  • Orthopedic fastener device
    Patent number: 9901379
    Abstract: An orthopedic structure includes a method for making a threaded fastener with thread geometry and leading edge geometry which provides greater precision during installation. Specifically, thread pitch and tooth profiles are independently variable. A leading portion of the fastener advances bone shards forward of the forward of the fastener to reduce insertion torque and prevent the shards from residing in the upstream tooth profile for better retention.

  • Medical fastener
    Patent number: 9782209
    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.
