Beschreibung:Description:

1. Bezeichnung des Anmeldungsgegenstandes:1. Designation of the subject of the application:

Zementlose Rotationsstabile Kompressions-Hüftendoprothese (Im folgenden "ZRK-Prothese" genannt).Cementless, rotationally stable compression hip prosthesis (hereinafter referred to as "ZRK prosthesis").

2. Zweck der Erfindung:2. Purpose of the invention:

Der Zweck der Erfindung ist der Ersatz eines defekten oder unbrauchbar gewordenen Hüftkopfes beim Menschen durch eine ZRK-Prothese.The purpose of the invention is to replace a defective or unusable one femoral head that has become in humans through a ZRK prosthesis.

3. Stand der Technik:3. State of the art:

Seit Ende der fünfziger Jahre sind für den Ersatz beim Menschen verschiedene Hüfttotalendoprothesen-Systeme bekannt. Bei den bekanntesten Systemen handelt es sich um Hufttotalendoprothesen, deren Verankerung mittels eines in der Hüfttotalendoprothese integrierten Prothesenstiels im Oberschenkel erfolgt. Es gab verschiedene Untersuchungen und experimentelle Ansätze femorale Implantate zu entwickeln, die zum Teil implantiert wurden, grösstenteils nach Erfolglosigkeit der Ergebnisse jedoch wieder verlassen wurden. Als Beispiel hierfür gelten: Modell der Norwich School (1940), Modell von Wiles (1938). Die Zuggurtungsprothese von Ritter (1976) ist eine Neuentwicklung.Since the late fifties, there have been different ones for replacement in humans Total hip replacement systems known. The most well-known systems are total hip prostheses, which are anchored by means of a prosthetic stem integrated in the total hip endoprosthesis takes place in the thigh. There have been various investigations and experimental ones Approaches to develop femoral implants, some of which were implanted, but mostly again after unsuccessful results were left. The following are examples of this: the Norwich School model (1940), the Wiles model (1938). The tension belt prosthesis from Ritter (1976) is a new development.

Es wurde eine Zementlose, Rotationsstabile Kompressionshüftendoprothese (ZRK-Prothese) entwickelt, die den physiologischen Spannungsverläufen des lebenden Knochens in Grosse und Richtung weitgehendst folgt. Weiterhin sollte die Lockerung des eingebrachten Implantates durch ausreichend hohe Vorspannung bzw. ausreichend hohe Kompression verhindert werden.It became a cementless, rotationally stable compression hip prosthesis (ZRK prosthesis) that largely follows the physiological tension curves of the living bone in terms of size and direction. Farther the loosening of the inserted implant should be prevented by sufficiently high pre-tensioning or sufficiently high compression.

In den Schenkelhalsstumpf wird der aus Prothesenhals, Prothesenkragen, Stabilisierendem Antirotationskörper und Prothesenhülse bestehenden oberen ZRK-Prothesenteil eingebracht. Der Prothesenkragen liegt nach exakter Resektion des Hliftkopfes mittels des neu entwickelten, kombinierten Ziel- und Resektionsgerätes plan an der Schenkelhalsstumpfkortikalis auf. Hierdurch ist eine direkte Kraftleitung in den Femur gewährleistet, da die physiologischen Spannungsverläufe im Schenkelhalsstumpf und proximalen Femur erhalten bleiben. Die Kompressionsschraube stellt die kraftschlüssige Verbindung zwischen der am Femur fixierten ZRK-Platte und dem oberen ZRK-Prothesenteil her. Die Kompressionsschraube gewährleistet nach dem Anziehen eine ausreichend hohe Kompression bzw. Vorspannung zwischen der ZRK-Platte und dem Prothesenkragen, um Relativbewegungen bzw. Nulldurchgang am Implantat zu vermeiden.The prosthesis neck, prosthesis collar, Stabilizing anti-rotation body and existing prosthesis sleeve Inserted the upper central part of the prosthesis. The prosthesis collar is behind exact resection of the Hlift head using the newly developed, combined Aiming and resection device flat on the femoral stump cortex on. This ensures a direct transmission of force into the femur, since the physiological tension curves in the femoral neck stump and proximal Femur are preserved. The compression screw provides the force-fit connection between the ZRK plate fixed to the femur and the upper part of the ZRK prosthesis. The compression screw ensures a sufficiently high compression or pretensioning after tightening between the ZRK plate and the prosthesis collar to prevent relative movements or zero crossing on the implant.

Der keilförmige, ovale Antirotationskörper, der sich dem Prothesenkragen anschliesst, wird in den Schenkelhalsstumpf eingelassen. Durch seine ovale Formgebung, die den anatomischen Verhältnissen nachgebildet wurde, legt er sich an der inneren Kortikalis und der Spongiosa im Schenkelhalsstumpf an. Hierdurch ist eine Rotationsstabilität der ZRK-Prothese sichergestellt. The wedge-shaped, oval anti-rotation body attached to the prosthetic collar is inserted into the femoral neck stump. Due to its oval shape, which was modeled on the anatomical conditions, it rests against the inner cortex and the cancellous bone in the femoral neck stump. This ensures that the ZRK prosthesis is rotationally stable.

Die Führungshülse ist in dem Zylinder, der in einem Winkel von 135 Grad mit der ZRK-Platte verbunden ist, gelagert. Hierdurch erfährt der obere ZRK-Prothesenteil zum einen die exakte Richtungsvorgabe, zum anaeren die erforderliche Stabilität.The guide sleeve is in the cylinder, which is at an angle of 135 degrees is connected to the ZRK plate, stored. As a result, the upper ZRK prosthesis part is given the exact direction on the one hand, and on the other hand the required stability.

Die ZRK-Platte wird durch zwei oder mehrere Kortikalisschrauben am lateralen proximalen Femur fixiert.The ZRK plate is attached to the lateral by two or more cortex screws proximal femur fixed.

An der femoralen Berührungsfläche ist die ZRK-Platte konkav geformt zur exakten Adaption an den Femur. Sämtliche Kanten der ZRK-Platte sind zur Vermeidung iatrogen gesetzter Traumen abgerundet. Am Übergang von Teil 1 zu Teil 2 ist das Widerlager für die Kompressionsschraube eingearbeitet. Die Andruckfläche des Widerlagers ist entsprechend der Kopfform der Kompressionsschraube ausgebildet, um eine optimale Flächenpressung bei der erforderlichen Vor).ast zV* Vermeidung von Relativbewegungen und Nulldurchgang zu erreichen.Part 1 shows the CRC plate, which is secured with two cortical screws laterally is fixed on the femur and the opposite cortex under compression. The ZRK plate is concave on the femoral contact surface for exact adaptation to the femur. All edges of the ZRK plate are rounded to avoid iatrogenic trauma. At the transition from Part 1 of Part 2 includes the abutment for the compression screw. The contact surface of the abutment corresponds to the shape of the head The compression screw is designed to achieve an optimal surface pressure with the required pre) .ast zV * Avoidance of relative movements and to achieve zero crossing.
