cross-linking on polyethylene morphology and mechanical properties,20,21 these are the first studies that demonstrate the advantage of cross-linking UHMWPE for use in total-hip-replacement prostheses. Laboratory hip-simulator wear tests have shown that there is a decrease in UHMWPE wear rate...

...and adhesion. A recently introduced device that optimizes the wear testing of hip implants is described in the sidebar below. PIB-Based Material May Offer Alternative to Silicone Rubber. Sidebar: Dual-Station Simulator Takes Wear. and Tear Out of Hip Implant Testing. A material containing polyisobutylene (PIB...

...of this potential is an orthopedics company 's development of a carbon fiber -reinforced PEEK (CF-PEEK) polymer composite acetabular liner, which is used for articulation against a ceramic femoral head. Hip-joint simulator testing up to 10 million cycles showed that wear of the CF-PEEK polymer composite...

...of a hip stem implant. Figure 1. Example of an FE model of a resurfaced hip generated from QCT data. Given the multifactorial nature of implant performance, FEA is particularly useful in ranking different designs. For example, design A can be compared with design B under identical conditions...

...a ceramic femoral head. Hip-joint simulator testing up to 10 million cycles showed that the wear of the CF-reinforced PEEK polymer composite cups was approximately 1% that of ultra-high molecular weight polyethylene (UHMWPE) cups.1 Further work using CF-reinforced PEEK acetabular cups wearing...
