Abstract
Description
Die Erfindung bezieht sich auf eine Hüftgelenkendoprothese mit einem im Oberschenkelknochen zu verankernden Schaft und einer lateralen Zuggurtung, die ein den Prothesenschaft nahe dessen proximalen Ende mit einem lateralen Teil des Oberschenkelknochens verbindendes Zugglied umfaßt.The invention relates to a hip joint endoprosthesis with a shaft to be anchored in the thigh bone and a lateral drawstring that fits the prosthetic socket near its proximal end with a lateral part of the Thigh connecting connecting member includes.
Es ist bekannt (DE-OS 28 32 555), daß man im Bereich des proximalen Schaftendes eine Überlastung der medialen und eine Entlastung der lateralen Knochenbereiche, die beide für eine Rückbildung des Knochengewebes und damit für eine Prothesenlockerung verantwortlich sein können, dadurch ver meiden oder vermindern kann, daß man Kräfte vom proximalen Schaftende mittels einer sogenannten Zuggurtung auf die lateralen und weiter distal gelegenen Teile des Knochens ableitet. Als Zuggurtung kann beispielsweise eine Schraube verwendet werden, die von der den Schaft proximal ab schließenden Auflageplatte zu einer distal des großen Trochanter angeordneten Platte führt, die dort die Zug kraft der Schraube auf die Außenseite des Oberschenkel knochens überträgt. In ähnlichen Ausführungen werden einfache Knochenschrauben verwendet, die auf den großen Trochanter einwirken (DE-PS 28 51 598, DE-AS 25 30 254). In diesen Fällen erfolgt die Verdrehsicherung der Prothese durch die starren Zugglieder, wenn sie nicht schon durch eine Verankerung mittels Knochenzement gewährleistet ist. Ferner ist es bekannt (DE-OS 31 25 658), ein flexibles Zugglied zu verwenden, wobei die Frage der Verdrehsicherung nicht angesprochen ist und wahrscheinlich durch Zement verankerung bewirkt werden soll.It is known (DE-OS 28 32 555) that one in the area of proximal end of the shaft overloading the medial and a relief of the lateral bone areas, both for a regression of the bone tissue and thus for a Loosening of the prosthesis can be responsible, thereby ver can avoid or reduce the proximal forces End of the shaft by means of a so-called tension band on the lateral and distal parts of the bone derives. A screw, for example, can be used as the tension band be used that depend on the proximal of the shaft closing platen to a distal of the large one Trochanter arranged plate that leads the train there by force of the screw on the outside of the thigh transmits bone. In similar designs simple bone screws used on the big ones Act trochanter (DE-PS 28 51 598, DE-AS 25 30 254). In these cases, the prosthesis is secured against rotation through the rigid tension members, if not already through anchoring with bone cement is guaranteed. It is also known (DE-OS 31 25 658), a flexible To use tension member, the question of the anti-rotation is not addressed and probably by cement anchoring should be effected.
Es hat sich jedoch gezeigt, daß die Verwendung von Knochen zement bestimmte Nachteile hat, insbesondere bei jüngeren Patienten. Eine zementfreie Implantation wird daher weit gehend angestrebt. Da hierbei die durch den Zement sonst gewährleistete Drehsicherung entfällt, ist man bei Zug gurtungsprothesen auf solche angewiesen, bei denen ein starr und drehfest mit der Prothese verbundenes Zugglied verwendet wird, das dann die Aufgabe der Drehsicherung übernimmt. Jedoch ist auch dies nicht ohne Nachteil, weil gerade bei zementfreier Implantation die Position der Prothese im Knochen nicht ein für allemal feststeht, sondern mit einem Setzen der Prothese gerechnet werden muß, was mit Relativbewegungen verbunden ist, die im Be reich eines starren Zugglieds zu schwer vorhersehbaren Verhältnissen führen können.However, it has been shown that the use of bones cement has certain disadvantages, especially among younger people Patient. A cementless implantation is therefore becoming wide aimed at going. Since this is otherwise due to the cement guaranteed rotation lock is no longer available, you are in Zug Belt prostheses rely on those where a rigid and non-rotatably connected tension member with the prosthesis is used, which then the task of the rotation lock takes over. However, this is also not without disadvantage because the position of the Prosthesis in the bone is not fixed once and for all, but to be expected to put the prosthesis must what is connected with relative movements that in Be range of a rigid tension member to difficult to predict Conditions can lead.
Der Erfindung liegt daher die Aufgabe zugrunden, die Möglichkeit der Zuggurtungs-Prothese auch bei zementfreier Implantation zu bewahren. The invention is therefore based on the object Possibility of tension belt prosthesis even with cementless Preserve implantation.
Die erfindungsgemäße Lösung besteht darin, daß die Ver bindung des Zugglieds mit dem Prothesenschaft winkelbe weglich ist und an der Prothese mindestens ein Vorsprung bzw. eine Ausnehmung zum drehsichernden gegenseitigen Ein griff mit dem Oberschenkelknochen vorgesehen ist.The solution according to the invention is that the Ver binding of the tension member with the prosthesis socket winkelbe is movable and at least one projection on the prosthesis or a recess for rotationally locking mutual one handle with the thigh bone is provided.
Der Erfindungsgedanke umfaßt die oben geschilderte Er kenntnis von dem nachteiligen Einfluß der starren Zug gliedverbindung mit der Prothese bei deren Setzbewegung. Die Lösung bewahrt die Vorteile, die mit der Verwendung starrer Zugglieder und mit der dadurch ermöglichten, ein deutigen Positionierung gegeben sind, ohne deren Nach teile in Kauf nehmen zu müssen.The inventive concept includes the Er described above knowledge of the adverse influence of rigid train limb connection with the prosthesis during its setting movement. The solution preserves the benefits of using it rigid tension members and with the thereby made possible clear positioning are given, without their after having to put up with parts.
Zweckmäßigerweise wird die winkelbewegliche Verbindung des Zugglieds mit dem Prothesenschaft durch eine sphärische Ausbildung der Kraftübertragungsfläche erzielt, wobei diese nicht nur prothesenseitig, sondern auch am prothesenfernen Ende vorgesehen sein kann, nämlich zwischen dem Zugglied und einer dieses an dem Oberschenkelknochen abstützenden Platte. Die Drehsicherung kann mittels bekannter Einrichtungen erfolgen. Besonders vorteilhaft ist ein in einen Knochenaus schnitt eingreifender Vorsprung am proximalen Schaftende, der vorzugsweise an der Unterseite einer zumindest medial vorgesehenen Knochenauflage angeordnet ist.The angularly movable connection is expediently of the tension member with the prosthesis socket by a spherical Formation of the power transmission surface achieved, this not only on the prosthesis side, but also on the prosthesis away End can be provided, namely between the tension member and one that supports it on the thigh bone Plate. The rotation lock can be made using known devices respectively. A bone out is particularly advantageous cut engaging protrusion at the proximal end of the shaft, preferably on the underside of an at least medial provided bone support is arranged.
Die Erfindung wird im folgenden näher unter Bezugnahme auf das in der Zeichnung dargestellte Ausführungsbeispiel er läutert. Darin zeigen:The invention will now be described in more detail with reference to the embodiment shown in the drawing he purifies. In it show:
Fig. 1 eine schematische Seitenansicht und Fig. 1 is a schematic side view
Fig. 2 eine Ansicht in Pfeilrichtung X. Fig. 2 is a view in the direction of arrow X.
Der in bekannter Weise gestaltete Prothesenschaft 1 trägt an seinem proximalen Ende Einrichtungen 2 zur Verbindung mit einem Prothesenkopf. Medial ist der Schaft durch eine überkragende Knochenauflage 3 abgeschlossen, die dazu be stimmt ist, sich auf die Resektionsfläche 4 des strich punktiert angedeuteten Knochens 5 aufzulegen. Im lateralen Bereich 6 des proximalen Schaftendes befindet sich eine Bohrung 7, die proximal durch eine sphärische Einsenkung 8 abgeschlossen ist. Hindurchgesteckt ist ein Schraubbolzen 9, der darin durch eine Mutter 10 gesichert ist, die sich über eine passend zur Einsenkung 8 sphärische Unterlegscheibe 11 abstützt. Die Bohrung 7 ist im Vergleich zum Durchmesser des Bolzens 9 weit ausgeführt, so daß dieser gewisse Winkel bewegungen ausführen kann, wie sie im Zusammenhang mit dem Setzen der Prothese im Knochen erforderlich werden können.The prosthesis socket 1, which is designed in a known manner, carries devices 2 for connection to a prosthesis head at its proximal end. Medially, the shaft is closed by a cantilevered bone support 3 , which is intended to be placed on the resection surface 4 of the bone 5 indicated by dash-dotted lines. In the lateral area 6 of the proximal end of the shaft there is a bore 7 which is closed proximally by a spherical depression 8 . A screw bolt 9 is inserted through it, which is secured therein by a nut 10 which is supported by a washer 11 which is spherical to match the countersink 8 . The bore 7 is carried out in comparison to the diameter of the bolt 9 , so that this can perform certain angular movements, as may be necessary in connection with the setting of the prosthesis in the bone.
Am anderen Ende ist der Bolzen 9 durch einen sphärischen Kopf 12 abgeschlossen, der in einer entsprechend sphärischen Einsenkung 13 einer Platte 14 liegt, die zur Übertragung der Kraft auf die Außenseite des Knochens im distalen Bereich des großen Trochanter dient.At the other end, the bolt 9 is closed off by a spherical head 12 which lies in a correspondingly spherical depression 13 of a plate 14 which serves to transmit the force to the outside of the bone in the distal region of the large trochanter.
Unter der Knochenauflage 3 ist medial ein Vorsprung 15 vor gesehen, der in eine entsprechende Ausfräsung 16 des Knochens eingreift und zusammen mit dieser die Drehsicherung bildet.A projection 15 is seen medially under the bone support 3 , which engages in a corresponding milling 16 of the bone and together with this forms the rotation lock.
Die sphärische Unterlegscheibe 11 besteht zweckmäßigerweise aus Kunststoff zur Verminderung der Reibung. Dasselbe gilt für die Platte 14.The spherical washer 11 is suitably made of plastic to reduce friction. The same applies to plate 14 .
