What is Cervical Disc Replacement?
CDR (cervical disc replacement) is a neck surgery that removes a damaged cushion between the vertebrae and replaces it with an artificial disc made of metal or plastic. The artificial disc helps relieve pressure on pinched nerves or the spinal cord that develops over years of aging and natural wear and tear.
Unlike cervical fusion, which stabilizes the treated vertebrae by allowing them to heal together, cervical disc replacement is designed to preserve motion at the treated level. Whether CDR or a fusion procedure is more appropriate depends on factors such as the condition of the disc and facet joints, spinal alignment, stability, the location of nerve or spinal cord compression, and the patient’s overall anatomy.
