ABSTRACT:
An improved method of producing a site for tissue ingrowth on a surgical implant by embedding a space occupier possessing a desired pattern in the surface of the implant at the desired location for ingrowth and then solubilizing the embedded space occupier to leave the pattern on the implant surface. Preferably, the implant is fabricated from a composite comprising a semi-crystalline thermoplastic resin such as polyetheretherketone or polyphenylene sulfide, and the space occupier is an acid-soluble metal plate machined to produce the desired pattern and removed by aqueous acid solution. The space occupier is embedded onto the composite surface by induction heating.
