Abstract:
1. An osteosynthesis plate of a single solid piece in a box shape comprising: a plate having a structure with at least 25% of its footprint as open area; the plate having between 2 and 10 apertures for receiving screws; the plate having an upper surface for facing away from bone portions and a lower surface for contacting with the bone portions; the plate having screws that are adapted to be inserted in the apertures to secure the plate to the bone portions; the plate consisting of four truss members; the plate having a structure in which the apertures act as connecting points for the four truss members, the truss members including two parallel truss members which run parallel to one another in a direction along the length of the plate and two diagonal truss members which extend diagonally from four corners of the plate and cross diagonally and intersect at a solid continuous intersection without a screw hole near the centroid of the plate; wherein the diagonal truss members and parallel truss members meet at the four corners of the plate; wherein said intersection is the singular material connecting point on one symmetric line which runs parallel to said parallel truss members in the plane of the plate and said intersection and said parallel truss members are the only structures on a second symmetric line which is oriented normal to the first symmetric line in the plane of the plate; wherein each diagonal truss member extends continuously from one of the four corners of the plate to another of the four corners of the plate along a single, continuous, diagonal truss axis; and wherein the smallest angle formed between the diagonal truss members at the intersection is greater than or equal to forty-five degrees.
