Endoprosthesis part for joint replacement, use of the endoprosthesis part and manufacturing process for endoprosthesis parts

摘要

The invention relates to an endoprosthesis part for use in joint replacement that comprises a body (6) and a multitude of force-absorbing areas (2), which are provided with the body (6) as one piece and which can absorb a force acting upon the endoprosthesis part, in particularly, when inserting the endoprosthesis into a bone. The inventive endoprosthesis part also comprises osseointegrative and/or osseoinductive or osseoconductive areas (4), which enable an osseous growing-in of the endoprosthesis part or stimulate or promote bone growth. The invention also relates to the use of the inventive endoprosthesis part as a cotyloid cavity, which is anchored without the use of cement and which is provided for accommodating a corresponding femoral head. The invention additionally relates to a production method for endoprosthesis parts involving the following steps: preparing a body (6) with force-absorbing areas (2) that are provided therewith as one piece; preparing areas (4) with osseointegrative and/or osseoinductive or osseoconductive properties, and; joining the body (6) to the osseointegrative and/or osseoinductive or osseoconductive areas (4).
