| 20080249578 | Fastener for securing two separate workpieces - A locking or fastener system for joining or attaching a first workpiece spaced apart from a second workpiece. A threaded opening is provided in the first workpiece for receiving a screw/collar combination. The screw has a threaded end and a head end. The screw head is rotatingly attached within a cavity within the collar. External threads on the wall of the collar cooperate with the threads in the opening in the first workpiece. When the collar is secured to the first workpiece, the screw may be rotated to engage the second workpiece. By using a wrench having an outer body with extending blades and an inner rod having a screw face, the collar and screw may be tightened to join two spaced-apart workpieces. | 10-09-2008 |

| 20120089197 | ARTHRODESIS IMPLANT APPARATUS AND METHOD - An arthrodesis anchor is formed as a monolithic piece for ease of handling and use, having two ends, one of which has prongs supporting barbs extending radially therefrom. The other end may have threads or barbs. A neck between may circular in cross section and be sized from about 0.045 inches to about 0.08 inches and may be conveniently sized at 0.062 inches for bending to accommodate final alignment of joints to be bonded. Optionally, a shank next to the neck may receive a tool for threading the anchor into a joint. The proximal and intermediate phalangial joints may be trimmed and pilot drilled, after which a first end may be inserted by a tool, typically into the proximal joint by threading or linear insertion of barbed prongs. The second end having barbed prongs may then be inserted into a pilot drilled into the base of the intermediate joint. | 04-12-2012 |
| 20120109222 | Removable Anchoring Pedicle Screw - A removable anchoring pedicle screw includes an implant mounting screw, an anchor screw, and a nose piece. The anchor screw is configured to be rotated relative to the implant mounting screw such that the nose piece engages an expandable anchor. The expandable anchor is disposed between the implant mounting screw and the nose piece such that rotation of the anchor screw relative to the implant mounting screw causes expansion of the expandable anchor. | 05-03-2012 |
| 20120116465 | Fixation Assembly Having An Expandable Insert - A fixation assembly having one or more insertions member that include one or more expandable and retractable anchoring inserts positioned along at least a portion of the insertion member and methods of use thereof are disclosed. | 05-10-2012 |
