Abstract
A milling instrument for use in orthopaedic surgery includes an elongate stem for insertion into a prepared intramedullary canal of a bone. A pivotable mill includes a base connected to the stem and a cutting head pivotally connected to the base about a pivot axis. The cutting head has an axis of rotation and is rotatable about the axis of rotation. The cutting head has a first abutment surface positioned relative to the pivot axis and the base has a second abutment surface positioned relative to the pivot axis. The first abutment surface and the second abutment surface abut each other upon pivoting of the cutting head relative to the base at a predetermined angle and thereby limit the pivoting therebetween.
