1) Die Erfindung betrifft einen Acetabulumko-'b mit welchem das gesamte Acetabulum stabilisiert werden soll.1) The invention relates to an acetabulumko-'b with which the entire acetabulum is to be stabilized.

2) Der Acetabulumkorb besteht aus einer gelochten Ganzschale, versehen mit drei oder mehreren Abstützlaschen, oder durchgehendem um 900 abgewinkeltem Rand, der für Stabilisierung für Pfannengrund- oder Randdefekte, sowie für durchbohrte Pfannenlager gedacht ist.2) The acetabular basket consists of a perforated whole shell, provided with three or more support straps, or continuous at 900 angled Edge, which is intended for stabilization for socket base or rim defects, as well as for pierced socket bearings is.

3) Der Erfindung liegt die Atfgabe zugrunde, bei erheblicher Perforation des Acetabulums oder Randdefekten deselben, wie sie unter anderem auch besonders bei rrothesenwechseln auftreten können, eine sichere Pfannenverankerung für Totalprothese zu gewährleisten, ferner die auftretenden statischen und dynamischen Drücke aufzunehmen. 3) The invention is based on the Atfgabe, with considerable Perforation of the acetabulum or marginal defects of the same, as they are, among other things, especially in prosthesis changes can occur, a secure socket anchoring to ensure for full dentures, also to absorb the static and dynamic pressures that occur.

4·) Es ist L'wkannt, daß die zur Verfügung stehenden, halbschaligen verformbaren Kreuznetze sich nur zum Beheben kleiner im Acetabulum-Zentrum befindlichen Pfannendefekte eignen. Eine Stabilisierung konnte mit den herkömmlichen Netzen nicht erreicht werden. Ein Durchbrechen des Pfannendaches oder -bodens bei auftretenden starken Drücken war nicht mit Sicherheit zu verhindern. ,4 ·) It is known that the available, half-shell Deformable cross meshes are only used to repair small acetabular defects in the center of the acetabulum suitable. Stabilization could not be achieved with the conventional networks. Breaking through the roof of the pan or -bottom with occurring strong pressures could not be prevented with certainty. ,

5) Die Aufgabe wird erfindungsgemäß dadurch gelöst: Der Acetabulumkorb besteht aas einer Ganzschale mit runder oder eckiger Perforation, netzartig angeordnet und ist aus gewebeverträglichem Material hergestellt* Zur Abstützung des Pfannenrandes besitzt die Ganzschale einen5) The object is achieved according to the invention as follows: The acetabular basket consists of a whole shell with a round one or angular perforation, arranged like a net and made of tissue-compatible material * For support The whole bowl has one of the edge of the pan

um 90° abgewinkelten, rundumlaufenden Rand, oder für denselben Zwack drei oder mehrere Abstützlaschen-90 ° angled, all-round edge, or for the same Zwack three or more support tabs

6) Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß bei schweren Pfannengrund- oder Randdefekten sowie in mehrmfach durchbohrten Pfannenlagern, wie dies unter anderem häufig bei Prothesenwechseln vorgefunden wird, durch die Einlage des Acetabulumkorbes, eine sichere und bruchfeste Lagerung der Kunststoffpfanne ermöglicht wird. Ferner vexxhindert der Acetabuluiakorb, daß der Zement in der knetbaren Phase suweit in das Becken eingedrückt werden kann. Die Verteilung der Belastungsdrücke ist durch die erreichte Armierung wesentlich gleichmäßiger und sicherere6) The advantages achieved with the invention are, in particular, that in the case of severe defects in the base of the cup or the edge of the cup and in cup bearings with multiple holes, as is often found when replacing prostheses, the insert of the acetabular basket enables a secure and break-proof storage of the plastic cup . Furthermore vex x prevents the Acetabuluiakorb that the cement can be pressed into the kneadable suweit phase in the basin. The distribution of the load pressures is much more even and safer due to the reinforcement achieved
