The intervertebral fusion cage is a large, hollow cylinder made of some type of metal, usually titanium. It is designed as a cage so that bone graft can be placed inside the hollow cylinder to allow a spinal fusion to occur between two vertebrae.
It then continues, along with a contribution from the dura matter, the filum terminale externa, to attach to the coccyx, anchoring the lower end of the spinal cord. The spinal cord is composed of a core of gray matter surrounded by white matter. The white matter appears in three locations: lateral, anterior and posterior to the gray matter (the lateral, ventral and dorsal funiculi, respectively). The white matter consists of tracts that interconnect segments of the spinal cord or connect the spinal cord with the brain. The gray matter appears in a butterfly shape, with ventral and dorsal horns, an intermediate gray matter and, in the thoracic cord, a lateral horn (sympathetic neurons).
