http://www.medilaw.tv Lumbar Spine Pedicle Screw Fixation Fusion lawyer 3D animations. Illustrates the surgical technique for performing a laminectomy and pedicle screw fusion. This procedure is used to decompress the spinal cord and immobilize an intervertebral disc or facet joints that are causing uncontrollable pain. Pedicle screw instrumentation is used to ensure stability while fusion occurs. There are many different techniques to achieve the same end result, a pain-free, stable, anatomically positioned bony fusion. However, the basic procedure illustrated here is common to all pedicle screw fusions. Also shown is the patient position, skin preparation and incision, the surgical approach, the removal of the lamina, the insertion of the pedicle screws, rods and bone graft, x-ray position checks and finally wound closure.
