Abstract
The surgical reamer has a hollow dome with apertures spaced apart arranged in arcs extending from an apex of the dome to the base portion of the dome, and removable teeth positioned in the apertures. Each cutting tooth has a flange that is aligned flush with the external surface of the dome, and a raised cutting edge extending above the flange and the external surface of the dome, and an interior passageway communicating between the outside and inside of the dome. In one embodiment, a base plate is removably secured on the base portion of the dome to provide closure of the central cavity of the dome.
