摘要: Composites, constructs and implants comprising a non-resorbable polymer, such as polyetheretherketone (PEEK), having structure of interconnected struts, which may be coralline. Composites may comprise a first phase comprising a ceramic; and a second phase comprising a non-resorbable polymer; wherein each of the first and second phases have an interconnected strut structure and are substantially continuous through the composite. Implants may also comprise a non-porous component containing the non-resorbable polymer that is contiguous with a surface of the core, a surface of the porous layer (if present), or both. Methods are also provided comprising infusing a porous ceramic body, having a plurality of interconnected channels, with a non-resorbable polymer.
