Claim 0:
1. A bone plate assembly for the compression of a bone fracture or osteotomy, comprising:
a plate body having a longitudinal axis, a distal end defined by a widest portion of the plate body and extending to a narrower proximal end, an upper surface, a lower bone contacting surface, a plurality of first screw holes arranged in rows at the distal end of the plate body, a second screw hole at the proximal end of the plate body, an access hole between the first and second screw holes, and an adjustable third screw hole extending through the plate body between the access hole and second screw hole, the plate body further comprising a recessed portion in the upper surface surrounding an opening through the plate body defining the adjustable third screw hole,
wherein the access hole is an orientation indicator extending between the upper surface and the lower, bone contacting surface, the access hole having a shape to indicate an anatomical orientation of the bone plate assembly, which anatomical orientation is either a right side or a left side of the patient,
wherein the second screw hole has a main chamber and a narrow portion, the narrow portion being connected to the main chamber in a smooth transition to form a continuous curved opening in the shape of a teardrop, the main chamber defined by a wall having threads while the narrow portion is non-threaded and includes a compression notch; and
wherein the bone plate assembly further comprises a bone screw comprising a head extending into an elongated threaded shank, the head having an outer surface and the elongated threaded shank having a diameter, the bone screw being configured for insertion into the opening of the adjustable third screw hole,
wherein the opening of the adjustable third screw hole is smaller than the outer surface of the head and larger than the diameter of the elongated shank, and
wherein the recessed portion in the upper surface has an inner surface defining an opening in the upper surface of the bone plate, wherein the inner surface of the recessed portion is sized to define a gap around the opening of the adjustable third screw hole and substantially around the entire outer surface of the head of the bone screw to allow for movement of the bone screw within the recessed portion along the longitudinal axis and in at least one direction transverse to the longitudinal axis of the plate body.
