Patent ID: 7749278

Claim:
A method for implanting a selected femoral implant into a femoral medullary canal, the method comprising: (1) selecting a femoral implant for implantation into the femoral medullary canal from a pre-made set of femoral implants comprising a plurality of femoral implants, wherein each femoral implant in the set includes: an upper portion and an insertion portion, the insertion portion including a longitudinal axis, a tip, an insertion portion anterior face, an insertion portion medial face and an insertion portion lateral face; an osteotomy point forming a physical discontinuity between the upper portion and the insertion portion medial face, the osteotomy point located a predetermined distance from the tip, the predetermined distance from the osteotomy point to the tip defining an insertion portion length; the insertion portion medial face and the insertion portion lateral face located a predetermined insertion portion width from each other at a point located twenty millimeters distal to the osteotomy point on the insertion portion medial face; at least some of the femoral implants in the set having an insertion portion length that differs from the insertion portion lengths of other femoral implants in the set; at least some of the femoral implants in the set having an insertion portion width that differs from the insertion portion widths of other femoral implants in the set; wherein the femoral implants in the set are configured such that curved portions of their insertion portion medial faces between their osteotomy point and a point located eighty millimeters distal to the osteotomy point are congruent in shape and length when the femoral implants are aligned such that the longitudinal axes of the insertion portions are parallel; (2) implanting the selected femoral implant.
