Cervical spondylosis is a common and frequent disease among middle-aged and elderly people, and the age of onset is getting younger and younger. The symptoms are complex and varied, manifesting as neck pain, stiffness, restricted movement, neck and shoulder pain radiating to the upper limbs, finger numbness, dizziness, tinnitus, memory loss, and unstable walking in severe cases. Generally, it can be divided into cervical type, nerve root type, vertebral artery type, spinal cord type and other types. The spinal cord type cervical spondylosis is caused by the protrusion of intervertebral discs, together with the formation of bone superfluity in the cervical vertebrae and small joints, as well as hypertrophy of the ligamentum flavum, which compresses the cervical spinal cord and can cause symptoms of paralysis below the neck. If the symptoms are mild, non-surgical treatment such as traction, physiotherapy, acupuncture, medication and plasters can be given, while paying attention to observation. If the symptoms are obvious and paralysis occurs, surgery must be performed as soon as possible. Otherwise, it will be difficult to recover from the degeneration of the compressed nerve after a long time. In recent years, based on the original cervical discectomy, a new surgical treatment method called low-temperature plasma radiofrequency ablation has been invented abroad. This method was first applied to the treatment of lumbar disc herniation, and it has become increasingly important because of its small trauma and satisfactory effect, replacing lumbar discectomy to some extent. In recent years, this new technique has been gradually applied to cervical spine surgery. Although the structure of the neck is complex, with important organs such as the cervical artery, vein, trachea and esophagus in front, and the cervical spinal cord in the spinal canal is very delicate, the location of the surgical area is superficial and facilitates the operation, which has been successful. Through X-ray fluoroscopic positioning, the surgical vertebral space is determined, and after local anesthesia, under X-ray fluoroscopic supervision, a puncture trocar needle with a core is directly punctured through the skin into the anterior surface of the cervical disc, avoiding important structures such as the carotid artery. The radiofrequency electrode, like an acupuncture needle, is inserted into the intervertebral space, and the herniated disc tissue is vaporized through the effect of low-temperature ablation, thus relieving the compression of the disc on the nerve root and achieving the treatment purpose. Percutaneous puncture radiofrequency ablation has more prominent therapeutic effect than other non-surgical treatment methods such as traction, massage, acupuncture and internal and external medicine. Compared with conventional resection surgery, it is less traumatic, less painful and faster recovery. Since the vertebrae and posterior longitudinal ligaments are not destroyed, the cervical spine stability is maintained to the maximum extent. It is generally believed that if there are symptoms of cervical spondylosis such as neck and shoulder pain, hand numbness and weakness, and cervical disc herniation is shown by MRI or CT examination, but there is no obvious degeneration of the intervertebral disc and the effect of non-surgical treatment is not good, percutaneous puncture radiofrequency ablation can be considered. In early stage of lesion, the disease is mild and the effect is better; in late stage of lesion, the disease is more serious and the effect is worse. Cervical disc prolapse into the spinal canal, cervical spinal canal bony stenosis, etc., compression of the spinal cord degeneration, is not suitable for this method.
