Abstract
A number of orthopaedic surgical instruments for use in a surgical procedure to prepare a patient's femur to receive an orthopedic prosthesis are disclosed.

Claims12
A method for performing an orthopaedic surgical procedure on a patient's femur, the method comprising:
- attaching a stem trial to a proximal end of an offset tool,
- advancing the stem trial and the proximal end of the offset tool through a distal surface of the patient's femur into a distal end of a medullary canal,
- rotating a distal end of the offset tool relative to the stem trial to identify the desired offset orientation,
- advancing a cannulated reamer over the distal end of the offset tool when the distal end is positioned in the desired offset orientation,
- reaming the patient's femur with the cannulated reamer,
- securing a distal end of an intramedullary orthopaedic surgical instrument to a proximal end of an intramedullary adaptor,
- rotating a first adaptor body of the intramedullary adaptor to a desired offset orientation relative to a second adaptor body of the intramedullary adaptor,
- advancing the intramedullary orthopaedic surgical instrument and a proximal end of the intramedullary adaptor through the distal surface of the femur, and
- positioning a surgical block secured to a distal end of the intramedullary adaptor on the distal surface of the femur.
