Abstract
An interference screw is provided by machining a fragment of autograft, allograft or xenograft cortical bone from a donor or from a recipient's amputated bone. The interference screw has a cortical surface into which a self-tapping thread is machined. The interference screw has a machined pointed, rounded or flush end and an opposite machined end which mates with a drive means, and has advantages over conventional interference screws known in the art in that subsequent to implantation, no residual hardware that must later be removed remains at the implant site.
