Abstract

An orthopedic screw fastener system, includes at least one screw, consisting in each case of a screw head and of a screw shank, the screw head being provided with a thread, and at least one plate with a thickness, provided with at least one through-bore which is able to receive a screw. The plate has a through-opening, formed by at least two through-bores, each through-bore being defined by a midpoint and by a radius, and the through-bores are offset relative to each other and intersect each other in such a way that intersection lines and/or intersection surfaces form, which extend into the depth of the through-opening.
