Patent ID: 7905883

Claim:
A bone plate, comprising: a) a first flange lying in a first plane, the first flange having a first thickness extending from a top first flange surface to a bottom first flange surface with at least one threaded hole formed through the first thickness, wherein the first flange has a first longitudinal axis; b) a second flange lying in a second plane, the second flange having a second. thickness extending from a top second flange surface to a bottom second flange surface with at least one threaded hole formed through the second thickness, wherein the second flange has a second longitudinal axis; c) a web connecting the first flange lying in the first plane to the second flange lying in the second plane, wherein the first plane is at an angle of rotation with respect to the second plane; d) wherein the first longitudinal axis of the first flange is laterally offset with respect to the second longitudinal axis of the second flange; and e) wherein at least one of the threaded holes in either the first flange or the second flange is an overlapping threaded hole comprising an upper portion extending from an oval shaped opening at either the top first flange surface or the top second flange surface part way through the respective first thickness or the second thickness to a threaded lower portion having an hourglass shape extending from where the upper portion ends at the hourglass shape to the bottom first flange surface or the bottom second flange surface with overlapping threaded surfaces of the overlapping threaded hole forming the hourglass shape, the threaded lower portion being adapted to lock with threads of a corresponding bone screw in either one or the other of the overlapping threaded surfaces of the at least one overlapping threaded hole.
