1. An orthopaedic surgical instrument system, comprising:
a first broach including (i) a distal-most end configured to be separately secured to a handle, (ii) a proximal tip positioned opposite the distal-most end, and (iii) a tapered body extending distally from proximal tip to the distal-most end, the tapered body having a plurality of cutting teeth defined therein, and a second broach including (i) a distal-most end configured to be separately secured to the handle in place of the first broach, (ii) a proximal tip positioned opposite the distal-most end of the second broach, (iii) a first tapered body extending distally from proximal tip, the first tapered body having a plurality of cutting teeth defined therein, and (iv) a second tapered body extending distally from the first tapered body to the distal-most end, the second tapered body having a plurality of cutting teeth defined therein, wherein the tapered body of the first broach and the first tapered body of the second broach have a first outer three-dimensional geometry having a first size and a first shape such that the tapered body of the first broach and the first tapered body of the second broach are configured to define cavity sections in a patient's bone having the same size and shape, and the second tapered body has a second outer three-dimensional geometry different from the first outer three-dimensional geometry having a second size and a second shape that are different from the first size and the first shape of the first outer three-dimensional geometry, wherein the first outer three-dimensional geometry of the tapered body is defined by the tips of the plurality of cutting teeth of the tapered body, the first outer three-dimensional geometry of the first tapered body is defined by the tips of the plurality of cutting teeth of the first tapered body, and the second outer three-dimensional geometry is defined by the tips of the plurality of cutting teeth of the second tapered body, wherein (i) the tip of each cutting tooth of the first outer three-dimensional geometry has a maximum medial-lateral dimension, (ii) the tip of each cutting tooth defining the second outer three-dimensional geometry has a maximum medial-lateral dimension, and (iii) the maximum medial-lateral dimension of the tip of each cutting tooth defining the first outer three-dimensional geometry is less than the maximum medial-lateral dimension of the tip of each cutting tooth defining the second outer three-dimensional geometry, and wherein (i) the maximum medial-lateral dimension of the tip of each cutting tooth defining the first outer three-dimensional geometry is greater than or equal to a maximum medial-lateral dimension of a first tapered body of a femoral metaphyseal sleeve, and (ii) the maximum medial-lateral dimension of the tip of each cutting tooth defining the second outer three-dimensional geometry is less than a maximum medial-lateral dimension of a second tapered body of the femoral metaphyseal sleeve. |
