ABSTRACT:
A connection assembly for connecting a spinal implant rod to a spinal implant bolt includes a rod connecting member having an aperture for receiving a portion of the rod and a bolt connecting member having an aperture for receiving a portion of the bolt. The rod connecting member and bolt connecting member are rotatably engaged to one another. A rod interface washer is positioned over a portion of the rod connecting member, and a bolt interface washer is positioned over a portion of the bolt connecting member. The rod interface washer and bolt interface washer are moveable in part between the rod connecting member and the bolt connecting member, the rod connecting washer being fixed against rotation relative to the rod connecting member and the bolt interface washer being fixed against rotation relative to the bolt interface washer. Structure extendable into at least one of the apertures is provided, so as to urge one of the rod and bolt toward the other, and to cause the washers to be pressed together between the rod and the bolt, preventing rotation of the rod interface washer and rod connecting member relative to the bolt interface washer and bolt connecting member, and securing the rod to the bolt.
