From the patent document US 5,702,447 A a glenoid prosthesis is known having a metal base flat executed for screwing in a shoulder blade bone. The metal base is provided on its inside with a rib. A trough-shaped plastic socket part can be guided in and inclined position partially under the rib are finally tallsockel firmly connected by descent printing with the metal. The exact positioning of the plastic socket part in the metal base requires a high precision. A substance located between the plastic socket part and the metal base, such as blood or tissue parts can prevent an occurrence of the connection. With a simple tilt the plastic socket part can be released from the metal base and the prosthesis is no longer functional. The two components of the prosthesis, plastic socket part and the metal base are then completely detached from each other and can not be fixed to each other by a simple procedure again.
From patent application US 2004/0064189 Al a glenoid component is known with an anchoring member which is anchored by a screw in a bone, and a socket part, which is connected via a latching means located at the bottom thereof with the anchoring part.

Preferably, the width of the thickened portion 12 is about 5 percent of the inner diameter of the guide 8 excluding the thickening 12 and the width of the opening 11 is about 5 percent of the outer diameter of the pin 5 without consideration of the aperture 11. The connection means 4 preferably has a diameter of 3 amounts to 9 millimeters, especially 6 to 7 millimeters.
The values ​​given in relation to that shown in Figures 1 and 2, dimensions allow a fixed connection between the socket part 2 and the anchoring part 3 by the application of low insertion force, while at the same time be adhered to dissolve the solid compound the required press-out forces. Figure 3 shows a sectional view of a
Prosthesis 1, as shown in Figure 1, are provided in addition hindurch- through the outlet openings 9 cross-fixing means 25, in particular screws, for fastening the anchoring part 3 in a bone. The axes 26, 27 of the fastening means preferably do not extend parallel to the axes 28 of the pins 5. In this way, an improved anchoring can be achieved. The inclination of the axes 26, 27 of the fastening means 25 over the axes 28 of the pins 5 is preferably from 4.5 to 6 degrees. A particularly good grip in the bone can be obtained when the inclination of the axes 26, 27 of the fastening means 25 over the axes 28 of the pins 5 is different in size. Thus, the inclination of the axis 26 of a first fastener 25 with respect to the axis 28 of a first pin may for example be 4.5 degrees 5 5 6 degrees and the inclination of the axis 27 of a second fastening means 25 with respect to the axis 28 of a second pin.
For implantation, or for implantation of the prosthesis 1 into a bone in a first step, the guides are inserted into the bone. 8 This can be done for example by screwing the screws 25 and / or by applying a force, for example by means of a hammer. In a further step, the socket part 2 is connected to the anchoring member 3 in that the pins are inserted in the guides 8. 5 The pins 5 are inserted into the guides 8 until by the connecting means 4 is a rigid connection between the socket member 2 and the pins 5 and the anchor portion 3 and the guides has been formed. 8 The pins 5 are guided over during insertion into the guides 8 via the respective bulges 12 of the connection means. 4 In this case, snap or catch the thickened portions 12 in the openings 11 and thus create a solid, that is not easily releasable, connection between the pins 5 and the guides 8, and thus 3 between the socket part 2 and the anchoring part can, of course, such a assembly of socket part 2 and approximately anchoring part 3 carried out even outside a human or animal body.
The thickener 12, which is engaged in the opening 11 and snapped, prevents the pins 5 can simply slide out of the guides 8 again. If, nevertheless, for example by a rocking motion, the thickening separated from the aperture 11 12, the pins remain 5 advantageously in the guides 8 and are held by this, that is, connects fertil of socket part 2 and the anchoring part 3 is not completely dissolved and remains repairable. A renewed solid connection can easily be achieved by the socket part 2 and thus the pins 5 are pushed so far in the direction of the output ports 9 that the thickening effects 12 again snap into the openings. 11
