Patent abstract
A dual-start fastener is disclosed having two threads helically wound about its shaft. The thread tooth profile (in section) constitutes substantially parallel upper and lower facets on each thread flank. A first thread has a crest diameter greater than a second thread. A distal end of the fastener includes self-tapping cutters formed on the threads which force shards of bone to advance into shallow troughs adjacent the cutters for subsequent resorption by adjacent osseous tissue.
