Lumbar Spine Transforaminal Interbody Vertebral Fusion cage goals neurosurgeon videos. 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 hardware provides immediate stability while the bony fusion occurs over the following three to twelve months. 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. Cage struts are used to replace the neurosurgeon videos. 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.
