ABSTRACT:
A connection assembly for connecting a spinal implant rod to a spinal implant bolt includes a rod connecting member having an opening for receiving a portion of the rod, and a bolt connecting member having an opening for receiving a portion of the bolt. The rod connecting member and bolt connecting member are rotatably engaged to one another. At least one interface washer is positioned over and between the rod connecting member and the bolt connecting member. Structure for creating a force between the rod, the rod connecting member, the washer, the bolt, and the bolt connecting member is provided. The interface washer has structure for engaging at least one of the rod and the rod connecting member, and for engaging at least one of the bolt and the bolt connecting member, so as to prevent relative rotation of the rod and the rod connecting member and the bolt and the bolt connecting member when the force is applied.
