Description
tragfähig, ausgebildet ist, besteht in bekannter Weise aus einer körperverträglichen Metallegierung oder aus einem ebenfalls physiologisch unbedenklichen Kunststoff. Ihre kugelkalottenförmige, innere Ausnehmung 2 (Fig. 1) dient zur Aufnahme eines nichtgezeigten Gelenkkopfes.stable, is formed, consists in a known manner of a body-compatible Metal alloy or made of a likewise physiologically harmless plastic. Your spherical cap-shaped, inner recess 2 (Fig. 1) is used for Recording of a joint head (not shown).
Ihre äußere Verkankerungsfläche 3 ist in bekanntcr Weise mit Rippen 4 versehen, die nach der Verankerung Relativbewegungen zwischen der Pfanne 1 und dem auf sie aufgebrachten Material - bisher im allgemeinen einem Knochenzement, im vorliegenden Fall aber einem hochelastischen Zwischenmaterial 5 (F i g. 3 und 4)~verhindern sollen. Um die Verankerung des Zwischenmaterials auf der Fläche 3 zu verbessern, sind als Verankerungselemente in verschiedenem Abstand vom Rand in Umfangsrichtung verlaufende Drahtringe 8 an den Rippen 4 befestigt z. B. angelötet. Its outer anchoring surface 3 is ribbed in a known manner 4 provided, the relative movements between the pan 1 and after the anchoring the material applied to it - so far generally a bone cement, in the present case, however, a highly elastic intermediate material 5 (FIGS. 3 and 3) 4) ~ should prevent. Around the anchoring of the intermediate material on the surface 3 are to be improved as anchoring elements at different distances from the edge in Circumferential wire rings 8 attached to the ribs 4, for. B. soldered.
Wie F i g. 3 und 4 zeigen. ist die Verankerungsfläche 3 mit dem hochelastischen Material 5 überzogen. Dieses ist z. B. ein Silikonkautschuk. Auf ihrer Außenfläche ist die Kautschukschicht ihrerseits mit Rillen 6. die in Umfangsrichtung und in Meridianrichtung verlaufen, und mit Vertiefungen 7 versehen. Like F i g. 3 and 4 show. is the anchoring surface 3 with the highly elastic Material 5 coated. This is e.g. B. a silicone rubber. On their outer surface is the rubber layer in turn with grooves 6th in the circumferential direction and in Run the meridian direction, and provided with depressions 7.
Das Aufbringen der Kautschukmasse auf die Verankerungsfläche 2 erfolgt beispielsweise so, daß zunächst die Pfanne 1 in gewissem Abstand von einer das Negativ der Außenfläche der Schicht 5 bildenden Form fixiert wird. Der mit dem zugehörigen Katalysator oder Vernetzer im vorgeschriebenen Verhältnis von beispielsweise 1: 10 innig vermischten Silikonkautschuk wird dann in die Form eingebracht. z. B. The rubber compound is applied to the anchoring surface 2 for example, so that first the pan 1 at a certain distance from one of the negative the mold forming the outer surface of the layer 5 is fixed. The one with the associated Catalyst or crosslinker in the prescribed ratio of, for example, 1: 10 intimately mixed silicone rubber is then placed in the mold. z. B.
eingegossen. Die Fließfähigkeit kann dabei notfalls mit Hilfe eines Verdünners erhöht werden.poured. The flowability can if necessary with the help of a Thinner.
Der erwähnte Silikonkautschuk polymerisiert bzw. The mentioned silicone rubber polymerizes or
vulkanisiert bei Raumtemperaturen von 25 C innerhalb von 24 Std. nach der Zugabe des Katalysators aus, wodurch eine feste Verankerung zwischen der Pfanne I und der Schicht 5 entsteht. Durch Anwendung höherer Temperaturen läßt sich die Aushärtung der elastischen Schicht erheblich beschleunigen. Bei Raumtemperaturen erreicht der genannte Kautschuk dann seine Endhärte von etwa Shore A35 bis 45 nach einigen Tagen.vulcanizes at room temperatures of 25 C within 24 hours the addition of the catalyst, creating a firm anchor between the pan I and layer 5 is created. By using higher temperatures, the Significantly accelerate the hardening of the elastic layer. At room temperatures the said rubber then reaches its final hardness of approximately Shore A35 to 45 some days.
Nach Erreichen der Endhärte des Zwischenmaterials 5 kann die Pfanne 1 in üblicher Weise mit einem der bekannten Knochenzemente 12 (F i g. 5), z. B. After the intermediate material 5 has reached its final hardness, the pan can 1 in the usual way with one of the known bone cements 12 (FIG. 5), e.g. B.
mit Nlethyimetacrylat, im Beckenknochen 10 verankert werden. Der Knochenzement 12 der im Becken in künstliche, das dichtere Knochengewebe durchstoßende Ausnehmungen 11 fließt und so Verankerungszapfen 13 bildet, dringt dabei andererseits in die Rillen 6 und die Vertiefungen 7 ein, so daß sich eine ebenfalls feste und besonders gegen Drehung und gegen Verschiebungen längs der Außenfläche der Schicht 5 widerstandsfähige Verbindung zwischen der Schicht 5 und dem Knochenzement 12 ergibt.with methyl methacrylate, anchored in the pelvic bone 10. The bone cement 12 of the in the pelvis in artificial, the denser bone tissue penetrating recesses 11 flows and so forms anchoring pin 13, on the other hand penetrates into the Grooves 6 and the depressions 7, so that it is also solid and special resistant to rotation and displacement along the outer surface of the layer 5 Connection between the layer 5 and the bone cement 12 results.
Die schwingungsdämpfende Wirkung der neuartigen Zwischenschicht 5 beruht höchstwahrscheinlich auf den sehr großen Unterschieden in den Elastizitätsmoduln der Pfanne 1. den Komponenten ihrer Verankerung und des Knochens. In dem beschriebenen Beispiel betragen diese Moduln in kptmm- für die Metallpfanne etwa 20 000, für die Schicht 5 etwa 2 bis 3, für den Knochenzement etwa 100 bis 200 und für den Knochen selbst etwa 1000. Dabei dürfte besonders an der Grenzfläche zwischen der Schicht 5 und dem Knochenzement 12 eine Weitergabe der Schwingungsenergie aus dem sehr weichen Silikonkautschuk an den weniger elastischen Knochenzement 12 praktisch nicht mehr stattfinden. The vibration-damping effect of the new intermediate layer 5 is most likely due to the very large differences in the moduli of elasticity the socket 1. the components of its anchorage and the bone. In the described For example, these modules in kptmm- for the metal pan are around 20,000, for the Layer 5 about 2 to 3, for the bone cement about 100 to 200 and for the bone even about 1000. It should be especially at the interface between the layer 5 and the bone cement 12 a transmission of the vibration energy from the very soft Practically no more silicone rubber on the less elastic bone cement 12 occur.
