Abstract
A method for making an acetabular reamer cup and an acetabular reamer cup made thereby. The method comprises the steps of fabricating a bowl-shaped cup-blank having an outer surface, an inner surface and a rim, perforating a plurality of holes through the cup-blank, the holes each being surrounded by a margin, deforming outwardly a cutting portion of the margin of each of the holes, smoothing the outer surface of the cup-blank to sharpen the deformed cutting portions, raising cutting edges from the cutting portions and removing the rim. The cutting edges are disposed to cut upon rotation of the acetabular reamer. The cup manufactured by this method is preferred because of its improved strength and consistently superior cutting edges.
