Cervical disc replacement, also known as cervical disc arthroplasty, is a fairly new surgical technique that is performed for the treatment of cervical degenerative disc disease or cervical disc herniation.  It is currently recommended as an alternative toanterior cervical discectomy and fusion (ACDF), which entails removing portions of cervical discs through the front (anterior) of the neck and the subsequent fusion of the adjacent vertebrae that were affected by the damaged discs in order to prevent spinal instability.
