An adapter and associated method is provided. One of the many embodiments of the present application is comprised of a one-piece adapter attachable along the backside of the shell component of an acetabular reaming tool, and having a geometric configuration approximating an annular collar. The adapter has a smooth peripheral surface including an area of greater circumference converging to an area of lesser circumference. When the adapter attaches to an acetabular grater shell component, the area of greater outer circumference is proximal to, and traverses the theoretical equator of, the shell component, and the area of lesser outer circumference is distal to the shell component and is the leading end of the adapter when the reaming tool is extracted from the surgical site. The contours and smooth surface of the adapter facilitate fast, safe, unimpeded extraction.
