Bone plate
First Claim
1. A bone plate for use in stabilizing a bone having a fracture site, the bone being reduced by a pair of external fixation rods secured to the bone on either side of the fracture site, said bone plate comprising:
- a longitudinally extending axis;
first and second end portions longitudinally spaced from one another;
an intermediate portion extending between and interconnecting said first and second end portions, said first and second end portions and said intermediate portion combining to define an upper surface, a lower surface for application to the bone, and an edge extending between said upper surface and said lower surface, said edge comprising a perimeter of said bone plate;
at least one interior hole formed in said intermediate portion for receiving a bone screw, said at least one interior hole extending through said plate from said upper surface to said lower surface, said at least one interior hole being spaced apart from said edge; and
a plurality of apertures formed in said plate, each said aperture extending through said plate from said upper surface to said lower surface, each said aperture extending to and through said edge whereby said aperture may be temporarily positioned around one of the external fixation rods, at a position proximate the bone, by moving said plate relative to said rod, said aperture being effective for receiving a bone screw after the rod is removed from the bone;
whereinsaid first end portion includes at least one of said apertures;
said second end portion includes at least one of said apertures;
at least one of said apertures formed in said plate extends transversely to said axis, to and through said edge.

Abstract
A bone plate for use in stabilizing a fractured bone is provided having first and second end portions longitudinally spaced from one another and an intermediate portion extending between and interconnecting the end portions. The end portions and intermediate portion combine to define an upper surface, a lower surface for application to a bone, and an edge extending between the upper and lower surfaces. The plate includes at least one interior hole formed in the intermediate portion for receiving a fastener such as a bone screw to attach the plate to the fractured bone. A plurality of apertures are formed in the plate, with each of the end portions including at least one of the apertures which extend through the plate from the upper surface to the lower surface for receiving a bone screw. Each aperture also extends to and through the edge of the plate whereby each aperture may be temporarily positioned around an external fixation rod temporarily secured to the bone, which facilitates positioning the bone plate. Fasteners may be inserted through the apertures to further secure the plate after the rods have been removed. The plate may have a variety of shapes including rectangular, L-shape, Y-shape and others. Depending upon the size of the apertures formed in the end portions, washers may be used in conjunction with the apertures in the end portions to receive bone screws.

30. A bone plate assembly for use in stabilizing a fractured bone, said bone plate assembly comprising:
-
a bone plate; and a pair of washers, each of said washers including an interior aperture and being in contacting engagement with said bone plate; wherein said bone plate comprises; first and second end portions longitudinally spaced from one another; an intermediate portion extending between and interconnecting said first and second end portions, said first and second end portions and said intermediate portion combining to define an upper surface, a lower surface for application to the bone, and an edge extending between said upper surface and said lower surface, said edge comprising a perimeter of said bone plate; at least one interior hole formed in said intermediate portion for receiving a plurality of bone screws to secure said plate to the bone, said interior holes extending through said plate from said upper surface to said lower surface, said interior holes being spaced apart from said edge; and a plurality of apertures formed in said plate, each said aperture extending through said plate from said upper surface to said lower surface for receiving a bone screw, each said aperture extending to and through said edge, each of said first and second end portions including at least one of said apertures; wherein each of said washers is disposed in contacting engagement with said upper surface of said bone plate; wherein said interior aperture of one of said washers is aligned with a first one of said apertures and said interior aperture of the other of said washers is aligned with a second one of said apertures, said first and second apertures being formed in said first end portion and said second end portion, respectively. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
