Claim:
1. A surgical instrument assembly for use during a surgical procedure to implant an orthopaedic hip prosthesis, comprising: a version-replicating instrument comprising an elongated shaft having (i) an alignment key formed in a distal end thereof, the alignment key having a longitudinal axis, and (ii) an alignment slot formed in an opposite, proximal end thereof, the alignment slot having a longitudinal axis that lies on the same imaginary line as the longitudinal axis of the alignment key, and a proximal trial instrument including: wherein (i) a hole is defined in the proximal end of the elongated shaft that extends in a direction parallel to the longitudinal axes of the alignment slot and the alignment key, and (ii) the alignment slot extends inwardly through an outer surface of the elongated shaft and opens into the hole, and wherein when the proximal trial instrument is secured to the version-replicating instrument, the alignment key of the proximal trial instrument is positioned in the alignment slot of the version-replicating instrument to align the proximal trial instrument in a predetermined orientation relative to the version-replicating instrument.
