A joint implant component () for administering a pharmaceutical product is disclosed, which comprises an implant shaft (), a joint section () arranged at the proximal end of the implant shaft, a flush supply opening () and a backflush opening (). At least one shaft flush channel () and one shaft backflush channel () extend along the implant shaft inside the implant shaft. The shaft flush channel is connected to the outside of the implant shaft via shaft flush holes () for discharging the pharmaceutical product, and the shaft backflush channel is connected to the outside of the implant shaft via at least one shaft backflush hole () for receiving the discharged pharmaceutical product. The flush supply opening is fluidically connected to the proximal end of the shaft flush channel and the backflush opening is fluidically connected to the proximal end of the shaft backflush channel. Also disclosed is a joint implant comprising two such joint implant components which are connected to one another by means of joint surface parts () and are pivotable relative to one another.

Joint implant for administering a pharmaceutical product

Hip joint implant for fastening to a pelvic bone (), with a support body which has a socket () and whose convex outer face is designed to bear on the pelvic bone () and which, on its concave inner face, has a receiving seat for a pelvis-side bearing that is designed to receive a joint head of a femoral component of a hip prosthesis, and with outwardly directed flat fastening brackets () which are arranged at the edge region of the socket () and are each provided with at least one receiving seat for a fastening means. The fastening brackets () are made of a reshapeable biocompatible material and are connected to the socket () via a non-releasable cohesive bond (), wherein the socket () is made of another, stiffer biocompatible material. A high degree of robustness of the socket () is thus combined with what is, by virtue of the reshapeability, an improved adaptation to the anatomical conditions of the respective pelvic bone. This improves reliability of fastening, stability and long-term behavior.
