Cementless surface replacement prosthesis for the natural femoral head

摘要

The present invention relates to a ceramic surface replacement prosthesis for a natural femoral head (3) comprising an outer spherical surface (5) and an inner receiving chamber (7) having an inner peripheral surface (4). Regarding 1). In order to prevent bone tissue necrosis during implantation and to prevent loss of inner bone tissue, according to the present invention, the inner peripheral surface (4) Is provided with an osseointegrative covering (6) at least in a predetermined range, or is formed osseointegratively, and / or the inner peripheral surface (4) is self-molding. It is proposed to be formed as a thread (8).
