Abstract

A hip joint has a ball and socket joint with a ball cap implant (1) whose profile conforms to that of the natural original upon which it replaces. The inner face of the hollow cap incorporates packing material that fills the voids between the damaged original bone and the cap inner face.

Description

Die vorliegende Erfindung betrifft ein Gelenkkopf-Kappenimplantat für ein künstliches Hüftgelenk, das aus einer der äußeren Form der natürlichen Gelenkkugel nachgebildeten Kappe besteht, die auf einen (teil)präparierten natürlichen Restgelenkkopf setzbar ist.The The present invention relates to a condyle cap implant for an artificial one Hip joint, that from one of the outer form the natural one Joint ball simulated cap that prepared on a (part) natural Residual joint head is settable.

Ein derartiges Implantat lässt sich aus dem sogenannten Set zur Erstellung eines Armierungsimplantates gemäß der DE 102 18 801 B3 erstellen.Such an implant can be from the so-called set for creating a Armierungsimplantates according to the DE 102 18 801 B3 create.

In jüngster Zeit kommen verstärkt sogenannte Kappenimplantate zur Anwendung, welche über den präparierten natürlichen Restgelenkkopf gesetzt werden und in dieser Lage dann fixiert werden. Voraussetzung für eine stabile Sekundärfixation ist stabiles Knochenmaterial des Restknochens. So wird in der schon erwähnten Druckschrift vorgeschlagen, an die Gelenkkopfkappe einen Zapfen anzukoppeln, der in eine entsprechende Ausfräsung im Schenkelhals gesetzt wird. Dieser Zapfen weist eine Oberfläche auf, welche mit einer dreidimensionalen offenmaschigen Raumnetzstruktur versehen ist, in welche und durch welche hindurch Knochentrabekel des umliegenden Knochenmaterials wachsen und für die stabile Sekundärfixation sorgen.In recently, Time is increasing so-called cap implants for use, which over the groomed natural Residual joint head are set and then fixed in this position. requirement for a stable secondary fixation is stable bone material of the residual bone. So in the already mentioned Reference proposed, to the condyle cap a pin coupled, which set in a corresponding cutout in the femoral neck becomes. This pin has a surface which with a three-dimensional open-meshed spatial network structure is provided, in which and by which through bone trabeculae of the surrounding bone material grow and for the stable secondary fixation to care.

Es gibt jedoch Indikationen, bei denen man noch davon absehen kann, den Schenkelhals auszufräsen, um so Platz für den Zapfen zu schaffen. Angeführt wird hier die sogenannte Perthes-Calvé-Legg-Krankheit, die ein- oder beidseitig im Bereich der Femurkopfepiphyse aseptische Knochennekrosen hervorruft. Vor allem bei Jungen vom 4. bis 12. Lebensjahr tritt diese Krankheit auf (Pschyrembel, Klinisches Wörterbuch, 259. Auflage, 2002, Seite 1285). Eine Ausheilung ohne Deformierung ist zwar möglich, jedoch bleibt eine eventuelle Walzen- oder Pilzform des Schenkelkopfes mit Abplattung der Hüftgelenkpfanne, seltener Coxa Plana und Arthrosis deformans zurück.It However, there are indications where you can still refrain from to rake the femoral neck, so much room for to create the pin. led Here, the so-called Perthes-Calvé-Legg disease, which or bilateral aseptic bone necrosis in the area of the femoral epiphysis causes. Especially in boys from 4 to 12 years occurs this disease (Pschyrembel, Clinical Dictionary, 259th Edition, 2002, Page 1285). An annealing without deformation is possible, however remains a possible roll or mushroom shape of the femoral head with flattening of the acetabular cup, rarer Coxa plana and Arthrosis deformans back.

Eine weitere Indikation ist beispielsweise eine Zyste im Hüftgelenkskopf, die zu Oberflächendefekten des Gelenkkopfes führt.A further indication is, for example, a cyst in the hip joint head, which leads to surface defects of the condyle leads.

Ganz generell kann eine Nekrose des Gelenkkopfes zu oberflächenhaften Defekten führen, die es aber immer noch nicht rechtfertigen, den Gelenkkopf vollständig zu resezieren und den Patienten mit einer Kurzstielendoprothese ( EP 0 878 176 B1 ) versorgen.In general, necrosis of the condyle can lead to surface defects, but still can not justify resection of the condyle completely and provide the patient with a short stem endoprosthesis ( EP 0 878 176 B1 ) supply.

Problematisch hierbei freilich ist, dass an den Stellen der Oberflächendefekte des Kopfes das Innere des Kappenimplantates nicht oder nicht vollständig zum Anliegen an den Knochen kommt. Dies bedeutet, dass die auftretenden Kräfte nicht gleichmäßig über die gesamte Oberfläche des Gelenkkopfes in den Femur eingeleitet werden. Daher hat man bislang versucht, die Oberflächendefekte entweder durch Zement, sofern eine zementierbare Kappe implantiert wird, oder aber durch Knochenmaterial des Patienten zu heilen. So ist aus der DE 20 003 360 U1 ein Hüftgelenkkopf-Kappenimplantat bekannt, das aus einer der äußeren Form der natürlichen Gelenkkugeln nachgebildeten Kappe besteht, die auf einen natürlichen Restgelenkkopf setzbar ist. Der Hüftgelenkkopf behält weitgehend seine natürliche Gestalt und Größe. Sklerotische oder nekrotische Regionen werden vor Aufsetzen der Kappe entfernt. Nach Versorgung der Mikroblutungen wird entweder die nunmehr gegenüber der ursprünglichen Krümmung etwas abgeflachte Spongiosa-Oberfläche so belassen oder das resektierte Volumen wird mit biokompatiblem Material teilweise wieder aufgefüllt. Die Langzeitstabilität dieser Maßnahmen ist meist nicht ganz befriedigend.Of course, the problem here is that at the sites of the surface defects of the head, the interior of the cap implant does not or does not completely come into contact with the bone. This means that the occurring forces are not introduced uniformly over the entire surface of the condyle in the femur. Therefore, attempts have hitherto been made to cure the surface defects either by cement, if a cementable cap is implanted, or by bone material of the patient. So is out of the DE 20 003 360 U1 a hip joint cap implant is known, which consists of one of the outer shape of the natural joint balls modeled cap, which is settable on a natural residual joint head. The femoral head largely retains its natural shape and size. Sclerotic or necrotic regions are removed before the cap is put on. After supplying the microbleeds, either the spongiosa surface, which is now somewhat flattened in relation to the original curvature, is left or the resected volume is partially refilled with biocompatible material. The long-term stability of these measures is usually not entirely satisfactory.

Vor diesem Hintergrund ist es die Aufgabe der vorliegenden Erfindung, hier Abhilfe zu schaffen, d. h. also ein Gelenkkopf-Kappenimplantat vorzuschlagen, welches über eine hervorragende Langzeitstabilität verfügt und dessen Inneres praktisch vollständig mit dem verbliebenen natürlichen Gelenkkopf im unmittelbaren Kontakt steht.In front In this context, it is the object of the present invention Remedy here, d. H. So a condyle cap implant to suggest which over has excellent long-term stability and its interior is virtually complete with the remaining natural Rod end is in direct contact.

Gelöst wird diese Aufgabe durch das Gelenkkopf-Kappenimplantat mit den weiteren Merkmalen gemäß dem Anspruch 1.Is solved this task by the condyle cap implant with the other Features according to the claim 1.

Weitere vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Further advantageous developments emerge from the subclaims.

Demgemäß sind im Inneren der Kappe Materialanhäufungen vorgesehen zur Füllung von Oberflächendefekten in der natürlichen Gelenkkugel, die einstückig mit dem Material der Gelenkkappe ausgebildet sind, wobei das Kappeninnere zumindest teilweise mit einer offenmaschigen dreidimensionalen Raumnetzstruktur versehen ist. Die Materialanhäufungen füllen die Oberflächendefekte des natürlichen Gelenkkopfes aus, so dass es de facto zu einem großflächigen Formenschluss zwischen dem Inneren der Kappe und der natürlichen Gelenkkugel kommt. Eine gleichmäßigere Krafteinleitung in den Femur ist hiervon die Folge. Das Material wird typischerweise körperverträgliches Metall sein. Die Materialanhäufungen sind dann im Feingussverfahren direkt mit der Kappe erzeugt worden. In die Raumnetzstruktur und durch sie hindurch wachsen Knochentrabekel des umliegenden Knochenmaterials und können für eine stabile Sekundärfixation sorgen.Accordingly, in Inside of the cap material pilings intended for filling of surface defects in the natural Joint ball, the one-piece formed with the material of the joint cap, wherein the cap interior at least partially with an open-mesh three-dimensional spatial network structure is provided. The material accumulations to fill the surface defects of the natural condyle out, making it de facto a large-scale mold between the inside of the cap and the natural joint ball comes. A more uniform application of force This is the result in the femur. The material typically becomes biocompatible Be metal. The material accumulations were then produced by precision casting directly with the cap. In the spatial network structure and through them grow bone trabeculae of the surrounding bone material and can for a stable secondary fixation to care.

Das Kappenimplantat kann patientenindividuell nach Vermessung der Oberflächendefekte durch CT oder Röntgen hergestellt werden. Aus Kostengründen bevorzugt wird aber ein standardisiertes Implantat mit zumindest einer standardisierten Materialanhäufung. Dies führt dazu, dass der Operateur während der Operation Anpassungen an dem natürlichen Gelenkkopf vornehmen muss, damit der erwünschte Formenschluss eintreten kann. Genauer bedeutet dies, dass der Operateur gegebenenfalls am natürlichen Restgelenkkopf Materialabtragungen vornehmen muss, in welche dann die standardisierten Materialanhäufungen im Inneren der Kappe zum Liegen kommen.The Cap implant can be patient-specific after measuring the surface defects by CT or X-ray getting produced. For cost reasons but preferred is a standardized implant with at least a standardized material accumulation. This leads to, that the surgeon during the surgery make adjustments to the natural condyle must, so that the desired Mold can occur. More precisely, this means that the surgeon optionally on natural Residual joint head material removal must make, in which then the standardized material accumulations to come to rest inside the cap.

Die Materialanhäufungen können bis zu einem Drittel des Durchmessers der Kappe an ihrer Basiskante in das Innere der Kappe ragen. Darüber hinausgehende Dimensionen könnten kritisch sein, da die dann zu füllenden Oberflächendefekte so tief sind, dass die Stabilität der natürlichen Gelenkkugel als Ganzes in Frage stehen könnte.The material accumulations can up to one third of the diameter of the cap at its base edge to protrude into the interior of the cap. Further dimensions could be critical, because then to be filled surface defects so deep are that stability the natural one Joint ball as a whole could be in question.

Auch die Materialanhäufungen können bevorzugt zumindest teilweise mit einer offenmaschigen dreidimensionalen Raumnetzstruktur versehen sein, und zwar aus demselben erwähnten Grunde.Also the material accumulations can preferably at least partially with an open-meshed three-dimensional Be provided spatial network structure, and for the same reason.

Die Erfindung wird anhand der einzigen Zeichnungsfigur beispielhaft näher erläutert.The Invention will be exemplified with reference to the single drawing figure explained in more detail.

Die einzige Zeichnungsfigur zeigt ein Gelenkkopf-Kappenimplantat 1 im Querschnitt. Deutlich erkennbar ist die äußere Form, die der Form der natürlichen Gelenkkugel nachgebildet ist.The single drawing figure shows a condyle cap implant 1 in cross section. Clearly recognizable is the external shape, which is modeled on the shape of the natural joint ball.

Das Kappeninnere weist drei Abschnitte auf, und zwar ausgehend von der Basiskante 3 einen steileren Abschnitt, dem sich ein flacherer Abschnitt anschließt, der schließlich in den waagerechten Kappenboden übergeht.The cap interior has three sections, starting from the base edge 3 a steeper section, followed by a flatter section that eventually merges into the horizontal cap floor.

Links im Querschnitt angedeutet ist die Materialanhäufung 2, die als Defektfüller für Oberflächendefekte in der natürlichen Gelenkkugel dient.Indicated on the left in the cross section is the accumulation of material 2 which acts as a defect filler for surface defects in the natural joint ball.

Die Materialanhäufung 2 ist schräg zulaufend ausgebildet. Das Maß a beträgt beispielsweise (im hier dargestellten vergrößerten Fall) in der Realität 2,5 mm, das Maß b beispielsweise 5 mm. Maximal bis zu einem Drittel des Durchmessers an der Basiskante 3 sollten die Materialanhäufungen 2 einnehmen.The material accumulation 2 is formed tapered. The dimension a is for example (in the enlarged case illustrated here) in reality 2.5 mm, the dimension b, for example, 5 mm. Up to one third of the diameter at the base edge 3 should the material accumulations 2 taking.

Sämtliche Abschnitte des Kappeninneren sind mit einer offenmaschigen dreidimensionalen Raumnetzstruktur 4 versehen. Das Gleiche trifft zu für die Materialanhäufung 2, bei der die Raumnetzstruktur 5 zur stabilen Sekundärfixation beiträgt.All sections of the cap interior are with an open-mesh three-dimensional spatial network structure 4 Mistake. The same applies to the accumulation of material 2 in which the spatial network structure 5 contributes to stable secondary fixation.
