ABSTRACT:
A bone plate arrangement consists of a bone plate (1), at least one bone screw (3) and a cover plate (5, 22, 30, 34, 38) which covers the head (4, 21, 26) of the bone screw and is to be screwed to the bone plate. Devices for fixing the direction of the bone screw (3) relative to the bone plate (1) are provided. These devices consist, on the one hand, of a seat which, though indifferent with respect to direction, laterally fixes the screw head on the bone plate and, on the other hand, of a positive of frictional connection betwen the screw head and the cover plate, produced by mutual engagement of the raises and recesses. The cover plate is laterally fixed relative to the bone plate.
