Spinal implant device with fixation plates and lag screws and method of implanting

A spinal implant device for use with adjacent spinous processes, the spinous processes including a superior spinous process and an inferior spinous process, the spinal implant device comprising:

• a first fixation plate including a first superior end and a first inferior end, the first superior end including a first screw hole, the first inferior end including a second screw hole, the first fixation plate being sized and configured to extend between and along the spinous processes with the first screw hole adjacent the superior spinous process and the second screw hole adjacent the inferior spinous process;
• a second fixation plate including a second superior end and a second inferior end, the second superior end including a third screw hole, the second inferior end including a fourth screw hole, the second fixation plate being sized and configured to extend between and along the spinous processes with the third screw hole adjacent the superior spinous process and the fourth screw hole adjacent the inferior spinous process;
• a connector connected to the first fixation plate between the first superior end and the first inferior end and to the second fixation plate between the second superior end and the second inferior end;
• a first lag screw sized and configured to extend through the first and third screw holes and threadedly engage a respective one of the first or third screw holes with the superior spinous process disposed between the first and second superior ends;
• and
• a second lag screw sized and configured to extend through the second and fourth screw holes and threadedly engage a respective one of the second or fourth screw holes with the inferior spinous process disposed between the first and second inferior ends.
