A fusion cage 10 includes a cage body defining an internal cavity with an inner surface and an outer surface. The outer surface defines a helical thread 12 comprised of a plurality of turns which define valleys 14 therebetween. Located in the valleys 14 are perforations 13 which provide communication between the outer surface and the interior cavity. Thus, when the fusion cage 10 is mated to a bone structure and the internnal cavity is packed with bone chips or other bone-growth-inducing substances, there is immediate contact between the bone structure and the bone chips through the perforations 13.
