Wear of ceramic-on-carbon fibre reinforced PEEK hip replacements
ثبت نشده
چکیده
Total hip replacement has been a successful surgical intervention for many years. However, concerns regarding UHMWPE wear particle induced osteolysis [1], have led to alternative bearing materials to be sought. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) is a fibre-reinforced polymer which has shown reduced wear in hip and knee configurations compared with conventional polyethylene [2-4]. The aim of this study was to investigate the wear performance of a ceramic-on-CFR PEEK total hip replacement bearing through in-vitro wear simulation.

Wear and Wear Debris Generated from Ceramic-on-Carbon Fibre Reinforced PEEK Hip Replacements
INTRODUCTION Concerns regarding UHMWPE wear particle induced osteolysis [1] have led to investigations of alternative bearing materials. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) has been shown in animal studies to have a similar biological activity to UHMWPE [2], whilst hip and knee configurations incorporating this polymer display reduced wear rates when compared with convent...
متن کاملThe wear properties of CFR-PEEK-OPTIMA articulating against ceramic assessed on a multidirectional pin-on-plate machine.
In an attempt to prolong the lives of rubbing implantable devices, several 'new' materials have been examined to determine their suitability as joint couplings. Tests were performed on a multidirectional pin-on-plate machine to determine the wear of both pitch and PAN (polyacrylonitrile)-based carbon fibre reinforced-polyetheretherketone (CFR-PEEK-OPTIMA) pins articulating against both BioLox D...
متن کاملAre PEEK-on-Ceramic Bearings an Option for Total Disc Arthroplasty? An In Vitro Tribology Study
BACKGROUND Most contemporary total disc replacements (TDRs) use conventional orthopaedic bearing couples such as ultrahigh-molecular-weight polyethylene (polyethylene) and cobalt-chromium (CoCr). Cervical total disc replacements incorporating polyetheretherketone (PEEK) bearings (specifically PEEK-on-PEEK bearings) have been previously investigated, but little is known about PEEK-on-ceramic bea...
متن کاملPEEK and CFR-PEEK as alternative bearing materials to UHMWPE in a fixed bearing total knee replacement: An experimental wear study
New bearing materials for total joint replacement have been explored as the need to improve longevity and enhance performance is driven by the changing demands of the patient demographic. Carbon-reinforced PEEK has demonstrated good wear characteristics in experimental wear simulation in both simple geometry pin-on-plate studies and in total hip joint replacement. Carbon reinforced PEEK CFR-PEE...
متن کاملTechnical and histologic analysis of a retrieved carbon fiber-reinforced poly-ether-ether-ketone composite alumina-bearing liner 28 months after implantation.
A new innovative low-wear bearing for use in total hip arthroplasty, a wear couple consisting of carbon fiber-reinforced poly-ether-ether-ketone (CF-PEEK), has been shown to be highly biocompatible and to have excellent tribological performance in the laboratory. We report the results of our technical and histologic analysis of a CF-PEEK composite acetabular cup component articulating against a...
