This procedure isused to remove an intervertebral disc that is causing uncontrollable pain or is compressing the adjacent spinal cord or nerve roots. Bone blocks used to replace the removed disc and maintain correct alignment. Pedicle screw instrumentation is used to ensure stability while fusion occurs.

However, the basic procedure illustrated here is common to all posterior lumbar interbody fusions. Also shown is the patient position, skin preparation and incision, the surgical approach, the removal of the pathological intervertebral disc, the bone block insertion, the pedicle screw fusion instrumentation, x-ray position checks and finally wound closure.
