Femoral surgical instrument and method of using same

An orthopaedic surgical instrument, comprising:

• a base plate including a first arm, a second arm, and a first channel defined between the first arm and the second arm, the first arm and the second arm defining a non-captured distal cutting guide having a substantially planar proximal surface,
• a mounting bracket coupled to the base plate, the mounting bracket including a first flange, a second flange, and a second channel defined between the first flange and the second flange,
• a locking mechanism configured to secure the orthopaedic surgical instrument to a second orthopaedic surgical instrument,
• wherein (i) the proximal surface defines an imaginary plane, (ii) the second channel defines an axis extending through the imaginary plane, and (iii) an oblique angle is defined between the axis and the imaginary plane.

A method for surgically preparing a distal end of a femur to receive an orthopaedic prosthesis, the method comprising:

• attaching a depth stop to a handle at a first position of a plurality of positions along an elongated body of the handle,
• securing a broach to an end of the handle, the broach having a tapered outer surface with a plurality of cutting teeth defined in the outer surface,
• advancing the broach along an anatomical axis of the femur through a distal opening of a medullary canal of the femur, and
• engaging a proximal surface of the depth stop with a distal surface of the femur, wherein an oblique angle is defined between the proximal surface and the anatomical axis of the femur.
