An implant (10) is provided for replacing the proximal portion of a femur having a substantially intact natural femoral neck (42) and a lateral side opposite the femoral neck (42), with a bore (52) extending from the femoral neck (42) through a lateral side of the femur (40). The implant comprises a sleeve (14) having a flange (28) for engaging a proximally facing resected surface (50) of the neck surrounding the bore (52) in the femur and having a bore (26) with an inwardly tapered conical portion. A shaft member (12) having a longitudinal axis (22), a distal end (38), and a proximal end (18) is placed in the bore through the femur. The shaft member (12) has an intermediate conically tapered male portion (20) for coupling to the conically tapered bore (26) of the sleeve and a proximal end (18) having a conically tapered portion. A head member (16) having a distal end and a proximal substantially-spherical portion and a tapered recess (24) is configured for positioning in a natural or prosthetic hip socket.
