Abstract
Description
Die vorliegende Erfindung betrifft eine Sprunggelenkendoprothese. Eine gattungsgemäße Sprunggelenkendoprothese weist einen in der Tibia implantierbaren Tibiateil, ein in den Talus implantierbaren Talusteil sowie ein mit dem Tibiateil lösbar verbindbares Plateauteil mit zwei taluswärts zugewandten, von einem Mittelsteg getrennten Ausmuldungen, die als Gleitflächen für entsprechend konvex ausgebildete, auf die tibiawärts zugewandte Oberfläche des Talusteils ausgeformte Gleitkufen dienen, welche von einer dem Mittelsteg des Plateauteils entsprechenden Rinne getrennt sind.The present invention relates to an ankle endoprosthesis. A generic ankle prosthesis has one in the tibia implantable tibia part, a talus part implantable in the talus and a with plateau part releasably connectable to the tibia part with two talus-facing, troughs separated by a central web, which serve as sliding surfaces for correspondingly convex surface facing the tibia Talus section shaped skids, which from a the central web of the Plateau part corresponding gutter are separated.
Eine derartige Sprunggelenkendoprothese ist bekannt aus der DE 39 04 004 C2.Such an ankle endoprosthesis is known from DE 39 04 004 C2.
Diese Sprunggelenkendoprothese hat sich in der Praxis sehr bewährt. Als problematisch hat sich die Starrheit des Gelenkes herausgestellt in dem Moment, wenn durch beispielsweise eine Fehlimplantation des Tibiateils das Gesamtgelenk ständig unter Spannung steht. Hierfür ist in dem bekannten Gelenk keine Kompensationsmöglichkeit vorgesehen.This ankle endoprosthesis has proven itself very well in practice. As the rigidity of the joint turned out to be problematic at the moment if, for example, incorrect implantation of the tibia part of the entire joint is constantly under tension. There is none for this in the known joint Possibility of compensation provided.
Vor diesem Hintergrund ist es nun die Aufgabe der vorliegenden Erfindung, die gattungsgemäße Sprunggelenkendoprothese so weiterzubilden, daß eine Kompensationsmöglichkeit für Fehlimplantationen des Tibiateils geschaffen wird.Against this background, it is the object of the present invention that Generic ankle prosthesis so that a Compensation option for incorrect implantation of the tibia part is created.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1 bei einer gattungsgemäßen Sprunggelenksendoprothese. This problem is solved by the characterizing features of the claim 1 for a generic ankle endoprosthesis.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous further developments result from the subclaims.
Demnach ist erfindungsgemäß vorgesehen, daß das Plateauteil mit dem Tibiateil so verbindbar ist, daß es - ausgehend von der Nulllage - in einem Winkel im Bereich von -5° bis +5° anschlagsbegrenzt um die Hochachse eines in das Tibiateil eingelassenen Zapfens verschwenkbar gelagert ist.Accordingly, the invention provides that the plateau part with the tibia part is so connectable that - starting from the zero position - at an angle in Range from -5 ° to + 5 ° limited by the vertical axis of one in the Tibial part recessed pin is pivotally mounted.
Diese Verschwenk- oder Rotationsmöglichkeit kompensiert Fehlimplantationen, das heißt, Implantationen des Tibiateils mit nicht ganz korrekter Orientierung im großen Umfang. Die Fehlimplantationen kommen dadurch zustande, daß bei den während der Operationen ohnehin eingeschränkten Verhältnissen die Größenverhältnisse relativ klein sind und Abweichungen von nur wenigen Graden von der Idealachse der Implantation Auswirkungen auf das Gesamtgelenk verursachen. Die Rotationsmöglichkeit bei dem erfindungsgemäßen Sprunggelenk gestattet nun eine Ausgleichsbewegung des Plateauteils an dem Tibiateil und hilft so, gelenkinterne Spannungen zu vermeiden bzw. abzubauen. Kommt es aufgrund einer Fehlimplantation zu Spannungen in den Bändern, so sucht sich das Plateauteil selbsttätig die Lage geringster Spannung, das heißt, das Gelenk stellt sich selbsttätig auf einen möglichst spannungsfreien Zustand ein. Der Patient bemerkt dies durch einen beschwerdefreien physiologischen Bewegungsablauf einerseits und einer weitgehenden Schmerzfreiheit des Bandapparates andererseits.This pivoting or rotating possibility compensates for incorrect implantations, that is, implantation of the tibia part with an incorrect orientation in the large scale. The incorrect implantations are caused by the fact that the during the operations anyway restricted conditions Size ratios are relatively small and deviations of just a few degrees from the ideal axis of implantation effects on the entire joint cause. The possibility of rotation in the ankle according to the invention now allows a compensatory movement of the plateau part on the tibia part and helps to avoid or reduce internal joint tensions. It comes because of incorrect implantation to tension in the ligaments, that's what it looks for Plateau part automatically the position of the lowest tension, that is, the joint provides automatically adjust to a state that is as tension-free as possible. The patient notices this through a symptom-free physiological movement on the one hand and extensive freedom from pain in the ligamentous apparatus on the other hand.
Konstruktiv weist das Tibiateil besonders bevorzugt talusseitig eine kastenförmige Begrenzungskante auf, die den Anschlag für die Verschwenkbewegung des Plateauteils bildet. Dabei weist das Plateauteil einen Schwenksockel auf, dem sich der Abschnitt mit den Ausmuldungen anschließt, wobei die Höhe des Schwenksockels wenigstens gleich der Höhe der Begrenzungskante ist und der Zapfen des Tibiateils in eine entsprechende Ausnehmung im Schwenksockel greift. The tibia part has a box-shaped design, particularly preferably on the talus side Boundary edge on the stop for the pivoting movement of the Plateau part forms. The plateau part has a swivel base, which is the section with the excavations follows, the amount of the Swivel base is at least equal to the height of the boundary edge and the Pin the tibia part into a corresponding recess in the swivel base attacks.
Die kastenförmige Begrenzungskante kann gemäß einer bevorzugten Ausführungsform geschlossen, das heißt, voll umlaufend sein. In diese dadurch gebildeten Einfassung wird dann das Plateauteil gesetzt. Der angegebene Verschwenkbereich wird erzielt durch eine entsprechende Formgebung des Schwenksockels, welcher bei einer Auslenkung von -5° bzw. +5° an die Begrenzungskante stößt, so daß die für weitere Verschwenkbewegung unterbunden wird.The box-shaped boundary edge can be according to a preferred one Embodiment closed, that is, be all-round. In this by doing so formed enclosure is then placed on the plateau part. The specified Swiveling range is achieved by appropriate shaping of the Swivel base, which with a deflection of -5 ° or + 5 ° to the Boundary edge abuts, so that for further pivoting movement is prevented.
Gemäß einer zweiten bevorzugten Ausführungsform kann die kastenförmige Begrenzungskante an einer Seite offen sein, so daß der Schwenksockel in den offenen Begrenzungsbereich hinein geschoben werden kann. Hierzu ist in dem Schwenksockel ein Langloch eingelassen, in welchem der Zapfen des Tibiateils während des Einsatzes des Plateauteils in das Tibiateil führbar ist und dessen Ende ein Anschlag für den Zapfen in der Endstellung des Plateauteils sowie das Zentrum der Verschwenkbewegung bildet. Das Plateauteil wird mit seinem Schwenksockel also mit dem eingelassenen Langloch an den Zapfen gesetzt und in den offenen Umgrenzungsbereich hineingeschoben, so lange, bis der Zapfen am Ende des Langloches anschlägt. In dieser Lage kann das Plateauteil mit dem Zapfen als Schwenkachse in gewünschter Weise verschwenken. Der Vorteil dieser Ausführungsform ist ein einfacheres Austauschen eines etwaig verschleißten Plateauteils.According to a second preferred embodiment, the box-shaped Boundary edge open on one side, so that the swivel base in the open boundary area can be pushed into it. This is in the Swivel base recessed an elongated hole in which the pin of the tibia part during the use of the plateau part in the tibia part and its End of a stop for the pin in the end position of the plateau part and that Forms the center of the pivoting movement. The plateau part comes with its So swivel base with the recessed slot placed on the pin and pushed into the open boundary area until the pin strikes at the end of the elongated hole. In this position, the plateau part with the Swivel pin as pivot axis in the desired way. The advantage this embodiment is an easier replacement of any worn plateau part.
Zur Erhöhung der Stabilität des Gesamtgelenks ist besonders bevorzugt vorgesehen, daß an der medialen Ausmuldung des Plateauteils eine Antiluxationskante angeformt ist. Diese Antiluxationskante umschließt die medial ausgeformte Gleitkufe stärker als dies im Bereich der lateralen Gleitkufe der Fall ist und verhindert so eine Luxation nach medial. Diese Maßnahme unterstützt die Rotationseigenschaft des Rotationsteils am Tibiateil, in dem eine etwaige Luxationsneigung bei Verschwenkungen in Grenzbereichen unter Umständen zu einer erhöhten Luxationsneigung führen könnten.It is particularly preferred to increase the stability of the overall joint provided that a at the medial trough of the plateau part Anti-luxation edge is formed. This anti-luxation edge encloses the medial molded skid more than in the area of the lateral skid and thus prevents dislocation medially. This measure supports the Rotational property of the rotating part on the tibia part, in which any Under certain circumstances, the tendency to dislocate when swiveling in border areas increases could lead to an increased tendency to dislocation.
Die Erfindung wird beispielhaft anhand der nachfolgend erläuterten Zeichnungsfiguren näher erläutert. Hierbei zeigt:The invention is illustrated by way of example with reference to the following Drawing figures explained in more detail. Here shows:

Nachfolgend sind gleiche Teile mit denselben Bezugszeichen versehen.In the following, identical parts are provided with the same reference symbols.
Einen ersten Überblick verschaffen die Fig. 1 und 2, die die drei Komponenten der Sprunggelenkendoprothese, das Tibiateil 1, das Talusteil 2 und das Plateauteil 3 in perspektivischer Darstellung aus unterschiedlichen Richtungen zeigen.A first gain an overview of FIGS. 1 and 2, showing the three components of the total ankle, the tibia part 1, the Talusteil 2 and the plateau portion 3 in a perspective view from different directions.
Das Plateauteil 3 weist zwei taluswärts zugewandte Ausmuldungen 5 und 6 auf, die von einem Mittelstege 4 getrennt sind. Die Ausmuldungen 5 und 6 dienen als Gleitflächen für entsprechend konvex ausgebildete Gleitkufen 7 und 8, die auf der tibiawärts zugewandten Oberfläche des Talusteils 2 ausgeformt sind. Die Gleitkufen 7 und 8 sind von einer dem Mittelsteg 4 des Plateauteils 3 entsprechenden Rinne 9 voneinander getrennt. Dar Plateauteil 3 ist vorliegend gebildet aus einem Schwenksockel 12 sowie aus einem Abschnitt 13, in welchem die Ausmuldungen 5 und 6 ausgebildet sind. Der Schwenksockel 12 ist dazu konzipiert, mit dem Tibiateil 1 an dessen Unterseite zusammenzuarbeiten. Hierzu weist das Tibiateil 1 talusseitig eine kastenförmige Begrenzungskante 11 auf. Der Schwenksockel 12 wird in die Umfassung der Begrenzungskante 11 geschoben. Allerdings weist das Tibiateil 1 in diesem Bereich einen Zapfen 10 auf, um den das Plateauteil 3 nach Zusammenbau der Endoprothese in einem Winkel α (Fig. 4, Fig. 7) im Bereich von -5° bis +5° schwenkbar gelagert sein soll. Hierzu ist in den Schwenksockel 12 ein Langloch 15 (Fig. 2, Fig. 4) vorgesehen, entlang dessen der Zapfen 10 beim Einsetzen des Plateauteils 3 in die Umfassung durch die Begrenzungskante 11 geführt wird. Am Ende des Langlochs 15 findet der Zapfen 10 seinen Anschlag. Hierdurch findet das Plateauteil 3 seine Schwenkachse in Form des Zapfens 10.The plateau part 3 has two troughs 5 and 6 facing towards the valley, which are separated by a central web 4 . The troughs 5 and 6 serve as sliding surfaces for correspondingly convexly designed skids 7 and 8 , which are formed on the surface of the talus part 2 facing towards the tibia. The skids 7 and 8 are separated from one another by a groove 9 corresponding to the central web 4 of the plateau part 3 . The plateau part 3 is formed in the present case from a swivel base 12 and from a section 13 in which the troughs 5 and 6 are formed. The swivel base 12 is designed to work together with the tibia part 1 on its underside. For this purpose, the tibia part 1 has a box-shaped boundary edge 11 on the talus side. The swivel base 12 is pushed into the periphery of the boundary edge 11 . However, in this area the tibia part 1 has a pin 10 , about which the plateau part 3, after assembly of the endoprosthesis, should be pivoted at an angle α ( FIG. 4, FIG. 7) in the range from -5 ° to + 5 °. For this purpose, an elongated hole 15 ( FIG. 2, FIG. 4) is provided in the swivel base 12 , along which the pin 10 is guided through the boundary edge 11 when the plateau part 3 is inserted into the enclosure. At the end of the elongated hole 15 , the pin 10 finds its stop. As a result, the plateau part 3 finds its pivot axis in the form of the pin 10 .
Die Formgebung des Schwenksockels 12 bestimmt nun maßgeblich die Größe des Verschwenkwinkels α, dadurch, daß ab einem Winkel, der < α wäre, die Außenkonturen des Schwenksockels 12 an der Begrenzungskante 11 zum Anschlag kommen.The shape of the swivel base 12 now decisively determines the size of the swivel angle α, in that from an angle that would be <α, the outer contours of the swivel base 12 come to a stop at the boundary edge 11 .
Fig. 3 zeigt eine Schnittansicht durch das zusammengesetzte Implantat mit den vorbeschriebenen Eigenschaften. Vorliegend ist noch dargestellt, wie an der medialen Ausmuldung 6 im Plateauteil 3 eine Antiluxationskante 16 angeformt ist, um dem Gesamtgelenk eine noch höhere Gesamtstabilität zu verleihen. Fig. 3 shows a sectional view through the assembled implant with the properties described above. In the present case it is also shown how an anti-luxation edge 16 is formed on the medial trough 6 in the plateau part 3 in order to give the overall joint an even higher overall stability.
Fig. 5 zeigt eine ganz ähnliche Ansicht wie Fig. 3, allerdings mit fehlender Antiluxationskante. Diese könnte beispielsweise fortgelassen werden bei einem kleineren Schwenkbereich als der bereits oben angegebene. Fig. 5 shows a view very similar to Fig. 3, but with no anti-luxation edge. For example, this could be omitted for a smaller swivel range than that already specified above.
Fig. 6 zeigt eine ähnliche Ansicht wie Fig. 5, allerdings mit einer umlaufenden Einfassung der kastenförmigen Begrenzungskante 11' (Fig. 7). Hier wird der Schwenksockel 12 des Plateauteils 3 vollständig von der Begrenzungskante 11' umfaßt. Der Zapfen 10 findet sein Widerlager in der Ausnehmung 14 in dem Plateauteil 3. Auch hier liegen die Außenkonturen des Schwenksockels 12 die Größe des Verschwenkbereichs fest. FIG. 6 shows a view similar to FIG. 5, but with an all-round edging of the box-shaped boundary edge 11 '( FIG. 7). Here, the pivot base 12 of the plateau part 3 is completely surrounded by the boundary edge 11 '. The pin 10 finds its abutment in the recess 14 in the plateau part 3 . Here, too, the outer contours of the swivel base 12 determine the size of the swivel area.
