Publication number: 20120089189Abstract: The present invention relates generally to a bone plate for stabilizing bony structures. More particularly, the invention is directed to bone plates having an elongate body to which an integrated rod is formed. Integrated rod portion may be captured by a bone anchor with a receiving member. The bone plate is movable from a first position to a second position and may have an aperture for lagging the bone plate to the bone.Type: ApplicationFiled: October 12, 2011Publication date: April 12, 2012Inventors: Lawrence Binder, Steven Ludwig

Patent number: 8025682Abstract: A rod anchoring system including a bone anchor and a connector is provided. The connector of the rod anchoring system is configured to be inserted in one orientation and then transitioned to a second orientation to connect the rod to the anchor. The bone anchor includes a detachable extension shaft that acts as a guide for inserting the connector. In use, once the bone anchor has been implanted at a target site on a vertebra, the connector is placed onto the extension shaft and slid along its length in a first orientation to insert the connector. Once the connector is at the implant site, it is transitioned from the first orientation to the second orientation to connect the rod to the anchor.Type: GrantFiled: August 31, 2007Date of Patent: September 27, 2011Assignee: DePuy Spine, Inc.Inventors: Michael Mahoney, Christopher L.
