Abstract
An improved spinal fusion system () for positioning between a first and second vertebral body, the system () has a body (), a pair of polyaxial fasteners () and a locking bridge (). The distal end has a slotted opening () extending through the body () and forming a gap extending between the two or more bore holes () to form a deflectable bridge () spanning the bore holes (). The bridge () has a center opening () for receiving a set screw () passing through the bridge () into a threaded opening () in the body. When the set screw () is tightened, it deflects the bridge () closing the gap as the bridge () contacts an exterior surface of each head () of the polyaxial fasteners (). The angulation of each polyaxial screw () is adjustable, controlled by the tightening of the set screw. Initial contact of the bridge () with the head () of the fastener () reduces angulation movement of the shank () requiring manual manipulation. Increased tightening of the set screw () fixes the angulation as the bridge () reduces the gap and increases fastener head contact forces.
