Abstract: A slotted slide plate assembly for setting bones in a fracture area and exerting a pressure in a predetermined direction to obtain a bone compression includes a first plate element adapted for a face-to-face engagement with a bone surface; a second plate element adapted for a face-to-face engagement with the topside of the first plate element; a securing device which prevents a relative displacement between the first and second plate elements when they are in a face-to-face engagement with one another; and first and second slide slots provided in the first and second plate elements, respectively, and being oriented parallel to the predetermined direction. The two slide slots are overlapping when the two plate elements engage one another. Each slide slot has sloping slide ramps arranged such that the slide ramp in the first plate element is a continuation of the slide ramp in the second plate element. Thus, a tightening screw inserted through the two slide slots from the topside of the upper, second plate element slides, while being screwed into the bone, with a screw head on the slide ramp provided in the second plate element and subsequently slides on the slide ramp provided in the first plate element.
