The mounting plates are connected by an articulated bearing each to a spindle having right-hand and left-hand, self-locking threads with an angular shaft piece for actuating the spindle, wherein the mounting plates have a ribbed area on the side facing the vertebral bone W. The articulated bearing includes a bearing bush extending outwardly from each mounting plate and a bearing pin which has a threaded hole for engaging the spindle. The bushing has a hole allowing the spindle to pass through the bearing bush wherein pin is moveable within the bearing bush.
