The traditional treatment methods for cervical spondylosis include anterior fusion after removal of the diseased disc and posterior canal enlargement to relieve pressure on the spinal cord and nerve roots, although the immediate and long-term results are good, some patients still have limited cervical movement and accelerated degeneration of the adjacent segment gap due to fusion. Artificial cervical disc replacement mimics the physiological characteristics of the human intervertebral disc, removing the diseased disc while maximizing the preservation of the segment’s motion. This technology has been carried out abroad for nearly 10 years, while it has only been carried out in China for 3-4 years, and is only carried out in a few large hospitals. Our department launched this technology in May this year, and has successfully completed more than 10 cases of surgery. What kind of patients are suitable for artificial cervical disc replacement? At present, we have the following indications: 1, the causative factor of cervical spondylosis is mainly disc herniation and there is no obvious intervertebral instability; 2, there is no serious osteoporosis and the operated segment does not exceed two gaps. The advantages are: 1. maximum preservation of cervical spine function; 2. effective avoidance or delay of cervical disc degeneration in adjacent segments after cervical fusion; 3. less traumatic surgery and faster postoperative recovery.
