An implant for an endoprosthesis for human or veterinary use, and for mounting on the end of a femur. A spherical surfaced cap member with a frusto conical surfaced central opening fits over the neck of a femur and includes a thrust plate received in the femur for transmitting thrust forces from the femur to the cap member. The frusto conical surface may be grooved and include recesses and projections for improving bonding with the femur and the thrust plate may have mechanical retaining means for the cap or be screw fastened to the femur.
