A spinal fixation system that includes at least two pedicle screws and a connector plate attached to each pedicle screw with a locking nut at a first end.

The pedicle screw including a cup shaped member that conforms to a lower mating surface on the connector plate and the locking nut having a mating surface with the upper surface of the connector plates to provide a polyaxial connection between the pedicle screw and the connector plate. The rod connector, connecting plate, and, rod connector locking nuts having mating surfaces that allow polyaxial motion between the rod connector member and the connector plate. The spinal fixation system provides a low profile system that is more easily implanted and adjustable so as to reduce the stress to the spinal column and trauma to the surgical incision.
