Abstract: A bone fusion assembly includes a bone plate having a plurality of through openings extending therethrough. The through openings include at least one fusion screw opening sized to allow a screw guide to be at least partially inserted therein and a plurality of fixation screw through openings. The screw guide includes a body having a proximal end, a distal end, and a through-passage extending between the proximal end and the distal end. A K-wire a sized to extend through the through-passage in the body of the screw guide.

Abstract: Devices and methods are provided for surgical retraction with a minimally invasive, maximum access surgical system. The surgical system can include anchor extensions that can be attached to bone screws. The bone screws can be inserted into a pedicle of a vertebral body. A retractor can be attached to anchor extensions connected to adjacent vertebrae on an operational side, and the retractor can be attached to anchor extensions connected to adjacent vertebrae on a contralateral side. The retractor can be used to distract the vertebral disc space between the adjacent vertebrae.
