Abstract
The kit contains a metal outer shell (1), an inner shell (2) which can be inserted therein, and fastening elements which can be mounted on the outer shell (1) so that they substantially protrude radially, and which include at least one support (4) and two screw connections (5). The fastening elements, which can be designed with varying support lengths, together with the outer shell (1) form a tripod, which positions the outer shell (1) outside the osseous tissue (6). The outer shell (1) is designed all around with through-holes (17) mounted at different angles (14), which permit the mounting of the screw connections (5) in correspondingly different angular positions with respect to the support (4). The kit, which by simple means enables an optimal adjustment of the acetabulum which can be corrected during implantation if necessary, is provided as a replacement for a missing pelvic part in the region of the hip joint
