MEDICAL INSTRUMENT AND PROCEDURE

摘要

16 MEDICAL INSTRUMENT AND PROCEDURE 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 prothesis 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 prothesis stem seats in the finished canal accurately.
