PATENTANSPRÜCHE
1. Gelenkprothese, die ein zum Aufsetzen auf und Befestigen an einem natürlichen Gelenkkopf eingerichtetes Hohlelement mit kugeliger Aussenoberfläche aufweist, dadurch gekennzeichnet, dass das Hohlelement eine Vielzahl von über seiner Aussenoberfläche verteilten, es in seiner ganzen Wandstärke durchsetzenden Löchern besitzt.
2. Gelenkprothese nach Anspruch 1, dadurch gekennzeichnet, dass die Löcher insgesamt mindestens 50% der Aus senoberfläche einnehmen.
Die Erfindung betrifft eine Gelenkprothese, die ein zum Aufsetzen auf und Befestigen an einem natürlichen Gelenkkopf eingerichtetes Hohlelement mit kugeliger Aussenoberfläche aufweist.
Bis jetzt wurden die defekten Gelenkteile entfernt und durch ein nicht körpereigenes Material, wie Metall, Kunststoff, Keramik usw., mittels Knochenzement oder Verschraubung, ersetzt. Es wurde also eine Ersatzprothese eingesetzt. Es leuchtet nun ein, dass der Heilprozess nach dem Einoperieren einer Ersatzprothese recht lange andauert.
In Fachkreisen weiss man, dass es recht oft, und zwar sowohl bei gewissen Erkrankungen wie auch bei gewissen unfallbedingten Gelenkbeschädigungen, genügt, nur oberflächlich defekte Gelenkteile zu ihrer ursprünglichen Form hin zu ergänzen und dem Knochen das Aufbauen zu erleichtern dadurch, dass Belastungen von Stellen ferngehalten werden, die bei Gelenkbewegungen auf gegenüberliegenden Gelenkflächen gleiten müssen. Ein typischer derartiger Fall liegt vor bei einer Hüftgelenk-Arthrose.
In solchen Fällen hat man schon Gelenkprothesen gemäss Oberbegriff von Anspruch 1 auf den natürlichen Gelenkkopf aufgesetzt und an ihm befestigt.
Der Erfindung lag nun die Aufgabe zugrunde, eine Gelenkprothese dieser Art zu schaffen, die in solchen Fällen mit Erfolg eingesetzt Werden kann und einen rascheren Heilprozess ermöglicht. Somit handelt es sich um die Schaffung einer verbesserten Schalenprothese, die das nachträgliche Aufbauen durch natürliche Heilprozesse erheblich erleichtert und damit die Heilung erheblich fördert.
Im Sinne der Lösung dieser Aufgabe sieht die Erfindung vor, dass das Hohlelement eine Vielzahl von über seiner Aussenoberfläche verteilten, es in seiner ganzen Wandstärke durchsetzenden Löchern besitzt.
Da eine typische Anwendung der Erfindung bzw. Ausführungsform der erfindungsgemässen Prothese eine solche ist, wird die Erfindung anhand beiliegender Zeichnung beispielsweise an einer Hüftgelenkprothese erläutert. Es sei aber ausdrücklich darauf hingewiesen, dass die Erfindung mit ebensoviel Erfolg auch an anderen Gelenkprothesen anwendbar bzw.
verkörperbar ist. Es zeigen
Fig. 1 einen Aufriss eines Femurknochens mit einer an dessen Gelenkkopf angebrachten Ausführungsform der erfindungsgemässen Prothese, die teilweise im Schnitt veranschaulicht ist, und die Fig. 2a, 2b, 2c, 2d und 2e Ausführungsvarianten, die sich vom Ausführungsbeispiel nach Fig. 1 nicht hinsichtlich der erfindungsgemässen Ausbildung, sondern hinsichtlich der an sich bekannten Anbringungsarten am Femurkopf unterscheiden.
In Fig. list mit 1 ein natürlicher Femurknochen, mit 1a dessen Gelenkkopf und mit 2 der Hauptteil der Stütz- und Formgebungsprothese bezeichnet. Bei diesem handelt es sich um ein teilkugeliges Hohlelement aus einem körperverträglichen Material wie schon die bekannten Gelenkprothesen. Die kugelige Form ist, wie auch schon bei bekannten Ausführungen, dem Femurkopf la angepasst. Neu ist nun, dass dieses Hohlelement 2 mit einer Vielzahl von an seiner Oberfläche verteilten, es in seiner ganzen Wandstärke durchsetzenden Löchern 3 versehen ist. Diese sind in Fig. 1 (und auch in den Fig. 2a bis 2e) rund, könnten aber in Ausführungsvarianten eventuell z. B. schlitzförmig, oval oder kreurförmig sein.
Das Hohlelement ist wie eine Kappe auf den vorbereiteten Femurkopf la an ihm befestigt; in der Ausführungsform sind zu dieser Befestigung Stifte 4 verwendet; andere, in der Operationstechnik wohlbekannte und auch gar nicht zum eigentlichen Erfindungsinhalt gehörende Befestigungsarten sind in den Fig. 2a bis 2e veranschaulicht.
Die Löcher 3 sollten insgesmat mindestens 50% der Aussenoberfläche des Hohlelementes 2 einnehmen.
Bei einem stark beschädigten Femurkopf sollten, um eine bessere Abstützung zu erhalten, zusätzliche Spongiosaspäne eingesetzt werden. Die Funktion des Gelenks wird, bis sich der Knochen aufgebaut hat, durch die Stütz- und Fonmgebungs- prothese gewährleistet und somit auch die frühzeitige Bewegungstherapie.
Das Aufbauen des Knochens wird so verstanden, dass der Knochen durch die Löcher 3 in der Prothesenkappe 2 wächst und die Lauf- und Abstützfläche zum Teil selbst bildet. Je nach Anzahl und Grösse der Löcher könnte auch ein ganzes Überwachsen der Prothesenkappe mit Knochen erzielt werden. Um am Anfang eine bessere Lauffläche zu erhalten, könnten die Löcher mit einem abbaubaren Material, wie DexonR usw., aufgefüllt, oder die ganze Lauffläche zwischen Femurkopf und Pfanne mit einer abbaubaren Zwischenschicht versehen werden. Im Beckenteil kann eine Polyäthylenpfanne eingesetzt, oder wie bei der herkömmlichen Kopfprothese, auf ein Ersetzen des Beckenteils verzichtet werden.

PATENT CLAIMS
1. Joint prosthesis which has a hollow element with a spherical outer surface that is set up for attachment to and attachment to a natural joint head, characterized in that the hollow element has a plurality of holes distributed over its outer surface and penetrating through its entire wall thickness.
2. Joint prosthesis according to claim 1, characterized in that the holes occupy a total of at least 50% of the sen surface.
The invention relates to a joint prosthesis that has a hollow element with a spherical outer surface that is designed to be placed on and attached to a natural joint head.
So far, the defective joint parts have been removed and replaced by a non-body material, such as metal, plastic, ceramic, etc., using bone cement or screws. So a replacement prosthesis was used. It is now clear that the healing process takes quite a long time after having a replacement prosthesis.
Experts know that quite often, both with certain illnesses and with certain joint damage caused by accidents, it is sufficient to add only superficially defective joint parts to their original shape and to make it easier for the bone to build up by keeping loads away from places that have to glide on opposite articular surfaces during joint movements. A typical case is hip arthrosis.
In such cases, joint prostheses according to the preamble of claim 1 have already been placed on the natural joint head and fastened to it.
The invention was based on the object of creating a joint prosthesis of this type which can be used successfully in such cases and which enables a faster healing process. Thus, it is about the creation of an improved shell prosthesis, which considerably facilitates the subsequent assembly through natural healing processes and thus significantly promotes healing.
In order to achieve this object, the invention provides that the hollow element has a plurality of holes distributed over its outer surface and penetrating through its entire wall thickness.
Since a typical application of the invention or embodiment of the prosthesis according to the invention is such, the invention is explained with reference to the attached drawing, for example on a hip joint prosthesis. However, it should be expressly pointed out that the invention can be used with just as much success on other joint prostheses or
can be embodied. Show it
1 shows an elevation of a femur bone with an embodiment of the prosthesis according to the invention attached to its joint head, which is partially illustrated in section, and the training according to the invention, but differ in terms of the known types of attachment to the femoral head.
In FIG. 1, 1 denotes a natural femoral bone, 1 a its joint head and 2, the main part of the supporting and shaping prosthesis. This is a part-spherical hollow element made of a body-compatible material like the known joint prostheses. The spherical shape is, as in known designs, adapted to the femoral head la. What is new is that this hollow element 2 is provided with a large number of holes 3 distributed on its surface and penetrating its entire wall thickness. These are round in FIG. 1 (and also in FIGS. 2a to 2e), but could possibly be used in design variants. B. be slit-shaped, oval or circular.
The hollow element is attached to it like a cap on the prepared femoral head 1 a; in the embodiment pins 4 are used for this fastening; other types of fastening, which are well known in surgical technology and are not at all part of the subject matter of the invention, are illustrated in FIGS. 2a to 2e.
The holes 3 should take up a total of at least 50% of the outer surface of the hollow element 2.
If the femoral head is badly damaged, additional cancellous bone chips should be used to provide better support. The function of the joint is guaranteed until the bone has built up by the supporting and shaping prosthesis and thus also early movement therapy.
The building up of the bone is understood to mean that the bone grows through the holes 3 in the prosthesis cap 2 and partly forms the running and support surface itself. Depending on the number and size of the holes, a complete overgrowth of the prosthesis cap with bones could also be achieved. To get a better tread at the beginning, the holes could be filled with a degradable material such as DexonR etc., or the entire tread between the femoral head and the cup could be provided with a degradable intermediate layer. A polyethylene pan can be used in the pelvic section or, as with the conventional head prosthesis, the pelvic section can be replaced.
