    摘要： The invention comprises an implant having a first end section and a second end section, where the first end has a cancellous thread for implantation in a first section of bone and the second end includes expansion slots and barbs or wings, that that resist movement out of a second section of bone. These anchors expand outwardly when a rigid wire, such as a k-wire is fed through a central cannulation in the implant and either the wire expands in diameter or the cannulation decreases in diameter. The implant also includes a collar intermediate to the first and second section which includes one or more surfaces to allow the first section to be screwed into a first bone section.

    摘要： A cannulated compression screw is used as an orthopedic implant and has a threaded distal end with an insertion tip that includes at least one and preferably two, three or four flutes to allow the screw to be self-tapping. Optionally, the screw also includes one or more reverse cutting flutes proximal to the insertion tip. The distal threads are cancellous threads having a generally constant minor diameter and a generally constant major diameter and a generally constant thread pitch. An intermediate portion of the screw is non-threaded and the proximal end includes a compression wedge or taper that has at least one, and preferably two to five flutes that terminate before the top of the screw. The proximal end further includes a radiused bevel to the terminal surface that includes a hexagonal torque driving recess. The diameter of the non-threaded shaft section is constant distal from the compression wedge to the distal tip where it defines the minor diameter of the threaded portion. The screw optionally includes a tapered insertion tip.

    摘要： A locking mechanism assembly to allow locking of a fastener in an orthopedic implant having its axis at a variable angle relative to the axis of a threaded through opening in the implant. The assembly includes a convexly rounded ring shaped locking insert which mates with the through opening. The head of the fastener includes a concentric flange that engages the locking ring into a locking relationship with the threads of the opening as the fastener is tightened into position. Preferably the locking ring is integral with the head of the fastener. The locking ring is made from a material that is more deformable than the material of the plate.

    摘要： A partially threaded compression wire with a trocar insertion point is inserted into a first bone fragment and a mating button is crimped into position on the wire to cause compression between the first bone fragment and a second bone fragment. A cannulated instrument applies tension to the wire and crimps the button. In a second embodiment, the wire further includes an internally threaded screw or helix. In the related method, the threaded wire is implanted ante grade or retrograde into the first bone segment and a button is crimped to the wire to apply compression to a second bone segment either cutaneously or percutaneously.
