TO THE EDITOR:
In the article "Porous-Coated Acetabular Components with Screw Fixation. Five to Ten-Year Results" (78-A: 975981, July 1996), Latimer and Lachiewicz emphasized that "the outer diameter of the acetabular component that was implanted was the same as the diameter of the final reamer that was used." In other words, they used line-to-line reaming. The authors, who criticized the technique of press-fitting into an underreamed acetabulum, believe that their technique does not create gaps at the polar dome and that the addition of multiple screws improved stability (although no data were given). They did state that "the last reamer was used only briefly at the acetabular rim."
A brief review of geometry shows that when the successive sizes of the reamers progressively increase by two millimeters, bone contact and reaming is accomplished . . . [Full Text of this Article]
