Abstract
With the invention the connection of a bone screw (12) to a bone plate (7) is shown. The head (13) of the bone screw (12) lies with a ring-shaped outer surface (10) in contact on a counter-surface (25) and can be fixed with a securing screw (15) which can be screwed in in the direction towards the counter-surface (25). In this the height (16) of the bone plate (7) is chosen such that it is less than or equal to the shaft diameter (19) of the bone screw (12), whereas the screw head (13) dips into a cut-out (20) of the securing screw (15) and the upper side of the securing screw (15) terminates with the upper side of the bone plate (7).
