Patient-specific registration jig and associated method for registering an orthopaedic surgical instrument to a patient

A method for registering an orthopaedic surgical instrument with a bony anatomy of a patient, the method comprising:

• attaching a patient-specific registration jig to an orthopaedic surgical instrument, the patient-specific registration jig having a head and an adaptor coupled to the head and extending longitudinally therefrom, wherein the head includes a patient-specific contact surface configured to contact a portion of the patient's bony anatomy, the patient-specific contact surface includes a patient-specific negative contour configured to receive a portion of the patient's bony anatomy, and the adaptor is configured to be received by a clutch of the orthopaedic surgical instrument;
• coupling the patient-specific registration jig to a portion of the patient's bony anatomy, wherein coupling the patient-specific registration jig comprises inserting the portion of the patient's bony anatomy into the patient-specific negative contour of the head of the patient-specific registration jig;
• and
• controlling a surgical navigation system to register the orthopaedic surgical instrument to the bony anatomy of the patient while the patient-specific registration jig is coupled to the patient's bony anatomy.
