Abstract
A hip joint prosthesis in the form of a femur head prosthesis or acetabulum has a mesh secured over at least part of the implant surface to define a cavity between the mesh and the supporting member of the prosthesis. The mesh is made of elastically deformable material to permit inward deformation during implantation. In addition, bone cement can be injected into the cavities so that the mesh then follows the individual shape of the cavity in the bone to mesh into the internal structure of the bone with hardened bone cement.
