An apparatus and method for reaming a bone, facilitating pre-implantation alignment of a prosthesis using trial components, and preparing a bone site for anti-rotational implantation of the prosthesis is provided. The apparatus includes a boring end, a mating end disposed opposite the boring end, and a keying aid disposed between the boring end and mating end. The method includes attaching a power tool to the mating end, reaming a bone canal with the boring end, detaching the power tool, attaching a trial component, conducting alignment trials, maintaining the apparatus in the desired position, detaching the trial component, cutting at least one keyway in the bone canal using a cutting device and the keying aid, removing the cutting device, removing the apparatus from the reamed bone canal, and inserting the prosthesis into anti-rotational engagement with reamed bone by aligning the key on the prosthesis with the keyway in the bone canal.
