ABSTRACT:
A method of implanting a hip prosthesis includes utilization of a device at the implantation site to confirm that the femoral prosthesis will have a neck length corresponding to a preoperative plan. First, a desired neck size for the femoral prosthesis is determined. Then, the femoral prosthesis is positioned in the femur. Next, a locator rod component is advanced toward the femoral prosthesis along an axis parallel to the longitudinal axis of the femoral prosthesis until a greater trochanter locator mounted on the side of the locator rod component is as close as possible to contacting the greater trochanter of the femur. Next, a neck sizing component, which has neck size markings on its outer surface, is placed on the neck projection of the femoral prosthesis. Finally, a reference distance is determined by identifying which of the reference distance markings of the locator rod component corresponds to a desired neck size marking on the neck measuring device along a line substantially perpendicular to the longitudinal axis of the femoral prosthesis. The determined reference distance should correspond to a planned reference distance that was determined in an appropriate preoperative templating and measuring procedure.
