Femoral orthopaedic surgical instrument including a measurement device and method of use of same

摘要

An orthopedic surgical instrument assembly is disclosed. The assembly includes an orthopedic surgical instrument including a first surface, and a measurement gauge removably coupled to the orthopedic surgical instrument. The gauge includes an arm having a tip positioned proximal to the orthopedic surgical instrument, and a plurality of markings defined on the arm. Each marking indicates a predetermined distance from the first surface of the orthopedic surgical instrument. The assembly may be used during an orthopedic surgical procedure on a femur, which is also described herein.

1. A method for performing an orthopaedic surgical procedure on a femur including a medial epicondyle, a lateral epicondyle, and an epicondylar axis extending through the medial epicondyle and the lateral epicondyle, the method comprising:
assembling an orthopaedic surgical instrument assembly by securing an intramedullary orthopaedic surgical instrument to a base plate such that a proximal end of the intramedullary orthopaedic surgical instrument is positioned proximal to the base plate, and securing a measurement gauge to the base plate such that a proximal end of the measurement gauge is positioned proximal to the base plate, inserting the proximal end of the intramedullary orthopaedic surgical instrument into a distal opening of a medullary canal of the femur, advancing the intramedullary orthopaedic surgical instrument proximally along the medullary canal to move the base plate toward the femur, and aligning a marking of the gauge with an end of the epicondylar axis such that the distal surface of the base plate is positioned a predetermined distance from the epicondylar axis, wherein the marking is positioned between the proximal end of the measurement gauge and the distal surface.
