    摘要: An intervertebral implant (1), having an upper section (10) provided with a ventral side area (11), a dorsal side area (12), two lateral side areas (13,14), a top apposition surface (15) and a bottom surface (16); and a lower section (20) provided with a ventral side area (21), a dorsal side area (22), two lateral side areas (23,24), a bottom apposition surface (25) and a top surface (26). The two sections (10;20) are moveable in relation to each other by means of two joints (38;39) arranged between the two sections (10;20), the two joints (38;39) are realised by an upper joint section (31) connected to the upper section (10), a central joint section (32) and a joint section (33) connected with the lower section (20). One of the external joint sections (31;33) comprises at least one concave sliding surface (58) rotation-symmetrical with regard to a swivel axle (3;4); and the other of the external joint sections (31;33) comprises at least one convex sliding surface (55) rotation-symmetrical with regard to the other swivel axle (3;4).

    摘要: An improved spinal fusion system (10) for positioning between a first and second vertebral body, the system (10) has a body (100), a pair of polyaxial fasteners (220) and a locking bridge (102). The distal end has a slotted opening (120) extending through the body (100) and forming a gap extending between the two or more bore holes (110) to form a deflectable bridge (102) spanning the bore holes (110). The bridge (102) has a center opening (50) for receiving a set screw (20) passing through the bridge (102) into a threaded opening (52) in the body. When the set screw (20) is tightened, it deflects the bridge (102) closing the gap as the bridge (102) contacts an exterior surface of each head (210) of the polyaxial fasteners (200). The angulation of each polyaxial screw (200) is adjustable, controlled by the tightening of the set screw. Initial contact of the bridge (102) with the head (210) of the fastener (200) reduces angulation movement of the shank (220) requiring manual manipulation. Increased tightening of the set screw (20) fixes the angulation as the bridge (102) reduces the gap and increases fastener head contact forces.
