Abstract:
1. A method for preparing a space in bone of a human body to receive an insert at least in part therein, said method being performed with a device having an end portion with a mid-longitudinal axis and a first rotatable abrading element having a first abrading surface and a second rotatable abrading element having a second abrading surface, each of the first and second abrading surfaces having a length in a direction along the mid-longitudinal axis and a width transverse to the length, said method comprising the acts of: activating the device to cause the first and second abrading surfaces to move; contacting the first abrading surface of the first abrading element against a first bone portion to remove bone therefrom and the second abrading surface of the second abrading element against a second bone portion to remove bone therefrom, the first and second abrading surfaces being in contact with the first and second bone portions, respectively, along a majority of the length of the first and second abrading surfaces, the first and second abrading surfaces forming surfaces on the first and second bone portions to create the space, the space having a maximum width substantially matching the width of the first and second abrading elements and a maximum length being at least one half the length of the first and second abrading surfaces; rotating, during the act of contacting, the first and second abrading elements about axes different from the mid-longitudinal axis of the end portion of the device; removing the first and second abrading surfaces from the space; and positioning an insert into the space created in the bone.
