Cervical artificial disc, is a new spinal surgery technology developed in the last 10 years or so. Cervical artificial disc, is the use of medical alloy and polymer polyethylene as an artificial prosthesis, the appearance of the cervical intervertebral disc similar to the tongue-shaped elements, in order to replace the function of the degeneration of the intervertebral disc, so that the lesion of the cervical spine to retain the height of the spinal interspace and restore a certain degree of intervertebral mobility after surgery. Cervical artificial disc replacement surgery is performed through an anterior cervical approach, pushing away the trachea and esophagus, protecting the large blood vessels and nerves, removing the disc tissue from the diseased segment, relieving the compression of the spinal cord and nerve roots, and implanting an artificial disc prosthesis in the location of the original disc. However, the second half of the surgery is completely different. In fusion surgery, a bone block is implanted into the intervertebral space to fill in the “gap”, whereas in cervical artificial disc replacement surgery, an artificial disc prosthesis is implanted into the intervertebral space. Cervical artificial disc replacement surgery allows the patient to maintain good mobility and flexibility in the cervical spine after a cervical discectomy. Secondly, it protects the adjacent segments of the disc from secondary degeneration, which is the most common complication after traditional cervical fusion, i.e., premature degeneration of the adjacent segments of the disc due to overloading, reducing the range of motion of the cervical spine, sometimes forming a pseudojoint, and the neck has to be braked for 3 months after the interbody fusion surgery. Of course, cervical artificial disc replacement, as a new technology, requires strict surgical training and certain clinical experience.
