One embodiment of such implants includes an elongated shaft coated to encourage bony in-growth, having a non-round cross section, and a flange at one end, which is laterally inserted into a preformed insertion path formed in adjacent bone segments traversing a joint or fracture location, to the point where further insertion is blocked by the flange intersecting one of the bone segments. The other end of the shaft may have a portion of male thread protruding out of the insertion path in the second of the bone fragments and adapted to be mated to a fastener having female thread. When the fastener is tightened against the outside of the second bone segment, perhaps using a washer, the joint or fracture is compressed and stabilized resulting in an effective fusion of the joint or fracture when the bone secures itself in the insertion path to the shaft's bony in-growth surfaces on both sides of the joint or fracture line. | 2014-08-07 |
20140222088 | Implant and Fastener Fixation Devices and Delivery Instrumentation - Described here are delivery or fastener device fixation implant devices, delivery instrumentation, and methods for using them. In particular, the description relates to implants having a having a strength sufficient to support, anchor, secure, maintain, or to otherwise repair an elongated delivery or fastener device anywhere such a device, such as, for example, a bone screw, may need further securing within a substrate it is inserted into, such as, for example, within human or animal tissue, such as bone tissue. | 2014-08-07 |
20140222089 | Polyaxial Screw - The present invention generally is directed toward a spinal fixation system whereby a coupling element allows the physician to selectively lock or unlock either the connection between the coupling element and a fastener, such as to allow for repositioning of the coupling element, or the connection between the coupling element and an elongate rod. The locking or unlocking of these connections may be made independently and as desired by the physician. | 2014-08-07 |
