A fastening assembly is provided for fastening a fixing element, for example a plate, a brace, an angle, a profile, an armature, a retainer or the like to a substructure by means of at least one screw, which can be passed through at least one bore in the fixing element and can be screwed into the substructure. A bushing is arranged in the bore to be able to be swiveled in arbitrary spacial direction. The screw is passed through the bushing. The bushing comprises a seat for at least partially receiving a head of the screw.

Fastening assembly

A bone screw has a screw head and a threaded shank. An axial bore into which a plurality of radial bores set at a distance from each other open, extends through the threaded shaft. The axial bore is open at the screw head side end, and the radial bores are also open at the radially outer end. The axial bore is closed in an axial direction in the area of the end of the screw shank that lies opposite the screw head.
