Remelting of Highly Cross-linked Polyethylene Worn Under Laboratory Conditions

Clinical Value Dossier for Longevity Highly Cross-linked Polyethylene

PolyEthylene under Hybrid Propulsion Conditions

The inert and oxidative flash pyrolysis of High Density Poly-Ethylene (HDPE) is studied 6 up to 20 000 K.s, under pressure up to 3.0 MPa and at temperature ranging from 1000 K to 7 1500 K. These conditions are considered to represent those waited onboard a hybrid rocket 8 engine using HDPE as solid fuel. Recycling applications may also find some interest. The 9 pyrolysis products are quantified...

Cross-linked Polyethylene Engineered for TKA

Introduction It is well known that the wear resistance of ultra-high molecular weight polyethylene (UHMWPE) improves in proportion to the crosslinking irradiation dose. It is also well known that the mechanical properties and oxidative stability of UHMWPE are affected by the irradiation dose, resin type, and post-irradiation heat treatment, among others factors. Therefore, careful consideration...

In Vivo Wear Particles of Annealed Highly Cross-Linked Polyethylene in Total Hip Arthropalsty

INTRODUCTION: Polyethylene wear particles induce cytokine release by macrophage, which leads to osteolysis and aseptic loosening in total joint arthroplasties. Generation of polyethylene wear particles is one of the most important factors that affecting mid-term and long-term results of total hip arthroplasty (THA). Therefore, to reduce wear generation and to achieve better long-term results of...
