1. A surgical instrument assembly operable to ream an intramedullary canal of a patient's femur during a surgical procedure to implant a distal stem component of a modular orthopaedic hip prosthesis, comprising:
a distal reamer having (i) a cutting head that includes a plurality of helical cutting flutes arranged in a geometry that corresponds with the geometry of the distal stem component, and (ii) a female drive socket comprising a female hex drive socket, and
an extension tool having (i) an elongated shaft (ii) a connector at a proximal end of the elongated shaft configured to couple the extension tool to a rotary drive source, and (iii) a drive spline positioned at a distal end of the elongated shaft in, and engaged with, the female drive socket of the distal reamer such that rotation of the extension tool causes rotation of the distal reamer,
wherein the extension tool further has a number of visual markings that correspond to depths of the distal reamer within the intramedullary canal of the patient's femur.
