Abstract

The artificial joint is for permanent insertion in the body, joining two bones together. Its parts (17) extending inside the bone substance (7, 15) are enclosed in implantation material harmless to the latter, typically aluminium oxide. There can be an external screw thread (19) forming in the enclosing material, which can also have radial openings to accommodate anchoring pins or screws. There can also be an internal screw thread in the enclosing material, by which it is secured to the joint component.

Description

Gelenkprothese Joint prosthesis

Die Erfindung betrifft eine dauerhaft im Körper verbleibende und in den Knochen eines Gelenks verankerbare Gekenkprothese.The invention relates to a permanently remaining in the body and in Joint prosthesis that can be anchored in the bone of a joint.

Durch Abnutzung (Arthrose) oder andere Krankheiten verbrauchte bzw. mit irreperablen Schäden behaftete Gelenke können durch künstliche Bewegungsteile ersetzt werden. Die ineinandergreifenden und sich gegeneinander bewegenden Gelenkenden werden durch ähnlich geformte Prothesenteile aus körperfremdem Material ersetzt. Die künstlichen Gelenkteile werden dabei durch vollständige oder teilweise Einbettung in die Knochenmasse verankert.Consumed or damaged by wear and tear (osteoarthritis) or other diseases Joints afflicted with irreparable damage can be caused by artificial moving parts be replaced. The interlocking and mutually moving joint ends are replaced by similarly shaped prosthesis parts made from foreign material. The artificial joint parts are thereby by complete or partial embedding anchored in the bone mass.

Ein Hauptproblem bezüglich der Haltbarkeit einer Prothese ist die dauerhafte, stabile Verankerung der Prothesenteile im Knochen. Nur durch eine feste Verbindung zwischen den Prothesenteilen und den Knochen kann ein zuverlässig und auf Dauer belastbares Kunstgelenk entstehen.A major problem with the durability of a prosthesis is that permanent, stable anchoring of the prosthesis parts in the bone. Just by a solid Connection between the prosthesis parts and the bones can be a reliable and permanent resilient artificial joints are created.

Seit fast zwei Jahrzehnten ist es daher bekannt, die Prothesenteile mit einem Zement in den Knochen einzuzementieren. Als Zement dient hierbei ein selbst-polymerisierendes Methylmethacrylat, ein Methylester der Methachrylsäure. Der Knochenzement dringt beim Einpressen in die Lücken des spongiösen Knochens und bildet somit eine innige Verzahnung und damit einen belastbaren Formschluß. Diese Befestigungsart hat den Nachteil, daß es zum Teil schon nach wenigen Jahren zu einer Lockerung zwischen dem Knochen und dem Zement kommt.It has therefore been known for almost two decades, the prosthetic parts cement it into the bone with a cement. A self-polymerizing cement is used here Methyl methacrylate, a methyl ester of methachrylic acid. The bone cement penetrates when pressed into the gaps of the cancellous bone and thus forms one intimate interlocking and thus a resilient form fit. This type of attachment has the disadvantage that after a few years there is a loosening between the bone and the cement.

Die Ursachen liegen in einer thermischen Schädigung des anliegenden Gewebes durch die Polymerisationswärme, die bis zu 1000 C betragen kann. Als weitere Ursache für die Lockerung der Prothesenteile ist eine Infektion im Bereich des Gelenkes bekannt. Eine Lockerung vonfrothesenteilen führt zu einer schmerzhaften Funktionsstörung am Gelenk.The causes lie in thermal damage to the adjacent Fabric through the heat of polymerization, which can be up to 1000 C. As another The cause of the loosening of the prosthesis parts is an infection in the area of the joint known. A loosening of the prosthesis parts leads to a painful dysfunction at the joint.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Gelenkprothese der eingangs genannten Art zu schaffen, deren Teile dauerhafter als bisher im Knochen verankert werden können. Die erfindungsgemäße Lösung ist dadurch gekennzeichnet, daß die in die Knochensubstanz reichenden Teile der Prothese von einem knochenfreundlichen Implantatmaterial umhüllt sind. In weiterer Ausbildung gemäß der Erfindung wird vorgeschlagen, als Implantatmaterial Aluminiumoxyd (A203), welches an sich in der Fachwelt bekannt ist und sich den bisherigen Materialien in Körperverträglichkeit, Abriebfestigkeit und Korrosionswiderstand weit überlegen gezeigt hat.The invention is therefore based on the object of a joint prosthesis of the type mentioned to create, the parts of which are more permanent than before in the bone can be anchored. The solution according to the invention is characterized in that that the parts of the prosthesis reaching into the bone substance are made from a bone-friendly one Implant material are encased. In a further training according to the invention proposed as the implant material aluminum oxide (A203), which in itself in the Is known to the professional world and the previous materials in body compatibility, Has shown to be far superior to abrasion resistance and corrosion resistance.

Die Umhüllungen können als separate Hüllteile mit einem Außengewinde versehen sein und in entsprechend mit Innengewinden vorbereitete Knochen eingesetzt werden. Neben dem Einschrauben eines Hüllteils in den Knochen ist eine Verankerung mit der Knochenmasse durch stiftförmige Befestigungsmittel bzw. Schrauben möglich, die durch radiale Öffnungen des Hüllteils hindurch in die Knochenmasse greifen. Eine Verbindung zwischen den Hüllteilen und den darin einsetzbaren Prothesenteilen ist gleichfalls durch eine Verschraubung möglich. Zu diesem Zweck sind die Hüllteile mit einem Innengewinde und die darin eingeführten Prothesenteile mit einem Außengewinde versehen. Ferner besteht die Möglichkeit, die Verbindung durch den vorgenannten Knochenzement herzustellen. Zu diesem Zweck können die ineinandergreifenden Teile mit einigen die Haftfähigkeit erhöhenden Vorsprüngen bzw. Vertiefungen versehen werden. Bei der Verwendung eines pfannenförmigen Hüllteils, welches mit Hilfe von Schrauben im Beckenknochen verankert ist, besteht der Vorteil, dieses unmittelbar als Pfanne ohne einen zusätzlichen Einsatz zu verwenden. Besonders vorteilhaft ist die Ausbildung eines den Prothesenteil aufnehmenden und in den Oberschenkelknochen einsetzbaren Hüllteis in Form einer Hülse mit einem vieleckigen, beispielsweise achteckigen Innenquerschnitt, um dadurch einen Formschluß mit dem entsprechend ausgebildeten Prothesenstiel zu erhalten.The covers can be used as separate cover parts with an external thread be provided and inserted into bones prepared accordingly with internal threads will. In addition to screwing a shell part into the bone, there is an anchorage possible with the bone mass using pin-shaped fasteners or screws, which reach through radial openings in the shell part into the bone mass. A connection between the shell parts and the prosthesis parts that can be inserted therein is also possible through a screw connection. To this end are the shell parts with an internal thread and the prosthesis parts inserted therein provided with an external thread. There is also the option of connecting to produce by the aforementioned bone cement. To this end, the interlocking Provide parts with some protrusions or depressions that increase the adhesion will. When using a pan-shaped shell part, which with the help of Screws anchored in the pelvic bone, there is the advantage of this immediately to use as a pan without an additional insert. Is particularly advantageous the formation of a prosthesis part receiving and in the thigh bone usable shell ice in the form of a sleeve with a polygonal, for example octagonal inner cross-section to thereby form a positive fit with the appropriately designed To obtain prosthetic stem.

Durch den Formschluß ist der Prothesenstiel gegen Verdrehung um seine Längsachse gesichert. Aufgrund der natürlichen Belastungsverhältnisse erscheint es nicht notwendig, den Prothesenstiel eines Hüftgelenks in Längsrichtung festzulegen, jedoch kann auch dies durch eine konische Ausbildung der Hülse und des Prothesenstiels in einfacher Weise erreicht werden.Due to the form fit, the prosthesis stem is against twisting around its Longitudinal axis secured. Due to the natural load conditions appears it is not necessary to fix the prosthetic stem of a hip joint in the longitudinal direction, however, this can also be achieved by conical design of the sleeve and the prosthesis stem can be achieved in a simple manner.

Die Verankerung einer Hülle aus biokeramischem Material gewährleistet eine wesentlich dauerhaftere Verankerung des gesamten Prothesenteils. Es hat sich gezeigt, daß sich die Gewindetäler mit immer dichterem Knochen füllen. Ferner wurden keine Resorptionsprozesse beobachtet, die letztlich zu einer Lockerung des Implantats führen.The anchoring of a cover made of bioceramic material is guaranteed a much more permanent anchoring of the entire prosthesis part. It has shown that the thread valleys fill with increasingly dense bone. Furthermore were no resorption processes were observed, which ultimately led to loosening of the implant to lead.

Dagegen ist eine Zementverbindung oder eine Formschlußverbindung der aus lebloser Materie bestehenden Teile untereinander in vollauf zufriedenstellendem Maße möglich. Damit ist die wichtigste Voraussetzung für eine dauerhaftere Verankerung der Prothesenteile im Knochen erreicht. Außerdem wird insbesondere bei den in den Oberschenkelknochen einsetzbaren Teilen einer Hüftgelenkprothese durch das Außengewinde und das beobachtete Einwachsen der Knochensubstanz in das biokeramische Implantatmaterial ein wesentlich besserer Kraftfluß zwischen deryProthesenteilen und dem Knochenmaterial erreicht. Dadurch wird ferner der Prothesenhals weniger hoch belastet. Infolgedessen ist die Gefahr eines Ermüdungsbruches in diesem Bereich entscheidend herabgesetzt.In contrast, a cement connection or a form-fitting connection is the parts consisting of inanimate matter with each other in fully satisfactory Dimensions possible. This is the most important requirement for a more permanent anchoring of the prosthesis parts in the bone. In addition, especially in the Femur parts of a hip joint prosthesis insertable through the external thread and the observed ingrowth of the bone substance into the bioceramic implant material a much better flow of forces between the prosthesis parts and the bone material achieved. As a result, the neck of the prosthesis is also less stressed. Consequently the risk of a fatigue fracture in this area is significantly reduced.
