Claims14
A method of preparing a bone surface for receiving an implant with an instrument having a shaft and a generally cylindrical tip, the tip having an outer surface wherein a first portion of the outer surface comprises an abrading element and a remaining portion of the outer surface comprises a gripping element, comprising the steps of:
- a) inserting the gripping element of the tip of the instrument into a disc space;
- b) applying a compressive force on the shaft of the instrument to allow the gripping surface to contact a first bone surface without altering the shape of the first bone surface;
- and
- c) rotating the shaft about its longitudinal axis such that the abrading element cuts a second bone surface in a direction perpendicular to the longitudinal axis of the shaft,
- wherein the cutting of the second bone surface occurs without altering the shape of the first bone surface.
