Abstract
Methods and systems for finish cutting of bone cavities rely on making a plurality of axial finish cuts along the cavity wall. Finish cuts are made using a rotary cutter, and a sufficient number of cuts are made to limit the radial height of cusps between adjacent cuts resulting from the arcuate shape of the cut profile. Cutting time is reduced by selectively terminating the axial lengths of the finish cuts in a manner which does not result in unacceptably high radial cusp heights between adjacent cuts.
