Many controversies still exist with regard to the surgical treatment of cervical spine pathology. The role of allograft, autograft, plate fixation, and bone morphogenetic protein is not entirely clear. There is still debate about the surgical treatment of myelopathy anteriorly as opposed to posteriorly. Clearly, there is substantial anatomic variation in the location of the vertebral artery. Disc arthroplasty for the cervical spine continues to appear to be a viable option for patients with single-level pathology.
