Abstract: Disclosed is a surgical alignment and distraction frame and associated methods of use that facilitates correction of a sagittal imbalance. The alignment and distraction frame works in conjunction with pedicle screw installation guide assemblies to impart the desired correction. The alignment frame can be utilized to ensure the pedicle screw housings are aligned (to facilitate rod coupling) in concert with the completion of a correction maneuver.

Abstract: This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. Instruments are provided to aid in insertion and positioning or the rod.

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.

Abstract: Systems and methods for a guide assembly for introducing a bone anchor to an operative target site. The guide includes an outer sleeve and an inner sleeve. The outer sleeve has a distal anchor engaging end, a proximal end, and a central passage extending from the distal end to the proximal end. The inner sleeve may be situated in the central passage of the outer sleeve. The inner sleeve is movable being between a first position and a second position. The first position permits insertion of the bone anchor in the central passage. The second position releasably fixes the bone anchor to the guide assembly.
