Abstract
A surgical instrument assembly includes a metallic hemispherical component and a driver component removably coupled to the hemispherical component. The metallic hemispherical component has a convex outer surface configured to engage a patient's natural acetabulum, a concave inner surface positioned opposite the outer surface and defining a cavity in the hemispherical component, a plurality of cutting teeth extending outwardly from the outer surface, and a plurality of apertures defined in the inner surface. The driver component has a shank and a plurality of ribs secured to, and extending outwardly from, the shank. Each rib has a tab that is received in a corresponding aperture of the hemispherical component to secure the driver component to the hemispherical component.
