1. A medical device for preparing an elongated bone for receiving an implant comprising:

  • a femoral guide having a patient-specific three-dimensional bone-engaging surface configured according to a preoperative plan based on a three-dimensional image model of a proximal femoral bone to mate complementarily with the surface of the proximal femoral bone extending between a greater trochanter, a femoral neck and a femoral shaft of the proximal femoral bone, the femoral guide including a first guide end forming a planar guide configured to engage a resection tool within a desired resection plane and thereby guide the resection tool as the resection tool cuts the femoral neck along the desired resection plane and completely removes a femoral head of the proximal femoral bone but preserves the greater trochanter; and

    an elongated alignment member removably attachable to the femoral guide and defining a reference axis for guiding a cutting tool into the proximal femoral bone through a resected surface of the femoral neck.
