Abstract
A method for reducing a fixation rod is provided. The method minimizes the surgical corridor by performing fixation within the surgical corridor defined by the screw extender. The screw extender is attached to the spinal implant. The method includes the steps of coupling the proximal end of a first cannulated body with the screw extender and rotating a second cannulated body within the first cannulated body. The method proceeds to the step of actuating a rod pusher with a first driving feature so as to engage the rod pusher with the fixation rod. The rod pusher includes a bore. The method proceeds to the step of rotating an inserter shaft within first cannulated body, second cannulated body and bore of the rod pusher, the inserter shaft including a proximal end with a second driving feature and a distal end with a setscrew attachment feature.
