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...
متن کاملGraphene Oxide/Ultrahigh Molecular Weight Polyethylene Composites: Ball-Milling Preparation Mechanical Performance and Biocompatibility Effects
Graphene oxide (GO)/ultrahigh-molecular-weight polyethylene (UHMWPE) composites were successfully fabricated through the mechanical ball milling technology and processed according to the hot pressing method. The fractured microstructure features and mechanical properties of the GO/UHMWPE composites were investigated by Scanning electron microscope (SEM) and universal testing machine, respective...
متن کاملTotal hip replacement using a highly crosslinked polyethylene liner in Asians with small acetabulum.
PURPOSE To evaluate the medium-term outcomes of total hip replacement (THR) using a thin highly cross-linked polyethylene (HXLPE) liner in an Asian population. METHODS Medical records of 20 men and 44 women aged 26 to 80 (mean, 59) years who underwent 80 THRs using a thin HXLPE liner by a single surgeon were reviewed. Indications for THR included dysplasia (n = 26), avascular necrosis (n=26),...
متن کاملSurfactant Effects on Structure and Mechanical Properties of Ultrahigh-Molecular-Weight Polyethylene/Layered Silicate Composites.
In this study, the reinforcement of ultrahigh-molecular-weight polyethylene (UHMWPE) with biotite was investigated. The biotite filler was mechanically activated with different dry surfactants to improve its compatibility with UHMWPE and decrease agglomeration among biotite particles. Alkyldimethylbenzylammonium chloride (ADBAC) and cetyltrimethylammonium bromide (CTAB) were selected as cationi...
متن کاملPolyethylene Oxidation in Total Hip Arthroplasty: Evolution and New Advances
Ultra-high molecular weight polyethylene (UHMWPE) remains the gold standard acetabular bearing material for hip arthroplasty. Its successful performance has shown consistent results and survivorship in total hip replacement (THR) above 85% after 15 years, with different patients, surgeons, or designs. As THR results have been challenged by wear, oxidation, and liner fracture, relevant research ...
