Combined femoral stem

The invention relates to the technical field of medical prostheses, in particular to a combined femoral stem. The combined femoral stem comprises a stem body, a femoral neck and a filling layer, wherein the stem body is provided with a mounting groove; one end of the femoral neck extends into a mounting groove; the filling layer is stuffed between the femoral neck and the inner wall of the mounting groove, and the filling layer is fixedly connected with the stem body and the femoral neck. According to the combined femoral stem, the stem body and the femoral neck are of a split structure, the femoral neck with different forward inclination angles can be prepared, the combined femoral stem can adapt to wider forward inclination angle changes, the choice of a patient is increased, and besides, compared with an existing integrated femoral stem structure, the production cost can be reduced. The femoral neck and the stem body are connected through the filling layer, so that connection firmness of the femoral neck a
