Description

Knochengelenk-Prothese Seit einiger Zeit hat man festgestellt, daß sich Methacrylmethylester für Knochenprothesen gut eignet, weil sich der Organismus diesem Kunstharz gegenüber vollkommen tolerant verhält. Allerdings treten bisher noch Mängel auf, die durch ungenügendes Haften und demzufolge ungenügendes Festsitzen der Prothese in ihrem Knochenbett bedingt sind. Das kommt daher, daß der Schaft bei den bisher verwendeten Prothesen glatt ist und nur dann richtig haftet, wenn sein pyramidenstumpffirmiges winde den Knochen vollkommen berührt.Bone Joint Prosthesis For some time it has been found that Methacrylmethylester is well suited for bone prostheses because the organism is completely tolerant of this synthetic resin. However, so far occur There are still defects caused by insufficient adhesion and consequently insufficient attachment of the prosthesis in their bone bed. This is because the shaft is smooth with the previously used prostheses and only adheres properly if its truncated pyramidal shape touches the bone completely.

Da jedoch eine genane Längenbemessung vor der Operation schwierig ist, kommt es oft vor, daß dieses pyramidenstumpfförmige Ende nur teilweise oder zu weit in den Knochen eingelassen wird.However, it is difficult to precisely measure the length before the operation is, it often happens that this frusto-pyramidal end is only partially or is inserted too far into the bone.

Nach der Erfindung wird an Stelle eines glatten zylindrischen Prothesenschaftes ein im Querschnitt sternförmiger Schaft benutzt, der als gerillter Stab mit der ihn umgebenden Knochenmasse verwächst. According to the invention, instead of a smooth cylindrical prosthesis shaft a shaft with a star-shaped cross-section is used, which is a grooved rod with the surrounding bone grows together.

Die Erhöhungen und Vertiefungen des Prothesenschaftes ergeben Unebenheiten, die bei auftretenden Druckbeanspruchungen ein Gleiten der Prnthese in dem porösen Knochengewebe verhindern. Außerdem wird durch die Längsrippen die den Knochen berührende Oberfläche vergrößert, wodurch ein besseres Haften und auch eine bessere Frestigkeit der I>rothese erzielt wird.The elevations and depressions of the prosthesis shaft result in unevenness, the sliding of the prosthesis in the porous when pressure loads occur Prevent bone tissue. In addition, the longitudinal ribs that form the bone touching The surface area is enlarged, resulting in better adhesion and also better stability the prosthesis is achieved.

Vorzugsweise wird der Schaft der Prothese so ausgebildet, daß die Prothese sowohl gegen axiale Verschiebung als auch gegen Drehen gesichert ist. Preferably, the shaft of the prosthesis is designed so that the Prosthesis is secured against both axial displacement and rotation.

Hierfür kann der Prothesenschaft ganz oder teilweise mit reliefartigen Ansätzen oder Vertiefungen versehen sein, die seine Berührungsfläche mit dem Knochen vergrößern und das Verwachsen der Prothese mit dem Knochen begünstigen. Die reliefartigen Ansätze oder Vertiefungen können punktartig als Warzen oder Einsenkungen ausgeführt oder als Leisten oder Nuten linienförmig begrenzt sein und zu den Erzeugenden der verschiedenen Oberflächen der Prothese parallel oder nicht parallel liegen. also in Längsrichtung ring- oder schraubenförmig angeordnet sein.For this purpose, the prosthesis shaft can be completely or partially with relief-like Approaches or depressions should be provided that its contact surface with the bone and encourage the prosthesis to grow together with the bone. The relief-like Approaches or depressions can be designed as warts or depressions or be delimited as strips or grooves in a linear manner and to the generators of the different surfaces of the prosthesis are parallel or non-parallel. so be arranged in a ring or helical shape in the longitudinal direction.

Ist die Prothese mit einer inneren Metallarmatur versehen, so kann diese Armatur eine gleichartige Form aufweisen, damit das sie umgehende Material etwa die gleiche Stärke hat. If the prosthesis is provided with an internal metal armature, it can this fitting have a similar shape, so that they bypassing material has about the same strength.

I)ie 1> sherigen Gelenkprothesen bestehen aus einem kugeligen Kopf 1 und einem glatten zylindrischen Schaft 2, dessen unteres Ende pyramidenstumpfförmig zuläuft. I) The 1> sherigen joint prostheses consist of a spherical Head 1 and a smooth cylindrical shaft 2, the lower end of which is truncated pyramidal runs in.

Abweichend hiervon weist nach Fig. 2 bis 4 der Schaft 2 auf seinem Umfang Längsrippen 4 auf. Dabei kann er entweder mit einem pyramidenförmigen Ende 5 (Fig. 2) oder mit einem kegelförmigen Ende 6 (Fig. 4) versehen sein. Ein pyramidenförmiges Ende, das bisher ein Drehen der Prothese verhindern sollte, ist wegen der den gleichen Zweck erfüllenden Riffelung an sich nicht mehr erforderlich Gestalt, Zahl und Stärke der Rippen sind beliebig. Notwithstanding this, according to FIGS. 2 to 4, the shaft 2 has on its Circumference longitudinal ribs 4 on. He can either with a pyramid-shaped end 5 (Fig. 2) or with a conical end 6 (Fig. 4). A pyramidal one End, which so far was supposed to prevent the prosthesis from rotating, is the same because of the Purpose-fulfilling corrugation in itself no longer required shape, number and strength the ribs are arbitrary.

Sie können z. B. kantig (Fig. 3) oder abgerundet sein (Fig. 5).You can e.g. B. angular (Fig. 3) or rounded (Fig. 5).

Nach Fig. 6 und 7 weist der Prothesenschaft 7 warzenartige Ansätze 8 auf. Der in Fig. 8 und g dargestellte Schaft g lat dagegen Vertiefungen 10. According to FIGS. 6 and 7, the prosthesis shaft 7 has wart-like extensions 8 on. The shaft shown in FIGS. 8 and g, on the other hand, has depressions 10.

Der Schaft 11 nach Fig. 10 und 11 vereinigt beide vorhergehenden Ausführungen. Er weist nämlich vorstehende Ansätze 12 und in geeigneter Weise dazu versetzt liegende Einsetikungen I3 auf.The shaft 11 according to FIGS. 10 and 11 combines both of the preceding versions. This is because it has protruding lugs 12 and appropriately offset thereto Inserts I3 on.

Bei der Ausführung nach Fig. 12 ist der Schaft 14 an seiner Oberfläche mit Längsnuten 15 versehen, die nicht bis zum Schaftende durchlaufen. Auf diese Weise bilden die unteren Enden 16 dieser Nuten Anschläge, die sich einer axialen Verschiebung des Schaftes widersetzen, während die Nuten selbst das Verdrehen des Schaftes im Knochen verhindern. In the embodiment according to FIG. 12, the shaft 14 is on its surface provided with longitudinal grooves 15 which do not run through to the end of the shaft. To this Way, the lower ends 16 of these grooves form stops that are axial Resist displacement of the shank, while the grooves themselves prevent the twisting of the Prevent shaft in the bone.

Bei der Prothese nach Fig. 14 weist der Schaft I7 Ringnuten I8 und Längsnuten 19 auf. DieLängsnuten verhindern das Drehen und die Ringnuten das axiale Verschieben des Schaftes im Knochen. In the prosthesis according to FIG. 14, the shaft I7 has annular grooves I8 and I Longitudinal grooves 19. The longitudinal grooves prevent turning and the annular grooves prevent the axial Moving the shaft in the bone.

Fig. 16 zeigt eine Ausführung, bei der die Ringnuten der zuvor beschriebenen Prothese durch eine Schraubennut (Gewindegang) ersetzt sind. Fig. 16 shows an embodiment in which the annular grooves of the previously described Prosthesis are replaced by a screw groove (thread).

Die Prothese nach Fig. 17 trägt an ihrem Schaft 21 Rippen 22, deren obere Enden Anschläge gegen Axialverschiebung bilden, während die Rippen selbst ein Verdrehen der Prothese im Knochen verhindern. Dem gleichen Zveck dienen die an der Innenfläche des halbkugeligen Kopfes 23 befindlichen Rippen 24. Das untere Ende des Schaftes ist bei 25 gezahnt, um den Widerstand gegen Axialverschiebung zu erhöhen. The prosthesis according to FIG. 17 carries on its shaft 21 ribs 22, the upper ends form stops against axial displacement, while the ribs themselves prevent the prosthesis from twisting in the bone. They serve the same purpose located on the inner surface of the hemispherical head 23 ribs 24. The lower End of the shaft is serrated at 25 to resist axial displacement to increase.
