WebMay 20, 2024 · Background The aim of the present retrospective study was to evaluate complications following carbon-fiber-reinforced polyetheretherketon (CFR-PEEK) volar plating in distal radius fracture in a large cohort of patients. As an alternative to conventional metallic devices, CFR-PEEK plates have been introduced over the last few years. Methods … Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. The polymer was first developed in November 1978, later being introduced to the market by Victrex PLC, then Imperial Chemical Industries (ICI) in the early 1980s. See more PEEK polymers are obtained by step-growth polymerization by the dialkylation of bisphenolate salts. Typical is the reaction of 4,4'-difluorobenzophenone with the disodium salt of hydroquinone, which is generated in situ by See more PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. … See more PEEK melts at a relatively high temperature (343 °C / 649.4 °F) compared to most other thermoplastics.
