Particle analysis for the determination of UHMWPE wear

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005
AbstractThree types of ultrahigh molecular weight polyethylene (UHMWPE) acetabular liners were tested against cobalt–chrome (CoCr) femoral heads on a hip simulator to approximately 20 million cycles. The materials included (1) conventional, nonirradiated liners (C‐PE); (2) 5 Mrad γ‐irradiated, remelted, and artificially aged liners (5‐XPE); and (3) 10 ...

Wettability of nano-epoxies to UHMWPE fibers

Journal of Colloid and Interface Science, 2006
Ultra high molecular weight polyethylene (UHMWPE) fibers have a unique combination of outstanding mechanical, physical, and chemical properties. However, as reinforcements for manufacturing high performance composite materials, UHMWPE fibers have poor wettability with most polymers.

Oxidation in Prosthetic UHMWPE

2019
In this chapter, we will consider the oxidation process involved in high-energy radiation sterilization of UHMWPE, as generally used in the field of orthopedics. The macroradicals produced during irradiation, their stability in various morphological phases, and their reactivity with chain imperfections, as well as the effect of oxygen and additives in ...

Interfacial strength between molded UHMWPE and PMMA-MMA monomer treated UHMWPE.

Journal of long-term effects of medical implants, 2000
To solve aseptic loosening of cemented acetabular cup and tibial plateaus of hips and knee joint prostheses in total joint replacement, adhesion between the polymeric prostheses made of ultra-high molecular weight polyethylene (UHMWPE) and bone cement made of polymethyl-methacrylate (PMMA) has been investigated. Previous studies using xylene, PMMA, and
