An orthopaedic surgical instrument assembly includes a broach (280) having a tapered outer surface (284), with a plurality of cutting teeth (290) formed on the tapered outer surface. A slot (316) is defined in the upper end of the broach and a broach insert (282) can be positioned in the slot. The broach insert has a tapered outer surface (386), and a plurality of cutting teeth (388) formed on the tapered outer surface. An adaptor (400) has a base (402) which can be positioned in the slot of the broach in place of the broach insert, and a shaft (422) extending from the base. An attachment device (12) has a passageway (64) formed within it which can receive the shaft of the adaptor, and a cutting block (14) can be coupled to the attachment device.
