Description
Die Erfindung bezieht sich auf eine Hüftgelenkprothese aus elastischem Material, insbesondere Kunststoff.The invention relates to a hip joint prosthesis made of elastic material, in particular plastic.
Die US-PS 27 65 787 zeigt eine starre Hüftgelenkprothese, bestehend aus einem in der Pfanne eines Beckenknochens verankerbaren, etwa kugeiförmigen Kopf und einem hierzu winkelig gerichteten und in einem Oberschenkelknochen verankerbaren langgestreckten Schaft. Dabei ist der Kopf mittels eines im Beckenknochen verankerten Halleteiles befestigbar, welcher von der der Pfanne gegenüberliegenden Seite des Beckenknochens her in eine den Beckenknochen durchsetzende, vorzufertigende Ausnehmung einführbar ist. Dieser Halteteil ist über eine Drahtlitze bzw. eine Kette, ein Verbindungsglied sowie eine Schraube mit dem Schaft der Prothese verbunden.The US-PS 27 65 787 shows a rigid hip joint prosthesis, consisting of one in the socket Pelvic bone anchored, approximately spherical head and an angled to this and in a thighbone anchored elongated shaft. The head is by means of an im Pelvic bone anchored hall part can be fastened, which from the side opposite the socket of the pelvic bone can be introduced into a prefabricated recess that penetrates the pelvic bone is. This holding part is with a wire strand or a chain, a connecting link and a screw connected to the stem of the prosthesis.
Die Hauptforderungen, welche man an Prothesen dieser Art zu stellen pflegt, sind die folgenden: Einfachheit im Aufbau und in der Montage, Gedrungenheit und damit geringster Raumbedarf, Verschleißfestigkeit und Robustheit. Diese Forderungen werden mit dieser bekannten Prothese aber auch nicht annähernd erfüllt. Diese bekannte Prothese ist im Aufbau und in der Montage äußerst kompliziert. Starkem Verschleiß ausgesetzte Drahtlitzen oder Ketten sind auch die denkbar ungünstigsten Elemente für diesen Zweck. Abgesehen davon liegen dort die Drahtlitzen bzw. Ketten auf dem Oberschenkelknochen teilweise auf und gelangen somit mit den diesen Knochen umgebenden Muskeln und dergleichen in unmittelbare Berührung. Bei Bewegung der Prothese treten dann zwischen diesen Muskeln einerseits und der Drahtlitze bzw. Kette andererseits Relativbewegungen auf, die aufgrund der damit verbundenen Reibungskräfte dem Prothesenbenutzer Schmerzen zufügen. Auch wird hierdurch die Betriebssicherheit der Prothese beeinträchtigt wenn nicht sogar infrage gestellt. Darüberhinaus macht diese Verbindungsart einen zusätzlichen Kanal im Oberschenkelknochen erforderlich, durch welchen die Drahtlitze bzw. Die Kette hindurchgeführt werden. Auf diese Weise wird der durch den Einsatz ohnehin schonThe main requirements that are usually placed on prostheses of this type are the following: Simplicity in construction and assembly, compactness and thus minimal space requirements, wear resistance and robustness. This known prosthesis does not even come close to meeting these requirements Fulfills. This known prosthesis is extremely complicated in structure and assembly. Heavy wear exposed wire strands or chains are also the most unfavorable elements imaginable for this purpose. Apart from that, the wire strands or chains on the thigh bone are partly on and on there thus come into direct contact with the muscles and the like surrounding these bones. When the prosthesis moves, these muscles occur on the one hand and the wire strand or chain on the other hand, relative movements, which are due to the associated frictional forces to the prosthesis user To inflict pain. The operational reliability of the prosthesis is also impaired as a result not even questioned. In addition, this type of connection creates an additional channel in the femur required, through which the wire strand or the chain are passed. on this will already be the case with the use
ίο geschwächte Oberschenkelknochen noch weiter geschwächt, was schwerwiegende Folgen haben kann, namentlich dann, wenn der Prothesenträger ziemlich alt ist und somit seine Knochen sehr spröde sindίο weakened thigh bones even further weakened, which can have serious consequences, especially if the person wearing the prosthesis is quite old and therefore its bones are very brittle
Aufgabe der Erfindung ist es, eine Hüftgelcnkendoprothese zu schaffen, die im Aufbau und in der Montage einfach, betriebssicher und auch gedrungen ist und darüberhinaus eine zusätzliche Schwächung des Oberschenkelknochens durch Kanäle zur Durchführung der Belestigungsmittel entbehrlich macht.The object of the invention is to create a hip joint endoprosthesis which, in terms of structure and assembly is simple, reliable and also compact and, moreover, an additional weakening of the thighbone makes dispensable through channels for the implementation of the Belestigungsmittel.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Halteteil mit einem im kugelförmigen Kopf angeordneten Verankerungsteil lösbar verbunden ist.According to the invention, this object is achieved in that the holding part has a spherical head arranged anchoring part is releasably connected.
Die Verbindung zwischen Oberschenkelknochen einerseits und Beckenknochen andererseits ist außerordenthch raumsparend, einfach und betriebssicher; sie ist darüberhinaus in diesen beiden Knochen voll integriert, so daß »auftragende Teile« nicht zu verzeichnen sind. Damit träten auch keinerlei Reibungskräfte zwischen den Muskeln einerseits und den BefestigungsmittelnThe connection between the femur, on the one hand, and the pelvic bone, on the other, is extraordinary space-saving, simple and reliable; it is also fully integrated in these two bones, so that "bulky parts" are not recorded. This means that there would be no frictional forces in between the muscles on the one hand and the fasteners
JO andererseits auf. Durch den Fortfall dieser Reibungskräfte verursacht diese Hüftgelenkendoprothese seinem Träger auch keinerlei Schmerzen und Unannehmlichkeiten. Auch wird eine Schwächung des Oberschenkelknochens im Bereich der Außenzone vermieden, da die Einarbeitung eines zusätzlichen Kanals zur Führung von Drahtlitzen, Ketten u. dg. in Fortfall gelangt. Alle diese Vorteile führen letzten Endes auch zu einer hohen Lebensdauer und einem den Prothesenträger psychisch nicht belastenden Einsatz. Wesentlich ist aber auch, daßJO on the other hand. By eliminating these frictional forces, this hip joint endoprosthesis causes his Wearers also have no pain or discomfort. There will also be a weakening of the thigh bone Avoided in the area of the outer zone, since the incorporation of an additional channel for guidance of wire strands, chains, etc. in discontinuation. All of these benefits ultimately lead to a high one Lifespan and a mission that does not put the prosthesis wearer under psychological stress. But it is also essential that
4» trotz aller dieser Vorteile der Halt zwischen dem Beckenknochen und dem Oberschenkelknochen nicht beeinträchtigt wird, so daß ein unDeabsichtigtes Lösen mit Sicherheit ausgeschlossen ist.4 »Despite all these advantages, the hold between the Pelvic bones and the thighbones are not affected, so that an unintentional loosening is definitely excluded.
