Abstract
A method and assembly is provided for linking an additional vertebral construct to an existing spinal construct having at least two bone screws engaged to corresponding vertebrae and connected by a connecting member. The assembly includes a fastener configured to engage a bone screw of the existing construct and to engage a connecting member connected to the bone screw. The assembly further includes a linking member having an elongated portion configured to connect to a bone screw of the additional construct and a mounting structure configured for mounting on the bone screw of the existing construct. A locking member fixes the orientation of the linking member relative to the bone screw and a clamping member locks the linking member and existing connecting member to the bone screw of the existing construct.
