The endoprosthesis has a cone coupling between an anchoring part and a joint part, which is provided with a fixing screw (8). The cone point of the screw co-operates with an eccentric bore. The cone coupling also has a rotation-prevention arrangement of pins (13) and grooves (14), as well as the fixing screw. The pins and grooves are formed as projections and recess in the anchoring and joint parts, which co-operate over parallel flanks (16,17). |
