Conventional and Cross-Linked Polyethylene Properties
2005Highly cross-linked ultra high-molecular-weight polyethylene has shown great promise as an orthopedic bearing in total hip replacements. However, the enhanced resistance to plastic deformation that benefits wear behavior comes at the expense of other mechanical properties.

Unexpected Failure of Highly Cross-Linked Polyethylene Acetabular Liner
The Journal of Arthroplasty, 2012Highly cross-linked polyethylene (HXPE) in total hip arthroplasty has been shown to decrease wear rate compared with conventional liner. However, it has some disadvantages in that the mechanical properties cause early failure of the implant. This case report presents an unexpected failure of total hip arthroplasty in a 72-year-old woman that occurred ...

Comparison of Cross-Linked Polyethylene Materials for Orthopaedic Applications
Clinical Orthopaedics and Related Research, 2003Cross-linked polyethylenes are being marketed by orthopaedic manufacturers to address the problem of osteolysis caused by polyethylene particulate wear debris. Wear testing of these cross-linked polyethylenes in hip simulators has shown dramatic reduction in wear rate compared with standard ultrahigh molecular weight polyethylene, either gamma ...

Review on Recycling of Cross-Linked Polyethylene
Industrial & Engineering Chemistry ResearchCross-linked polyethylene is one of the most widely used thermosetting plastics. Due to its low cost, lightweight, and exceptional insulation properties against electricity and heat, it is frequently used as an insulation material for wires and cables.

Five-year Experience with Crossfire?? Highly Cross-linked Polyethylene
Clinical Orthopaedics and Related Research, 2005Our purpose was to compare the clinical wear performance of highly cross-linked (Crossfire) polyethylene with conventional (N2Vac) polyethylene total hip bearings. We implanted 56 hips (47 patients) with Crossfire acetabular bearing liners and compared their wear performance with 53 conventional polyethylene inserts.

SHORT-TERM IN VIVO WEAR OF CROSS-LINKED POLYETHYLENE
The Journal of Bone and Joint Surgery-American Volume, 2004Cross-linked polyethylene was developed to reduce volumetric wear in prosthetic joints. Hip simulator studies have shown promising results with regard to wear reduction. This study evaluated the short-term in vivo wear of a moderately cross-linked polyethylene.Linear head penetration, as an assessment of in vivo polyethylene wear, was measured in two ...

Electrochemical treeing at contaminants in polyethylene and cross-linked polyethylene insulation
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1973, 1973A hypothesis is presented which may be stated as follows: “In cables, the inception of electrochemical trees at the site of contaminants, is independent of the nature of the contaminants; it is a consequence of the presence of gaps or weak boundary layers at the contaminant-insulation interface, where liquid can collect; certain liquids, under the ...

Photoelastic Property of Cross-Linked Amorphous Polyethylene
The Journal of Chemical Physics, 1964By assuming the additivity of bond polarizabilities, a formal expression is derived for the difference Δγ in principal polarizabilities of a real polymer chain having constant end-to-end distance r. The expression is given as a series in powers of r2, whose coefficients are functions of the differences α1κ—α2κ in principal polarizabilities of ...

Cross-linked polyethylene: why the enthusiasm?
Instructional course lectures, 2001If these materials behave in vivo as they do in vitro and if no unexpected complications occur, periprosthetic osteolysis should be reduced, the duration of THR success should be greater, and the percentage of complications should be lower. Femoral loosening, socket loosening, and pelvic and femoral lysis should be reduced.
