The Use of Carbon-Fiber-Reinforced (CFR) PEEK Material in Orthopedic Implants: A Systematic Review
Carbon-fiber-reinforced polyetheretherketone (CFR-PEEK) has been successfully used in orthopedic implants. The aim of this systematic review is to investigate the properties, technical data, and safety of CFR-PEEK biomaterial and to evaluate its potential for new innovation in the design of articulating medical devices. A comprehensive search in PubMed and EMBASE was conducted to identify artic...
متن کاملIn vivo implant fixation of carbon fiber-reinforced PEEK hip prostheses in an ovine model.
Carbon fiber-reinforced polyetheretherketone (CFR/PEEK) is theoretically suitable as a material for use in hip prostheses, offering excellent biocompatibility, mechanical properties, and the absence of metal ions. To evaluate in vivo fixation methods of CFR/PEEK hip prostheses in bone, we examined radiographic and histological results for cementless or cemented CFR/PEEK hip prostheses in an ovi...
متن کاملPerturbation effects of the carbon fiber‐PEEK screws on radiotherapy dose distribution
Radiation therapy, in conjunction with surgical implant fixation, is a common combined treatment in cases of bone metastases. However, metal implants generally used in orthopedic implants perturb radiation dose distributions. Carbon-Fiber Reinforced Polyetheretherketone (CFR-PEEK) material has been recently introduced for production of intramedullary nails and plates. The purpose of this work w...
متن کامل• Self-initiated surface graft polymerization of poly(2-methacryloyloxyethyl phosphorylcholine) on PEEK and carbon fiber reinforced PEEK for orthopaedic and spinal applications
INTRODUCTION: Poly(ether-ether-ketone) (PEEK) is considered to be promising novel polymer biomaterial for orthopaedic and spinal applications, because PEEK exhibits excellent mechanical properties, chemical stability, non-magnetic nature, and compatible with reinforcing agents such as carbon fibers, as compared with polyethylene or metallic materials. However, since conventional PEEK cannot sat...
متن کاملEarly Peek Advantage?
From 2007 to June 2013, a small group of fee-paying, high-speed traders receive the Michigan Index of Consumer Sentiment two seconds before its broader release. Within this early peek window, we find highly concentrated trading and a fast price discovery of less than 200 milliseconds. Outside this narrow window, general investors trade at fully adjusted prices. We further establish a casual rel...
