The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge. ## Claims ### Claim at position 1 -20. (canceled) ### Claim 21 A surgical plate system comprising a pre-contoured Y-shaped plate that has an inferior surface and which has a concentric superior surface, the plate consisting of a trunk and a pair of a first arm and a second arm, the trunk having a medial line along the superior surface extending between a first and a second end, and the inferior surface of the plate defining a curve transverse to the medial line, the trunk including at least one screw hole and, the first arm and the second arm extending from the first end of the trunk, the inferior surface of the first arm and of the second arm spiraling around the medial line of the trunk, the first arm having an ear with at least one screw hole defining a first screw hole axis perpendicular to a tangent to the top surface of the first ear, the first ear being attached to the trunk by a linking section having a waist, a first angle being defined by an intersection of the medial line of the trunk with a first arm linear medial axis, and a first length being defined by a line from a center of the first arm screw hole along the first arm linear medial axis to the medial longitudinal axis of the trunk, and, the second arm having a second ear with at least one second screw hole defining a second screw hole axis perpendicular to a tangent to the top surface of the second ear, the second ear being attached to the trunk by a linking section having a waist, a second angle being defined by an intersection of the medial line of the trunk with a second arm linear medial axis, and a second length being defined by a line from a center of the second arm screw hole along the second arm linear medial axis to the medial line of the trunk, and wherein the waist of the linking section of the first arm and of the second arm is configured to bend relative to the trunk section in response to a force applied before or during surgery without deforming the screw hole and the first angle and the first length being different from the second angle and the second length whereby the first screw hole axis and the second screw hole axis converge toward each other on the inferior side of the plate but do not intersect to allow for multiplanar fixation. ### Claim 22 (depends on 21) The orthopedic plate system as set forth in claim 21, comprising at least two screws, each having a screw axis and wherein each of the first screw hole and the second screw hole includes one of the screws, and the screw axes of the two screws do not impinge on each other. ### Claim 23 (depends on 22) The orthopedic plate system as set forth in claim 22, comprising at least two screws, each having a length and a diameter and wherein each arm screw hole includes one of the two screws wherein the length and diameter of the two screws are such that the two screws do not impinge on each other. ### Claim 24 (depends on 23) The surgical plate system as set forth in claim 23, wherein the medial line of the trunk defines a larger curve in the longitudinal direction than in the transverse direction. ### Claim 25 (depends on 24) The surgical plate system as set forth in claim 24, wherein the larger curve forms a portion of a fishtail shaped curve. ### Claim 26 (depends on 25) A surgical plate system as set forth in claim 25, wherein the trunk has a through hole. ### Claim 27 (depends on 26) The surgical plate system as set forth in claim 26, wherein the trunk has at least two through holes and a waist area between the through holes which encourages bending of the waist area in response to a force applied before or during surgery. ### Claim 28 (depends on 27) The surgical plate system as set forth in claim 27, wherein the trunk has an oblong slot. ### Claim 29 (depends on 22) The surgical plate system as set forth in claim 22, further including at least one screw having a threaded shaft and a head wherein at least one screw hole and the screw head have a mating interface such that the screw can engage the screw hole so as to allow a plurality of angular orientations of the screw axis relative to the screw hole axis. ### Claim 30 (depends on 22) The surgical plate system as set forth in claim 22, further including at least one screw having a threaded shaft and a head wherein at least one screw hole and the screw head have a mating interface such that the screw can engage the screw hole at a locked angular orientation of a screw axis relative to the screw hole axis. ### Claim 31 (depends on 30) A surgical plate system as set forth in claim 30, wherein the screw hole include internal threads and the screw head includes corresponding external threads which mate to fix the orientation of the screw in the screw hole. ### Claim 32 (depends on 31) The surgical plate system as set forth in claim 31, further including a drill guide and the screw hole includes guide keyways which orient the angle of the drill guide relative to the plate.
