<p>An abrading element (18) for preparing a space between adjacent vertebral bodies to receive an insert, the abrading element being mountable on a shaft (15) of an apparatus capable of rotating said abrading element to cause said abrading element to create at least one surface having a predetermined contour in the end plate of at least one of the adjacent vertebral bodies, said abrading element comprising:
at least one abrading surface (19) having a width selected to substantially match the overall width of the insert to be received between the adjacent vertebral bodies, said abrading element being adapted to be rotated about an axis generally perpendicular to a longitudinal axis of the shaft of the apparatus.</p> |
