Anterior cervical discectomy and fusion (ACDF) has been the gold standard for the relief of symptoms associated with cervical degenerative disc disease.

Unlike ACDF, cervical arthroplasty preserves motion at both the index and adjacent disc levels and as such, potentially minimizes adjacent segment degeneration and disease.
