Method of preparing a femur for implantation of a femoral implant

摘要

A method of preparing a distal femur for implantation of a femoral implant is described. The distal femur is resected to accommodate placement of a trial implant thereon. The trial implant is then placed against the resected distal femur to locate an optimal position for the femoral implant. The trial implant comprises one or more apertures through which holes are drilled in the distal femur and into which trial pegs are inserted into the distal femur to secure the trial implant to the distal femur. The surgeon then evaluates whether the holes in the femur are located appropriately to securely implant the femoral implant onto the femur. The trial implant is ultimately removed in favor of a final implant.

1. A method of preparing a distal femur for implantation of a femoral implant, comprising the steps of:
making at least one resection in the distal femur; selecting a trial femoral implant to be implanted on the distal femur, the trial implant including a first aperture; placing the trial implant on the resected distal femur; drilling a first peg hole in the femur through the first aperture; inserting a trial peg through the first aperture and into the first peg hole formed in the distal femur; evaluating the spacing of a knee joint, including contacting and moving the trial femoral implant with respect to a tibial trial implant through a full range of motion while the trial peg is inserted through the first aperture and into the first peg hole formed in the distal femur; removing the trial peg from the distal femur; removing the trial implant from the femur; and implanting a femoral implant having a first peg, the first peg disposed in the first peg hole when the femoral implant is implanted.
