摘要: With the invention blocking systems for the medullary canal (1) of a tubular bone (2) are shown which have a blocking element (5) in order to hold bone cement (3) back from cemented prosthesis shafts (4). Because a deformable plug (6) which can be decomposed in the body is placed on between the blocking element (15) and the shaft end (7), which prevents an advance of liquid bone cement (3) in the capacity of a fill-in and which permits a penetration of the end (7) of the prosthesis shaft (4), a cement socket without a base arises which permits settling movements of the shaft in the hardened bone cement.

摘要: The acetabular prosthesis includes a metal supporting shell having collar-shaped projections which have tapered cutting edges for penetrating into the osseous tissue of a pelvic bone. The distal portions of the projections are tapered so that plugs of bone can be formed upon penetration of the projections into the osseous tissue. The projections may be filled with bone chips prior to fitting in of a plastic shell within the metal supporting shell. A multi layer metal mesh is provided on the outer surface of the metal shell for promoting fusion. If the overall attachment is not adequate, the projections can be used for insertion and centering of bone screws.
