Patent ID: 7722653

Claim:
A bone plate, comprising: a) a head portion; b) an elongated lower portion extending from the head portion, wherein the bone plate comprising the head portion and the elongated lower portion comprises a bone-contacting bottom side and a top side; c) a first complex aperture located in the elongated lower portion, the first complex aperture comprised of two overlapping holes having an offset of a given distance between centers thereof, wherein the two overlapping holes of the first complex aperture extend along a first longitudinal axis and comprise a compression ramp extending from a first oval shaped opening at the top side of the plate downwardly and inwardly part way through the plate thickness to a threaded lower portion having an hourglass shape extending from where the upper portion ends at the hourglass shape to the bottom side of the bone plate with threaded surfaces of the overlapping holes meeting each other at a threaded overlap forming the hourglass shape, the lower portion being adapted to lock with threads of a corresponding bone screw in either one or the other of the overlapping holes, wherein the first longitudinal axis bisects the first oval shaped opening along a greatest length thereof; d) a second complex aperture located in the head portion, the second complex aperture comprised of two overlapping holes having an offset of a given distance between centers thereof, wherein the two overlapping holes of the second complex aperture extend along a second longitudinal axis and comprise a compression ramp extending from a second oval shaped opening at the top side of the plate downwardly and inwardly partway through the plate thickness to a threaded lower portion having an hourglass shape extending from where the upper portion ends at the hourglass shape to the bottom side of the bone plate with threaded surfaces of the overlapping holes meeting each other at a threaded overlap forming the hourglass shape, the lower portion being adapted to lock with threads of a corresponding bone screw in either one or the other of the overlapping holes, wherein the second longitudinal axis bisects the second oval shaped opening along a greatest length thereof; and e) wherein the first and second longitudinal axes of the respective first and second complex apertures are angled with respect to each other.
