ABSTRACT:
A kit for implanting a socket joint implant has an outer cup (1), an inner cup (2) and fasteners (3, 3a) which are fitted to radially project from the outer cup (1). Each fastener includes a bearer plate (17) arranged on a shaft-like supporting part (18) which is able to bear in an anchoring bore (6) in the bone tissue (5), and a head part (20) which is connected detachably to the supporting part (18) and can be screwed tight from the inside of the outer cup (1) into a guide bore (11) of the cup. The supporting part (18) has a diameter (A) which is less than the diameter (d1) of the guide bore (11). The kit is pre-assembled outside the region of implantation and positioned in the region of implantation while the fasteners (3, 3a) are pulled in towards the center of the outer cup (1). The fasteners (3, 3a) are then pushed into the anchoring bores ( 6) and screwed tight to the outer cup (1) with head parts (20). The kit is adaptable to different anatomical conditions and may be employed as a replacement for a part of the pelvis missing in the region of the hip socket.
