Abstract:
An orthopedic implant in the form of a hip joint endoprosthesis consists of a head, which is set onto an anchoring shaft, which itself is insertable into a bone and anchorable therein. The head comprises an inner blind-hole-type recess, and the anchoring shaft is provided with a tenon for inserting into this recess. A sleeve provided with an approximately central through-bore is soldered into the recess of the head, via which sleeve the head is setable or mountable on the tenon. The head consists of a ceramic based on zirconium dioxide, aluminum oxide or a mixed ceramic, while the sleeve consists of a high strength titanium material. The connection between the head and the sleeve is produced by a silicate ceramic solder that solidifies or hardens in a ceramic firing, as well as by a subsequently applied glass solder, of which the excess can exit via the through-bore into a hollow space existing between the sleeve and the tenon. Both the recess of the head as well as the metallic sleeve are embodied approximately cylinder-shaped.

Claim (Index 1):
An orthopedic implant in the form of a femoral component of a hip joint endoprosthesis with a head consisting of a ceramic material, which is set onto an anchoring shaft, which itself is insertable into a bone and anchorable therein, wherein the ceramic head comprises an approximately cylinder-shaped blind-hole-type inner recess and the anchoring shaft is provided with a tenon for inserting into this recess, wherein a similarly approximately cylinder-shaped metallic sleeve is soldered into the recess of the head, via which the ceramic head is connectable with the tenon, wherein the sleeve ( 5 ) is pre-coated by a first silicate glass solder ( 9 ) that solidifies or hardens in a ceramic firing, wherein the connection between the ceramic head and the sleeve is produced via a second silicate glass solder ( 8 ), and wherein the covering surface of the sleeve ( 5 ) comprises an approximately central through-bore ( 7 ), through which excess liquid second glass solder ( 9 ) can escape into a hollow space ( 10 ) existing between the sleeve ( 5 ) and the seat ( 2 ) of the shaft ( 1 ).
