Abstract

A shoulder prosthesis replaces the condyle (12) of the upper arm bone (10) and the acetabulum of the shoulder blade by a cup (40). The condyle (12) is made of Ti or of a Ti alloy and the element (40) is made of plastic material, pref. RCH100 CHIRULEN (RTM). The part-spherical contact surface (18) of the condyle is matched to the contact face (42) of the acetabulum. The bolt element (16) has a blind hole (26) with a female thread (28) for the bolt (30) with head (32). The opening angle of the surface (42) from the centre of curvature (20) is max. 180 deg. Both elements (12, 14), the bolt (30, 32), the sleeve (34) and the studs (46) are coated with a ceramic bone substitute, pref. hydroxyl apatite. ADVANTAGE - This shoulder prosthesis resembles the Oxford knee prosthesis in its function; it corresponds to the movements of the natural shoulder and simplifies the implantation.

Description

Die Erfindung betrifft eine Schulterprothese mit einem die Gelenkkugel des Oberarmknochens ersetzenden Gelenkelement und einem die Gelenkpfanne des Schulterblattes ersetzenden Pfannenelement, wobei das Gelenkelement eine konvexe teilkugelförmige Gelenkberührungsfläche aufweist, die an die konkave teilkugelförmige Gelenkberührungsfläche des Pfannenelementes bezügliche Krümmungsradius angepaßt ist. The invention relates to a shoulder prosthesis having a the joint ball of the humerus replaced hinge element and a the joint socket of the shoulder blade replacing pan member, said joint member having a convex part-spherical articulating contact area related to the concave part spherical articulating contact surface of the socket element radius of curvature is adjusted.

Eine derartige Schulterprothese ist bspw. aus dem Firmenprospekt 1982 OEC Internatiional, A-41, ALIVIUM Total Shoulder Replacements, Stanmore Total Shoulder, bekannt. Such a shoulder prosthesis is, for example, from the company brochure 1982 OEC Internatiional, A-41, ALIVIUM Total Shoulder Replacements, Stanmore Total Shoulder known. Bei dieser bekannten Schulterprothese handelt es sich um eine Modifikation bekannter Hüftgelenkprothesen, wobei sich durch das lanzenartige Befestigungsteil, das mit dem Gelenkelement einstückig verbunden ist, und das im Oberarmknochen fixiert wird, ein gewisser Herstellungsaufwand sowie ein nicht unerheblicher Implantationsaufwand ergibt. In this known shoulder prosthesis is a modification of a known hip prostheses, said results by the lance-like fitting part, which is integrally connected to the joint element, and which is fixed in the humerus, a certain manufacturing cost as well as a considerable implantation effort.

In der Kniegelenk-Prothetik ist ua ein sog. Oxford-Kniegelenk bekannt, das in seiner Bewegungsfunktion ein natürliches Kniegelenk gut annähert. In the knee joint prosthesis is known, among other things, a so-called. Oxford knee that approximates a natural knee joint well in its movement function.

Der Erfindung liegt die Aufgabe zugrunde, eine Schulterprothese der eingangs genannten Art zu schaffen, die bezüglich ihrer Bewegungsfunktion ähnlich wie ein Oxford-Kniegelenk funktioniert, dh die einen Bewegungsablauf besitzt, welcher dem Bewegungsablauf eines natürlichen Schultergelenkes ohne große Einschränkungen entspricht, und deren Implantation einfach möglich ist. The invention has for its object to provide a shoulder prosthesis of the aforementioned type that works in terms of their motor function similar to an Oxford knee joint, ie having a movement corresponding to the movement of a natural shoulder joint without major limitations, and their implantation easily possible is.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die teilkugelförmige konvexe Gelenkberührungsfläche des Gelenkelementes an einem Kappenelement vorgesehen ist, das einen Öffnungswinkel aufweist, der kleiner oder höchstens gleich 180 Winkelgrad beträgt, daß vom Kappenelement auf der von seiner Gelenkberührungsfläche abgewandten Seite ein Bolzenelement wegsteht, das mit einem von der vom Kappenelement entfernten Stirnfläche ausgehenden Sackloch ausgebildet ist, das einen Innengewindeabschnitt aufweist, daß in das mit dem Innengewindeabschnitt versehene Sackloch zur Fixierung des Gelenkelementes am Oberarmknochen ein Schraubelement einschraubbar ist, das einen Kopf aufweist, und daß die konkave teilkugelförmige Gelenkberührungsfläche des Pfannenelementes von ihrem Krümmungsmittelpunkt ausgehend einen Öffnungswinkel aufweist, der kleiner als 180 Winkelgrad ist. This object is inventively achieved in that the part-spherical convex articulating contact surface of the joint element is provided on a cap member having an opening angle which is smaller or at most equal 180 angular degrees, that the cap member on the side away from its articulating contact surface side protrudes a bolt element with is formed an outgoing from the remote from the cap member end face of blind hole having an internally threaded portion that, in the provided with the internal thread portion blind hole for fixing the joint element on the upper arm bone a screw can be screwed which has a head, and that the concave part spherical articulating contact surface of the pan member from starting has an opening angle its center of curvature which is smaller than 180 degrees of angle.

Durch eine solche Ausbildung der Schulterprothese, dh des Gelenkelementes und des mit dem Gelenkelement gelenkig verbundenen Pfannenelementes ergibt sich zwischen den zuletzt genannten Elementen ein Bewegungsablauf, der dem Bewegungsablauf eines natürlichen Schultergelenkes weitestgehend entspricht. Such a configuration of the shoulder prosthesis, that is the hinge member and the articulated joint member with the socket member is formed between the last-mentioned elements, a sequence of movements largely corresponds to the movement of a natural shoulder joint. Durch die Ausbildung des Gelenkelementes mit einem Bolzenelement und durch die Möglichkeit, mit dem Bolzenelement ein Schraubelement mechanisch fest zu verbinden, ist es vergleichsweise einfach möglich, das Gelenkelement mit einem entsprechend vorbereiteten Oberarmknochen mechanisch fest zu verbinden. By forming the joint member with a bolt member and through the possibility to connect with the bolt element is a screw element mechanically fixed, it is relatively easily possible to connect the hinge element mechanically fixed to an appropriately prepared humerus. Dabei besteht sowohl die Möglichkeit, die Schulterprothese einzuzementieren, als auch die Möglichkeit, die Schulterprothese zementfrei zu implantieren. Here is both the opportunity to cement his shoulder prosthesis, as well as the opportunity to implant the shoulder prosthesis without cement.

Das Kappenelement der erfindungsgemäßen Schulterprothese weist vorzugsweise einen mindestens annäherend kreisförmigen Umfangsrand auf. The cap element of the shoulder prosthesis according to the invention preferably has an at least annäherend circular peripheral edge. Als zweckmäßig hat es sich erwiesen, wenn das Pfannenelement der Schulterprothese einen abgerundet eckigen Umfangsrand aufweist. It has proved to be advantageous if the socket element of the shoulder prosthesis having a rounded polygonal peripheral edge. Durch eine solche Ausbildung ergibt sich für die Schulterprothese bei einem kleinen Platzbedarf eine gute Beweglichkeit. Such a design results for the shoulder prosthesis with a small footprint good mobility. Der Umfangsrand des Pfannenelementes ist zu diesem Zwecke vorzugsweise abgerundet rechteckig ausgebildet. The peripheral edge of the socket element is formed preferably rounded rectangular for this purpose.
