Anterior cervical discectomy and fusion (ACDF) is the surgical procedure in where a herniated or degenerative disc is removed from the neck/spine area of the back. The procedure is first approached through the front of the patient with an entry through the throat. After exposure to the injured disc, it is surgically removed from the vertebrae. The nerve stems in the area are then compressed and relieved with the use of bone spurs (osteophytes). Finally, the open space between the two vertebrae are filled in with the use of bone graft or artificial bone filling and completed by being fused together.
