A spine fixation assembly connecting a first and second vertebra includes first and second elongated plates that form an X-shaped structure. The first elongated plate has a first and a second end that are attached to a first location of the first vertebra and to a second location of the second vertebra, respectively. The second elongated plate has a first and a second end that are attached to a second location of said first vertebra and to a first location of the second vertebra, respectively. The ends of the plates are attached to the various locations of the vertebra via screws or hooks. The elongated plates may have adjustable length, may be rotated around a central axis passing through the center of-the X-shaped structure and may be cross-coupled to each other via a screw. A third and fourth elongated plated may be attached horizontally across the top and bottom of the X-shaped structure, respectively.
