Cervical Anterior Discectomy Interbody Vertebral Fusion neuro-surgeon animations. Shows the goals of a cervical interbody fusion, also known as an anterior cervical discectomy and fusion, which are to stabilize the spine and remove compression of the adjacent spinal cord. This should lead to improved function and less pain. The metal or plastic hardware provides immediate stability while the bony fusion occurs over the following three to twelve months. A cervical interbody fusion is used to remove an intervertebral disc that is causing uncontrollable pain or is compressing the adjacent spinal cord or nerves. A cage is used to replace the excised disc and maintain correct alignment. There are many neuro-surgeon animations to achieve the same end result, an anatomically positioned bony fusion. However, the basic procedure illustrated here is common to all cervical interbody fusions. surgical illustrations. Cervical Anterior Discectomy Interbody Vertebral Fusion neuro-surgeon animations.
