Abstract
A spinal fixation system. The spinal fixation system has a set of screw clamp assemblies adapted for attachment of a rod. The spinal fixation system comprises anchor screws and clamps. The anchor screws include a shoulder width 'y' that varies within the anchor screws in the set to seat a clamp at a desired distance above the plane of the spine into which the anchor screws are implanted. The clamps include an arm length 'x' that varies within the clamps in the set to attach the rod at a desired distance from the clamp seat site and apertures for receiving the rod within the clamps, wherein the apertures are set at an angle 'a' from a plane perpendicular to the long axis of the anchor screw when a clamp is seated on the anchor screw that varies within the clamps in the set.
