Abstract

An orthopaedic surgical instrument system includes a first broach including a first end configured to be separately secured to a handle and a tapered body having a plurality of cutting teeth defined therein, and a second broach including a first end configured to be separately secured to the handle in place of the first broach, a first tapered body extending distally from a second end positioned opposite the first end, and a second tapered body extending distally from the first tapered body. The tapered body of the first broach and the first tapered body of the second broach have a first outer geometry and the second tapered body has a second outer geometry different from the first outer geometry.
