Abstract: An assembly for fixating a prosthesis in body tissue such as bone of a mammal, comprising a mechanical compacting device and a mass comprising at least granules of a biocompatible material having a sponge-like structure, wherein the mechanical compacting device is designed for compacting the granules during use by insertion of the device in a hole in bone and subsequently inducing relative movement of at least a first part of the compacting device relative to a second part thereof, such that the volume of at least one space between at least part of an outer surface of the device and the adjacent inner surface of said hole is reduced.

Abstract: Kit of parts, comprising: a prosthesis or prosthesis part having at least one contact surface; metal granules having an internal porosity; bone cement; and further comprising titanium granules for use in a kit of parts, which granules preferably are osteoconductive, which granules preferably are coated with a coating from the group of osteoconductive or osteoinductive coatings, or coatings comprising bioceramic, bioglass or osteoconductive or osteoinductive molecules or fluids or cells.

Abstract: Embodiments are directed to moulded article, provided with granules made of a bio-compatible material, which granules have a substantially porous structure and are interconnected, forming a rigid or semi-rigid structure; a mass for forming such a moulded article; and a method for forming a moulded article, comprising the steps of providing a mass comprising at least granules made of a bio-compatible material and having a porous structure, and pressing said mass, especially said granules together, for forming a rigid or semi-rigid structure.

Abstract: The invention relates to a supporting element for attachment to bone, including means for placement of attachment means, such as screws or tape, and a surface for positioning against the bone, wherein the surface is, at least during use, provided with sponge-like biocompatible material enclosed between the bone and the surface.
