Abstract
This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. A fixation anchor is provided that includes a break off extension guide that extends from an anchor housing which captures a fixation rod. The extension guide has a guide channel that aligns with a rod channel in the housing to help direct the rod into the housing. The extension guide includes proximal breakable joints that allow the arms of the extension guide to be separated to facilitate rod insertion. Distal breakable joints are provided to allow the arms of the extension guide to be removed. Features and instruments for reducing the rod through the extension guide are also provided.
