Patent ID: 8491584

Claim:
A device for interconnecting first and second fractured bone segments, the device comprising: a nail made of a material, having a proximal end, a distal end, an outer surface, a proximal shaped bore, an axial bore, and a transverse bore; one or more extendable nail tangs, each extendable nail tang having a first position substantially within the outer surface of the nail, and a second position penetrating the outer surface of the nail; a lag screw for insertion through the transverse bore of the nail, the lag screw having a proximal end, a distal end, and a circumferential outer surface; wherein the circumferential outer surface of the lag screw further comprises anti-rotation flats, where the anti-rotation flats are planar surfaces having an angle with respect to a centerline axis of the lag screw, creating a taper by virtue of the anti-rotation flats near the distal end of the lag screw being a smaller distance apart than the anti-rotation flats near the proximal end of the screw; and one or more extendable lag screw tangs, each extendable lag screw tang having a first position substantially within the circumferential outer surface of the lag screw, and a second position penetrating the circumferential outer surface of the lag screw.
