Customized patient-specific revision surgical instruments and method

1. A method of fabricating a customized patient-specific guide block, the method comprising:

generating a image of a patient's bony anatomy and an implanted prosthetic component secured to the patient's bony anatomy,

identifying landmarks on the patient's bony anatomy and the prosthetic component,

selecting a revision surgical instrument based the image and the landmarks, and

manufacturing the customized patient-specific guide block including a customized prosthesis-specific negative contour shaped to match a corresponding contour of the implanted prosthetic component, the customized prosthesis-specific negative contour includes a concave surface shaped to match a convex surface of the corresponding contour of the implanted prosthetic component.

2. The method of claim 1 , wherein selecting the revision surgical instrument includes generating a second image showing a planned position of the revision surgical instrument relative the patient's bony anatomy.

3. The method of claim 2 , further comprising manufacturing a second customized patient-specific guide block based on the planned position of the revision surgical instrument, the second customized patient-specific guide block including an indicator of the planned position.

4. The method of claim 1 , further comprising selecting a revision orthopaedic prosthesis based the image and the landmarks.

5. The method of claim 4 , wherein selecting the revision orthopaedic prosthesis:

selecting a first revision orthopaedic prosthesis from a plurality of revision orthopaedic prostheses,

overlaying a digital template of the first revision orthopaedic prosthesis on the image to create a second image showing the first revision orthopaedic prosthesis implanted in the patient's bone, and

selecting a second revision orthopaedic prosthesis from the plurality of revision orthopaedic prostheses based on the second image.
