摘要:
The invention relates to a prosthesis comprising a first component (10) and a second component (60), wherein the first and second components have respective inter- engaging parts (24,64) and wherein at least one of the first or second components comprises an anti- rotational element (32,66) configured to resist rotational movement between the inter- engaging parts and wherein the inter- engaging parts share an axis of rotation such that they are engageable in a plurality of relatively rotated positions and wherein the axis of rotation of the inter- engaging part of one of the first or second components is parallel to but offset from a central axis of said first or second component.

The invention relates to an endoprosthesis, particularly for the at least partial replacement of a hollow bone, comprising a plug-in connection for connecting a shaft (2) to a further prosthesis part (1), wherein the plug-in connection (3) comprises an axial projection (33) and a receptacle (34). The invention provides that a radial transverse channel (53) is provided on one part of the plug-in connection (3), said channel engaging behind the plug-in connection and having a center axis (55) that is offset (d) relative to the axis (56) of a transverse bore (52) disposed on the other part of the plug-in connection, and a clamping element (6) for insertion into the transverse channel (53), the point (62) of said clamping element engaging into the transverse bore (52) in the assembled state. In this manner an effective safety may be achieved, even in the event of unfavorable tolerance pairing, without having an adverse effect on the sensitive projection.
摘要:
Gegenstand der Erfindung ist ein Deckel für einen Wirbelkörperplatzhalter mit einem zylindrischen Innenkörper (12), der in einem koaxial angeordneten, hülsenförmigen Außenkörper (10) teleskopartig einschiebbar ist, wobei der Deckel (14) an einer Stirnseite des Innenkörpers (12) und/oder an einer Stirnseite des Außenkörpers (10) anbringbar ist, umfassend eine radial ausgerichtete Deckelwand (16) und ein in den Innenkörper (12) oder den Außenkörper (10) eingreifendes Führungselement (18). Einen Deckel für einen Wirbelkörperplatzhalter der eingangs genannten Art zu schaffen, der ein schnelles und einfaches platzieren, genauso wie ein schnelles und einfaches Ausrichten des Wirbelkörperplatzhalters ermöglicht wird dadurch erreicht, dass die Deckelwand (16) radial über das Führungselement (18) hinaus reicht, wobei das Mittel zum Befestigen des Deckels (14) an einem Wirbelkörper an dem über das Führungselement (18) hinausragenden Teil der Deckelwand (16) angebracht ist.
摘要:
A prosthetic joint assembly that includes a shell (12) including an inner surface. The assembly also includes a bearing member (34) including an outer surface. The bearing member is received by the shell such that the outer surface (36) of the bearing member is adjacent the inner surface (26) of the shell. Furthermore, the joint assembly includes a compressible member (50,56) that is rigidly fixed to the inner surface of the shell or the outer surface of the bearing member to only cover a portion thereof. The compressible member is made of a material that is different from the shell or the bearing member. The compressible member improves the fit between the shell and the bearing member, and prevents micro-motion there between.
