METHOD OF USING A FEMORAL SURGICAL INSTRUMENT

摘要

A method of using an orthopedic surgical instrument assembly that includes an instrument handle configured to clamp a broach and femoral stem trial assembly. A depth stop is configured to removably couple to the instrument handle. When the broach and femoral stem trial are advanced into a medullary canal of a patient's femur, a substantially planar proximal surface of the depth stop is configured to engage the distal surface of the femur, determining the depth of the broach in the medullary canal. The proximal surface of the depth stop is parallel to the joint line, defining an oblique angle to the anatomical axis of the femur. The depth stop may be attached to the instrument handle at a number of positions to control the depth of the broach. The assembly may include a spacer plate removably coupled to the depth stop that distalizes the broach in the medullary canal.

1. A method for surgically preparing a distal end of a femur to receive an orthopedic 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.
