Abstract

A body (2) for distributing bone cement (8) rests by an elastic collar (4) against the outer edge of a hollow (1) in the bone and has a passage (5) through into the hollow (1) in the bone, into which a syringe (6) for bone cement may be inserted. In the hollow (1) in the bone the body (2) is made as a displacement body of the shape (3) of the implant which is to be inserted later. During injection into the space between the body and the hollow in the bone a designed pressure is maintained until the viscosity of the bone cement (8) is adequate for taking the body (2) out of the hollow (1) in the bone without bone cement (8) flowing back. Subsequently the actual implant may be pressed into the thus prepared but still plastically deformable countermould of bone cement (8) .
