Cervical fusion is the gold standard for the treatment of degenerative lower cervical disc disease. In the past, when such surgery was performed, additional steel plates were often required for fixation along with the implantation of the fusion, but the application of steel plates had the following problems and risks: 1. Loosening of the screws led to displacement of the plates; 2. Abrasion of the plates on the esophagus caused esophageal fistula; 3. The plates protruded from the surface of the cervical spine causing a foreign body sensation or difficulty in swallowing; 4. There is also a long operation time and the need to pull the trachea harder during the operation, which increases the chance of laryngeal nerve injury. Zero zero incision cervical anterior interbody fusion system solves many problems of using steel plate fusion, the fusion device is completely in the intervertebral space after the surgery, there is no metal between the vertebral body and esophagus, thus reducing the incidence of dysphagia, and at the same time has the advantages of short operation time and few complications.
