A bendable bone plate (10) is disclosed which is adapted for use in situ as a conformable bone splint to fix the spatial relationship of at least two bone parts (80). The bone plate (10) has an elongated plate (11) made of a bendable material. A plurality of screw apertures (24) extending through the top (14) and bottom (16) surfaces are disposed along the length (L) of the plate. Bone screws (28) are inserted through the apertures into the underlying bone parts (80) to anchor the elongated plate (11) to the bone parts (80). At least two of the screw apertures (24) are disposed as a closely spaced pair (40) of screw apertures (24) with a “bend relief zone” (60) disposed between the closely spaced apart screw apertures (24). The bend relief zone (60) is disposed to allow the elongated plate (11) to be bent across the bend relief zone (60) up to a certain angle (A) without deforming the screw apertures (24) adjacent the bend relief zone (60).

1. A bone plate, comprising: a) an elongated plate having a bone contacting bottom surface, a top surface, and a plate thickness between the bottom and top surfaces;b) a plurality of screw apertures extending through the plate thickness and into which bone screws are insertable;c) at least two of the screw apertures being aligned adjacent to each other along a main axis to thereby provide a complex aperture, i) wherein each of the at least two adjacent screw apertures of the complex aperture has a threaded head seat that provides at least a partially threaded portion, andii) wherein a center-to-center distance between the at least two adjacent screw apertures of the complex aperture is greater than a sum of the largest radii of each of them; andd) a bend relief zone provided as an open area extending to and meeting the upper plate surface and the lower plate surface to thereby provide open communication between the two adjacent screw apertures, i) wherein opposed imaginary secondary axes aligned parallel to the main axis extend through points where the at least two screw apertures meet the open area of the bend relief zone, andii) wherein opposed. portions of a perimeter of the bend relief zone reside on an opposite side of a respective one of the imaginary axes spaced from the main axis. 2. The bone plate of claim 1, wherein the at least two screw apertures of the complex aperture each have a largest aperture radius that extends into the bend relief zone of the complex aperture. 3. The bone plate of claim 1, wherein the bend relief zone permits the bone plate to be controllably bent. 4. The bone plate of claim 1, wherein the bend relief zone permits the bone plate to be bent by an angle (A) across the bend relief zone without deforming the screw apertures comprising the complex aperture adjacent to the bend relief zone. 5. The bone plate of claim l, wherein the bend relief zone extends at least half way through a width of the elongated plate, the width being measured perpendicular to the main axis of the complex aperture. 6. The bone plate of claim 1, wherein the bend relief zone has a shape selected from the group consisting of: an oblong shaped relief and a slot shaped relief. 7. The bone plate of claim 6, wherein the bend relief zone is a slot transverse to the main axis of the complex aperture. 8. An orthopedic kit comprising: a) a compartmented container having compartment spaces for receiving items to be contained in the kit;b) a first item of the kit being at least one bone plate of claim 1; andc) a second item of the kit being a plurality of bone screws. 9. The bone plate of claim 1 wherein the perimeter of the bend relief zone is a radiused surface on the opposite sides of the respective imaginary axes. 10. The bone plate of claim 1 wherein the perimeter of the bend relief zone is a squared-off slot on the opposite sides of the respective imaginary axes. 11. The bone plate of claim 1 wherein bend relief zone permits the bone plate to be bent to an angle (A) without deforming the threaded head seat of the screw apertures adjacent the bend relief zone. 12. A bone plate, comprising: a) an elongated plate having a bone contacting bottom surface, a top surface, and a plate thickness between the bottom and top surfaces, wherein the plate is made of a bendable material and has a longitudinal axis extending along a length and wherein a width is perpendicular to the length and the longitudinal axis;b) a plurality of screw apertures extending through the top surface to the bottom surface of the plate, each having a threaded head seat that provides at least a partially threaded portion, wherein at least two of the screw apertures are aligned adjacent to each other along the longitudinal axis to thereby provide a complex aperture;c) each screw aperture having a screw axis that is disposed at an acute angle relative to a plane of the bottom surface adjacent to and surrounding the at least two screw apertures comprising the complex aperture; andd) a bend relief zone provided as an open area extending to and meeting with the upper and lower bone plate surfaces to thereby provide open communication between the two adjacent screw apertures, i) wherein opposed imaginary secondary axes aligned parallel to the longitudinal axis extend through points where the at least two screw apertures meet the open area of the bend relief zone, andii) wherein opposed portions of a perimeter of the bend relief zone reside on an opposite side of a respective one of the imaginary axes spaced from the main axis. 13. The bone plate of claim 12 wherein the perimeter of the bend relief zone is a radiused surface on the opposite sides of the respective imaginary axes. 14. The bone plate of claim 12 wherein the perimeter of the bend relief zone is a squared-off slot on the opposite sides of the respective imaginary axes. 15. The bone plate of claim 12 wherein bend relief zone permits the bone plate to be bent to an angle (A) without deforming the threaded head seat of the screw apertures adjacent the bend relief zone. 16. A bone plate, comprising: a) an elongated plate having a bone contacting bottom surface, a top surface, and a plate thickness between the bottom and top surfaces;b) a plurality of screw apertures extending through the plate thickness and into which bone screws are insertable;c) at least two of the screw apertures being aligned adjacent to each other along a main axis to thereby provide a complex aperture, i) wherein each of the at least two adjacent screw apertures of the complex aperture has a head seat that is a threaded head-seat or an unthreaded head-seat, andii) wherein a center-to-center distance between the at least two adjacent screw apertures of the complex aperture is greater than a sum of the largest radii of each of the respective screw apertures; andd) a bend relief zone provided as an open area extending to and meeting with the upper and lower bone plate surfaces to thereby provide open communication between the two adjacent screw apertures, i) wherein opposed imaginary secondary axes aligned parallel to the main axis extend through points where the at least two screw apertures meet the open area of the bend relief zone, andii) wherein opposed portions of a perimeter of the bend relief zone reside on an opposite side of a respective one of the imaginary axes spaced from the main axis.
