Abstract
The invention is directed to an orthopaedic instrumentation assembly 10 for at least partially preparing an end of a bone with a drill for receiving a prosthesis. The instrumentation assembly includes a drill guide 14 having a drill guide opening for guiding a drill into the bone; and an orthopaedic sizing plate 12 attachable to the end of the bone. The sizing plate 12 is configured for interconnecting with the drill guide 14. The drill guide 14 includes a first drill stop 47 and the sizing plate includes a second drill stop 33, with the first drill stop and the second drill stop coacting with each other for limiting projection and for maintaining axial alignment of the drill into the bone.
