ABSTRACT:
A variable angle connection between a spinal rod (A) and a vertebral anchor (B) with a clevis (3) to attach to the vertebral anchor, permitting the vertebral anchor to be longitudinally offset from the connecting point on the rod. The connection assembly has a bolt (2) with an aperture (6) for receiving a portion of the spinal implant rod at one end. The assembly also has a clevis (3). The clevis defines a bore (7) to hold a portion of the vertebral anchor and the ears (8, 9) of the clevis have holes through which the bolt is located with the bolt rotatably connected to the ears. The assembly also has a rod interface washer (4) positioned over a portion of the bolt, between the aperture (6) of the bolt and the inside ear of the clevis. The rod interface washer is partly movable between the aperture of the bolt and the clevis, but the washer is fixed against rotating in relation to the bolt. Finally, the assembly also includes a compression member (5) that pushes the rod toward the vertebral anchor so that the inside and outside ears of said clevis are pressed together and the clevis is tightened the vertebral anchor.
