1. A bone plating system configured to be implanted to stabilize a peri-articular fracture of a human long bone, the bone plating system comprising:
(a) a bone plate, configured and dimensioned to be attached so as to be compressed against the long bone and to extend over the peri-articular fracture, the bone plate comprising: a lower surface and an upper surface opposite the lower surface; a shaft portion having a width, the lower surface of the bone plate at the shaft portion configured and dimensioned to conform to a length of a diaphysis of the long bone, the shaft portion including a plurality of bone screw holes having an internal thread; and a head portion that is configured and dimensioned to conform to a metaphysis of the long bone, wherein the head portion flares outward from the shaft portion so as to have a width that is greater than the width of the shaft portion and which curves upward from the shaft portion, and the head portion comprises at least three bone screw holes each conically tapering in the direction from the upper surface to the lower surface and each having an inner surface and a circumference; wherein each of the bone screw holes of the head portion has a thread that extends continuously around the circumference of the inner surface of the bone screw hole and extends continuously from the upper surface to the lower surface; (b) a plurality of locking bone screws each having a threaded shaft configured to engage the long bone and a threaded, conically-tapered head configured to mate with the thread of the inner surface of the bone screw holes of the head portion; and (c) a plurality of non-locking bone screws each having a threaded shaft configured to engage the long bone and an unthreaded, conically-tapered head configured to compress the bone plate to the long bone. |
