The invention relates to a hip joint prosthesis according to the Preamble to the main claim DZ AS 21 34 316 describes a hip prosthesis, which has a spherical part and an acetabular part, both of which are at least in Area of their contact surfaces consist of compressed aluminum oxide, whereby the spherical part anchored in the femur with the help of a metal pin and the convex surface of the acetabular part is grooved.

In der DE-AS 22 59 313 wird eine Hüftprothese beschrieben, die einen Zapfen zur axialen --.fGstigung und mindestens einen weiteren Verankerungszapfen besitzt, dessen Achse parallel zu der der konvexen Fläche des Acetabularteils verläuft. In DE-AS 22 59 313 a hip prosthesis is described, which one Spigot for axial stabilization and at least one additional anchoring spigot whose axis is parallel to that of the convex surface of the acetabular part.

Die FR-OS 23 01 217 beschreibt eine Hüftprothese mit einem Acetabularteil, das zusätzlich zum Zapfen zur axialen Verankerung zwei seitlich parallel zum axial angeordneten Zapfen verlaufende Zapfen aufweist, die in einem Abstand von 900 zueinander in Bezug auf die Achse der konvexen Fläche des Acetabularteils angeordnet sind.FR-OS 23 01 217 describes a hip prosthesis with an acetabular part, that in addition to the pin for axial anchoring, two laterally parallel to the axial arranged pin has extending pins that are at a distance of 900 from each other are arranged with respect to the axis of the convex surface of the acetabular part.

Durch die im Hauptanspruch -definierte Erfindung wird eine Hüftgelenkprothese geschaffen, deren Acetabularteil gegenüber Rotationskräften oder Kippbeanspruchungen noch sicherer als beim Stand der Technik in seiner Aufnahmeöffnung verankert bleibt. The invention defined in the main claim provides a hip joint prosthesis created, the acetabular part against rotational forces or tilting stresses remains anchored in its receiving opening even more securely than in the prior art.

Bei der erfindungsgemäßen Prothese, bei der die zur Verankerung im Knochen dienenden Zapfen gleichmäßiger über die konvexe Oberfläche des Acetabularteils verteilt sind als bei bekannten Prothesen, ist eine rasche Befestigung des Acetabularteils im Hüftknochen gewährleistet, bevor noch das nachwachsende Knochengewebe die Rillen voll ausfüllt. In the prosthesis according to the invention, in which the anchoring in the Bone serving cones more evenly over the convex surface of the acetabular part are distributed than with known prostheses, is a quick attachment of the acetabular part Guaranteed in the hip bone before the regrowing bone tissue forms the grooves fully filled.

Bevorzugte Ausführungsformen der Erfindung werden in den Unteransprüchen angegeben. Preferred embodiments of the invention are set out in the subclaims specified.

Nachfolgende werden unter Bezugnahme auf die drei beiliegenden Figuren Ausführungsbeispiele für das Acetabularteil der erfindungsgemäßen Hüftprothese beschrieben. The following are made with reference to the three accompanying figures Described embodiments for the acetabular part of the hip prosthesis according to the invention.

-Fig. 1 zeigt etwa zur Hälfte in Seitenansicht und zur anderen Hälfte im axialen Schnitt (Achse OA Fig. 2) ein Acetabularteil mit drei peripher angeordneten Verankerungazapfen. -Fig. 1 shows about half in side view and the other half in axial section (axis OA FIG. 2) an acetabular part with three peripherally arranged Anchoring spigot.

Fig. 2 zeigt dasselbe Acetabularteil von oben. Fig. 2 shows the same acetabular part from above.

Fig. 3 zeigt in Seitenansicht einen axial verlaufenden Verankerungszapfen, der zusätzlich zu den peripheren Zapfen vorgesehen wird. Fig. 3 shows a side view of an axially extending anchoring pin, which is provided in addition to the peripheral pin.

Das in den Figuren 1 und 2 dargestellte, aus gesintertem Aluminiumoxyd bestehende Acetabularteil umfaßt einen eingeschliffenen konkaven Teil 1, der die Gelenkpfanne für den ebenfalls aus eingeschliffenem Aluminiumoxyd bestehenden sphärischen Oberschenkelhalsknochenkopf aufnehmen soll. Die konvexe Fläche 2 des Acetabularteils ist, wie in der DE-OS 25 23 267 beschrieben, mit drei Arten von koaxialen Rillen versehen, von denen Rillen 3 zwischen koaxialen Zylindern, Rillen 4 in einem Zwischenbereich zwischen Kegeln, deren Spitzen auf der Achse des Acetabularteils liegen, und Rillen 5 im äquatorialen Bereich zwischen senkrecht zur Achse verlaufenden Ebenen eingeschnitten sand, Die Nuten6 breite dieser Rillen beträgt 1 bis 2 mmo und im Verhältnis zu ihrem idealen Profil sind sie zur leichteren Herstellung nach außen leicht erweitert0 Das Acetabularteil ist mit drei peripher angeordneten Verankerungszapfen versehen0 von denen zweite die Zapfen 6 und 7, in Fig. lo und der dritte Zapfen 11 in Fig0 2 sichtbar sind0 Diese peripher angeordneten Zapfen weisen einen Winkelabstand von 85° zueinander auf Weiterhin besitzt das Acetabularteil Rillen 8, 13 und 14 in den Halbierungsebenen der durch die Achsen der peripher angeordneten Zapfen verlaufenden Durchmesserebenen. Der mittlere der drei peripher angeordneten Zapfen, der@ Zapfen 6, weist Rillen auf, die ech nicht über seinen gesamten Umfang erstrecken. Der Zapfen endet in einer ebenen Stirnfläche 10, die über eine Fase von 450 mit den Zylinderseitenflächen des Zapfens in Verbindung steht0 Die Achse dieses Zapfens schneidet die Kugel fläche der konvexen Seite des Teils 1 beispselso weise in Höhe des 45. Breitengrades. The one shown in Figures 1 and 2, made of sintered aluminum oxide existing acetabular part comprises a ground concave part 1, which the Joint socket for the spherical one, which is also made of ground aluminum oxide To accommodate the femoral neck bone head. The convex surface 2 of the acetabular part is, as described in DE-OS 25 23 267, with three types of coaxial grooves provided, of which grooves 3 between coaxial cylinders, grooves 4 in an intermediate area between cones, the tips of which lie on the axis of the acetabular part, and grooves 5 in the equatorial area between perpendicular running to the axis Plains incised sand, the grooves6 width of these grooves is 1 to 2 mmo and in relation to their ideal profile, they are designed for ease of manufacture slightly enlarged on the outside0 The acetabular part has three peripheral anchoring pegs Provided0 of the second the pins 6 and 7, in Fig. Lo and the third pin 11 are visible in Fig0 2. These peripherally arranged pins are angularly spaced From 85 ° to each other, the acetabular part also has grooves 8, 13 and 14 in the bisection planes of the pins extending through the axes of the peripherally arranged pins Diameter planes. The middle of the three peripherally arranged pegs, the @ peg 6, has grooves which ech do not extend over its entire circumference. The cone ends in a flat end face 10, which has a bevel of 450 with the cylinder side surfaces of the pin is in connection0 The axis of this pin intersects the spherical surface the convex side of part 1, for example, at the 45th parallel.

Der in Fig, 3 gezeigte zusätzlicha axiale Verankerungszapfen besitzt eine allgemeine Kegelstumpfform. Sein Durchmesser beträgt beispielsweise 8 mm an seiner Basis 15 und 5 mm an seinem Ende 16. Er ist mit Umfangsrillen# 17 versehen0 die sich über seinen gesamten Umfang erstrecken. Seine Höhe über der Äquatorialebene des Acetabularteils reicht nicht über die der peripher angeordneten Verankerungs-zapfen hinaus0 Die Rillen in einem peripher angeordneten Veranke rungszapfen nehmen nur einen Bruchteil des Umfangs ein, wobei dieser Bruchteil von oben nach unten abnimmt, um die mechanische Festigkeit gegenüber senkrecht zur Achse einwirkenden Biegebeanspruchungen zu erhöhen. So nimmt die am weitesten oben liegende Rille 19 5/6 des Umfangs ein, während die darunterliegenden Rillen 20, 21 und 22 jeweils 2/3, 1/2 und 1/3 des Umfangs einnehmen. Die Rillen sind dabei auf der Außenseite angebracht. The additional axial anchoring pin shown in FIG. 3 has a general truncated cone shape. Its diameter is, for example, 8 mm its base 15 and 5 mm at its end 16. It is provided with circumferential grooves # 170 which extend over its entire circumference. Its height above the equatorial plane of the acetabular part does not extend beyond the anchoring pegs arranged on the periphery Furthermore, the grooves in a peripheral anchoring pin only take a fraction of the circumference, where this fraction from above decreasing downwards to the mechanical strength compared to perpendicular to the axis to increase acting bending loads. So take the one furthest on top Groove 19 5/6 of the circumference, while the underlying grooves 20, 21 and 22 occupy 2/3, 1/2 and 1/3 of the circumference respectively. The grooves are on the outside appropriate.

Es ist vorteilhaft, scharfe Winkel in den vertieft liegenden Bereichen des Acetabularteils, vor allem am Boden der Rillen auf der konvexen Seite des Acetabularteils und auf den Verankerungszapfen zu vermeiden, indem diese unter Wahrung eines Abrundungsradius von mindestens 0,2 mm abgerundet werden. It is beneficial to have sharp angles in the recessed areas of the acetabular part, especially at the bottom of the grooves on the convex side of the acetabular part and avoid on the anchoring pegs by maintaining a radius of curvature rounded off by at least 0.2 mm.
