Lumbar Spine Transforaminal Interbody Vertebral Fusion bone goals neuro-surgeon multimedia. Shows the goals of a lumbar interbody fusion, which are to remove the damaged, painful intervertebral disc and replace it with bone. This eventually fuses the two vertebral bodies together into one solid bone. This should lead to improved function and less pain. The metal or plastic hardware provides immediate neuro-surgeon multimedia. A transforaminal lumbar interbody fusion is used to remove an intervertebral disc that is causing uncontrollable pain or is compressing the adjacent spinal cord or nerve roots. Bone blocks are used to replace the removed disc and maintain correct alignment. 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.
