Processing and rheological behavior of cross‐linked polyethylene containing disulfide bonds

SPE Polymers, 2022
Vitrimers are a new class of materials that consist of chemically cross‐linked networks that engage in thermoactivated associative exchange reactions. These exchange reactions can impart malleability, healing, and recyclability properties to thermosets ...

Is there evidence for accelerated polyethylene wear in uncemented compared to cemented acetabular components? A systematic review of the literature [PDF]

, 2013
Joint arthroplasty registries show an increased rate of aseptic loosening in uncemented acetabular components as compared to cemented acetabular components.

Massive Osteolysis in a Modern Total Knee Prosthesis

Case Reports in Orthopedics, 2021
Case. An 82-year-old woman underwent right total knee replacement with a sequentially irradiated and annealed highly cross-linked polyethylene insert. At 9 years, she was found to have a massive femoral osteolysis with an impending fracture.

Kinetic modelling of phenols consumption during polyethylene thermal oxidation [PDF]

, 2013
Irganox 1010 stabilized PE was monitored by carbonyl build-up and DSC under oxygen. A scheme for PE stabilization by phenols was implemented and its kinetic parameters were calculated from experimental results.

Early failure of sequentially annealed polyethylene in total knee arthroplasty

Arthroplasty Today, 2020
Improvements in the processing of polyethylene have led to a dramatic reduction in wear rates in total hip arthroplasty. This led to the adoption of modern highly cross-linked polyethylene in total knee arthroplasty (TKA).

Wear, bone density, functional outcome and survival in vitamin E-incorporated polyethylene cups in reversed hybrid total hip arthroplasty: design of a randomized controlled trial

BMC Musculoskeletal Disorders, 2012
Background Aseptic loosening of total hip arthroplasties is generally caused by periprosthetic bone resorption due to tissue reactions on polyethylene wear particles.

Correlations between physico-chemical properties and dielectric behavior of thermally aged XLPE cables insulation

ENP Engineering Science Journal, 2022
The carried out investigations aim at clarifying the correlations between physico-chemical properties and the variation of dielectric losses of Cross-Linked Polyethylene (XLPE) as Medium Voltage cable insulation during thermal aging. The used cables were

Mobility‐limited charge injection in cross‐linked polyethylene under extra high electric field

High Voltage, 2021
In this study, characteristics of charge injection under extra high electric field (above 100 kV/mm) in cross‐linked polyethylene (XLPE) were investigated by experiments of conduction current and space charge.

Incarcerated fracture fragments of Longevity polyethylene liners after total hip arthroplasty

Arthroplasty Today, 2016
Highly cross-linked polyethylene liners are widely used in total hip arthroplasty because they experience lower wear rates than conventional polyethylene liners.

High survivorship of highly cross-linked polyethylene in revision Total hip Arthroplasty: a minimum 10-year follow-up study

Arthroplasty, 2019
Purpose Highly cross-linked polyethylene has been introduced to decrease osteolysis secondary to polyethylene wear debris generation. However, few long-term data on revision total hip arthroplasty (THA) using highly cross-linked polyethylene liners are ...
