The greatest and most important benefit of artificial cervical disc replacement is that the patient’s cervical spine continues to maintain good mobility and flexibility after cervical discectomy. The artificial disc prosthesis not only fills the “gap” between the vertebrae, but also performs the function of a “biological disc” – maintaining cervical flexion/extension, lateral flexion and left/right rotation. Another important benefit of the artificial cervical disc is the protection of the adjacent segment from secondary degeneration, which is the most common complication after cervical fusion, namely premature degeneration of the adjacent segment due to overload. In addition, there are many obvious benefits, including no need for a collar or neck brace, early freedom from bed after surgery, rapid recovery, and early return to normal life and work. The artificial cervical disc mimics the function of a normal human cervical disc. It resembles a shock-absorbing cushion that absorbs shock from the ground, while also rebuilding and maintaining the height of the intervertebral space that has been lost due to pathology, etc. The most important function of the artificial disc is to maintain the movement of the intervertebral joints and to protect the adjacent segments from secondary degeneration. The traditional method of cervical spine surgery is to remove the diseased disc and then place bone graft between the upper and lower vertebrae to fill the space left by the disc removal and to promote complete fusion of the upper and lower vertebrae together for the purpose of radical treatment. However, cervical fusion often leads to premature degeneration called secondary degeneration due to the increased stress on the adjacent segmental discs. The artificial cervical disc protects the adjacent discs from premature degeneration because it maintains the movement of the intervertebral space in the segment. Regarding the indications for artificial disc replacement in the cervical spine, I believe that neurogenic cervical spondylosis is the best. For spinal cord cervical spondylosis, especially in patients with degeneration of the cervical spinal cord, it should be listed as a contraindication. In some cases, the doctor’s inaccurate grasp of the condition, or the patient’s misconceptions that artificial disc replacement in the cervical spine is the best surgical procedure, strongly requesting artificial disc replacement, forcing this procedure when it is not suitable for their condition, will likely result in adverse consequences. Finally, I tell you: money may be a contraindication to certain surgeries and definitely not an indication for surgery.
