Change of the direction of the screw load depending on the alignment of the connecting rods (black) - on the left side the vertical force component corresponds to the perpendicular (F). As the rods are aligned out of the perpendicular (F), the vertical applied load also acts in the horizontal (Fh) and the vertical force component (Fv) decreases; shown in the middle and on the right: pedicles that are more narrowly and more widely spaced
