Abstract

In an acetabular prosthesis for left hip joints provided on its circumference with a screw thread (3) for anchorage in the pelvic bone, the screw thread (3) is designed as a lefthanded screw thread in order to increase the durability of the seat of the prosthesis in the bone. <IMAGE>

Description

"HUftgelenkpfannen-Prothese" "Hip joint socket prosthesis"

Die Erfindung betrifft eine Hüftgelenkpfannen-Prothese für linksseitige Hüftgelenke mit einer Gelenkpfanne, die an ihrem Umfang mit einem Gewinde zur Verankerung der Prothese im Beckenknochen versehen ist.The invention relates to an acetabular cup prosthesis for the left side Hip joints with a joint socket that is threaded on its circumference for anchoring the prosthesis is provided in the pelvic bone.

Hüftgelenkpfannen-Prothesen der vorstehenden Art werden ausschließlich mit Rechtsgewinde geliefert, und zwar unabhängig davon, ob sie für das rechts- oder linksseitige Hüftgelenk bestimmt sind.Acetabular socket prostheses of the above type are exclusively Supplied with right-hand thread, regardless of whether they are for right-hand or left hip joint are determined.

Es hat sich gezeigt, daß Hüftgelenkpfannen-Prothesen der in Betracht gezogenen Art dazu neigen, sich im Laufe der Zeit zu lockern. Beobachtungen der Anmelderin geben zu der Vermutung Anlaß, daß die Lockerungserscheinungen mit den unterschiedlichen Belastungen der Prothese beim Vorwärts- und Rückwärtsbewegen des Beines zusammenhängen. Allem Anschein nach erscheint die Annahme gerechtfertigt, daß die Gefahr eines Lockerwerdens der Prothese besonders groß ist, wenn in ein linksseitiges Hüftgelenk eine Prothese mit Rechtsgewinde eingesetzt wird.It has been shown that acetabular cup prostheses of the Drawn species tend to loosen up over time. Observations of the Applicants give rise to the assumption that the loosening phenomena with the different loads on the prosthesis when moving the Related. From all appearances the assumption seems justified that the risk of loosening the prosthesis is particularly great when in a On the left hip joint a prosthesis with a right-hand thread is used.

Der Erfindung liegt die Aufgabe zugrunde, die Dauerhaftigkeit des festen Sitzes einer Hüftgelenkpfannen-Prothese für linksseitige Hüftgelenke zu verbessern. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das zur Verankerung der Prothese im Beckenknochen dienende Gewinde als Linksgewinde ausgebildet ist.The invention is based on the object of improving the durability of the To improve the firm fit of an acetabular cup prosthesis for left hip joints. This object is achieved according to the invention in that the anchoring of the prosthesis in the pelvic bone serving thread is designed as a left-hand thread.

Die erfindungsgemässe Hüftgelenkpfannen-Prothese bietet den Vorteil, daß die beim Zurückbewegen des Beines in die Hüftgelenkpfannen-Prothese eingeleiteten Reibungsmomente, welche die Reibungsmomente bei der Vorwärtsbewegung des Beines übersteigen, nicht im Sinne einer Lockerung sondern im Sinne eines sich Festziehens der Prothese auf diese einwirken.The acetabular cup prosthesis according to the invention offers the advantage that the introduced into the acetabular cup prosthesis when the leg was moved back Frictional moments, which are the frictional moments when the leg moves forward exceed, not in the sense of a loosening but in the sense of a tightening the prosthesis act on this.

Es versteht sich, daß für rechtsseitige Hüftgelenke auch in Zukunft Hüftgelenkpfannen-Prothesen mit Rechtsgewinde verwendet werden sollten.It goes without saying that for right hip joints also in the future Right-hand threaded acetabular cup prostheses should be used.

Das Gewinde der Prothese kann in bekannter Weise mehrgängig und/oder als Schneidgewinde ausgebildet sein.The thread of the prosthesis can be multi-thread and / or in a known manner be designed as a cutting thread.

Die Erfindung wird im folgenden anhand eines in der beigefügte Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen: Fig. 1 die Seitenansicht einer Hüftgelenkpfanne und Fig. 2 einen Schnitt durch die Pfanne gemäß Fig. 1.The invention is described below with reference to one in the accompanying drawing illustrated embodiment explained in more detail. 1 shows the side view an acetabular cup and FIG. 2 shows a section through the socket according to FIG. 1.

In den Figuren ist eine HUftgelentpSanne dargestellt, die aus einem Kunststoffinnenteil 1 und einem metallischen Schneidring 2 besteht. Der Schneidring 2 trägt außen ein Gewinde 3, dessen Gänge durch Schneidnuten 4 unterteilt sind. Das Gewinde 3 ist als mehrgängiges Linksgewinde ausgebildet.In the figures, a hip gel relaxation is shown, which consists of a Plastic inner part 1 and a metallic cutting ring 2 consists. The cutting ring 2 carries a thread 3 on the outside, the threads of which are divided by cutting grooves 4. The thread 3 is designed as a multiple left-hand thread.
