A method of designing a set of contoured implants for fixation to a bone of a patient, includes obtaining a set of virtual bone models of the bone, selecting a plurality of points on an outer surface of each virtual bone model in the set of virtual bone models, manufacturing a set of implants, each implant corresponding to a respective virtual bone model and having fixation holes corresponding to the selected plurality of points on the outer surface of the respective virtual bone model, contouring each implant in the set of implants and selecting a contoured implant from the set of implants for fixation to the bone of the patient such that the selected contoured implant corresponds to a size of the bone of the patient.
