Claim:
1. A method of using a dummy implant to size a femur to receive a femoral component implant during a hip replacement surgical procedure, the method comprising: providing a dummy implant comprising a footplate at a proximal end with a cross-sectional size that replicates a proximal portion of the femoral component implant, a distal section with a cross-sectional size that replicates a distal portion of the femoral component implant, and an intermediate shaft that extends between the footplate and the distal section with a smaller cross-sectional size than an intermediate portion of the femoral component implant, the footplate extending radially outwardly beyond the shaft and the distal section having a distal end; inserting the dummy implant into a femoral canal of the femur and contacting the distal section of the dummy implant against a wall of the femoral canal and with the shaft extending along the femoral canal and being spaced away from the wall of the femoral canal; contacting the footplate of the dummy implant against a proximal end of the femur while the distal section is contacting the wall of the femoral canal and the distal end is positioned at a first position within the femoral canal; visually determining an expected position of the femoral component implant relative to the femur based on visually observing the footplate relative to the proximal end of the femur; removing the dummy implant from the femoral canal; and inserting the femoral component implant into the femoral canal, the femoral component implant having a different length than the dummy implant such that a distal end of the femoral component implant is positioned away from the first position when the femoral component implant is positioned in the femoral canal.
