摘要: A bone implant is provided with undercut anchoring areas for bone tissue which extend from the surface of the implant into the interior. Geometrically shaped cavities are generated through the openings in an interconnected manner to provide for the ingrowth of bone tissue. A high pressure liquid jet is used to form the cone-shaped cavities in the implant on spacings to provide for intercommunication between the respective cavities.
