ABSTRACT:
A medical instrument and procedure mills a groove at a precise angle and location in a partially formed bone canal that has been drilled and reamed to provide a frustoconical seat for a prosthesis stem that has a conical proximal region. The groove finishes preparation of the canal in a precise manner so that an anti-rotation lug attached to the conical proximal region of the prosthesis stem seats in the finished canal accurately.
