Abstract
A bone plate is described which is adapted for use in situ to fix a spatial relationship of at least two bone parts. The bone plate has at least one pair of the bone screw apertures that are adjoined by a relief-space contiguous with the open space of the screw apertures themselves. An adjoined aperture pair forms a complex aperture and has a center-to-center distance d of the apertures along an axis running through the centers of the apertures. The center-to-center distance d is equal to or greater than the sum of the radii (r1+r2) of the heads of the individual bone screw used with the aperture pair.
