Abstract
The disclosed subject matter relates to a system and method for preparing a surface of a bone proximate a joint, in which the preparation includes boring a plurality of arced channels/troughs in the bone surface using an arch drill assembly guided by plural guide bores along a predetermined longitudinal arc. The bored troughs create a scalloped surface on the bone to which an inverse contoured joint insert/implant having cooperating convex ridges engages. The plural guide bores are also defined by the predetermined longitudinal arc which may be circular or helical. The disclosed subject matter minimizes bone removal and allows greater access options for preparing the bone surface.
