A model for radiation-induced changes in ultrahigh-molecular-weight polyethylene

Graphene nanoplatelet-induced strengthening of ultrahigh molecular weight polyethylene and biocompatibility in vitro.

Graphene nanoplatelets (GNPs) are added as reinforcement to ultrahigh molecular weight polyethylene (UHMWPE) with an intended application for orthopedic implants. Electrostatic spraying is established as a potential fabrication method for synthesizing large-scale UHMWPE-GNP composite films. At a low concentration of 0.1 wt % GNP, the composite film shows highest improvement in fracture toughnes...

Applications of Ultrahigh Molecular Weight Polyethylene Fibres in Dentistry: A Review Article

Introduction: Ultra High Molecular Weight Polyethylene Fibre (UHMWPE) is one of the most versatile materials that have been introduced in dentistry. It proves to be a boon to the clinicians on accord of its valuable and multifarious applications pertaining to every field of dentistry such as prosthodontics, restorative dentistry, endodontics, paedodontics, orthodontics as well as periodontics. ...

Notch fatigue of ultrahigh molecular weight polyethylene (UHMWPE) used in total joint replacements.

Ultrahigh molecular weight polyethylene (UHMWPE) has remained the primary polymer used in hip, knee and shoulder replacements for over 50 years. Recent case studies have demonstrated that catastrophic fatigue fracture of the polymer can severely limit device lifetime and are often associated with stress concentration (notches) integrated into the design. This study evaluates the influence of no...

Evaluation of the clinical performance of ultrahigh molecular weight polyethylene fiber cable using a dog osteosynthesis model.

The purpose of this study was to assess the removability and biological reactivity of an ultrahigh molecular weight polyethylene (UHMWPE) fiber cable as a new biomaterial for osteosynthesis. We used a pull-out test and an implantation test to analyze the performance of the UHMWPE fiber cable using a dog model, and compared its characteristics with those of a wire cable and a soft wire. In the p...
