  • Patent number: 6706045
    Abstract: The present invention is directed to one piece connector for connecting angularly misaligned implanted pedicle screws to transverse spinal rods in spinal fixation systems. The body portion includes a bore having an inside diameter and a longitudinal axis, with the longitudinal axis of the bore being positioned perpendicular to the longitudinal axis of the leg portion. The leg portion includes a slot placed through a section of the leg portion, along the transverse axis of the leg portion and parallel to the longitudinal axis of the leg portion. The slot intersects the bore of the body portion perpendicular to the longitudinal axis of the bore. The slot allows the one piece connector to be securely clamped around a longitudinal spinal rod when a pedicle screw is implanted at variable distances from the longitudinal spinal rod.
