Ultrasound is the third eye of the physician, with direct visualization of the nerve under ultrasound, direct visualization of the tissue structures surrounding the nerve localization, and direct visualization of the spread of the local anesthetic during injection. Ultrasound-guided injection therapy prevents the therapeutic drug from entering into the blood vessels or nerves. With the help of ultrasound, the physician changes from the traditional blind probing operation to a visual operation. Because visualization allows direct injection around the nerve, ultrasound-guided nerve blocks are more effective and longer lasting, improving the effectiveness of the block. Ultrasound-guided injection therapy optimizes traditional operations and even performs operations that cannot be performed traditionally. Therefore, ultrasound has opened up a new field for the treatment of painful diseases. Cervical spondylosis, also known as cervical spine syndrome, is a general term for cervical osteoarthritis, proliferative cervicitis, cervical nerve root syndrome and cervical disc prolapse, which is a disorder based on degenerative pathological changes, mainly due to long-term cervical spine strain, osteophytes, or disc prolapse and ligament thickening, resulting in a series of clinical syndromes of cervical spinal cord, nerve root or vertebral artery compression and dysfunction. The symptoms of cervical spondylosis are very rich, diverse and complex, and most patients start with mild symptoms and gradually aggravate them later; there are also some people with heavy symptoms, often with one type mainly combined with several other types together, called mixed cervical spondylosis. The main symptoms are: 1. neck and shoulder pain can be radiated to the head and occipital region and upper limbs; 2. a feeling of heaviness in the back of one shoulder, weakness in the upper limbs, numbness in the fingers, loss of sensation in the skin of the limbs, weakness in gripping things in the hands, and sometimes unconscious gripping of things to the ground. 3.Often accompanied by head, neck, shoulder, back and arm pain, neck and neck stiffness, limited movement. 4.Some of them are accompanied by dizziness, house rotation, heavy cases with nausea and vomiting, bedridden, a few may have vertigo and sudden collapse. 5.The typical manifestation of its seriousness is: weakness of lower limbs, unstable walking, numbness of two feet, and the feeling of stepping on cotton when walking. 6.The most serious cases even have loss of control of bowels and urine, sexual dysfunction, and even tetraplegia. 7.When cervical spondylosis involves sympathetic nerves, dizziness, headache, blurred vision, swelling of the second eye, dryness, inability to open the second eye, tinnitus, ear blockage, balance disorders, tachycardia, panic, tightness in the chest, and some even have symptoms such as gastrointestinal distention. There are also symptoms such as difficulty in swallowing and pronunciation. Most of the symptoms are mild at the beginning and are not taken seriously, and most of them can recover on their own, sometimes light and sometimes heavy. If the disease is left untreated for a long time, it can cause psychological damage and produce symptoms such as insomnia, irritability, anger, anxiety and depression. The treatment methods for cervical spondylosis can be divided into two categories: non-surgical treatment and surgical treatment. Currently, most medical experts advocate non-surgical treatment for cervical spondylosis, and only a few cases require surgical treatment. In recent years, a new method of “treatment removal” has entered the modern treatment system, that is, anti-inflammatory and analgesic drugs are injected directly into the cervical spine nerve pathogenesis site to eliminate local inflammation and edema, improve microcirculation, and produce the effect of “targeted treatment”. This method can quickly bring the drug into full play locally, reduce and eliminate soft tissue inflammation, and thus relieve or eradicate most cervical spondylosis. The amount of medication used is only one percent or even one thousandth of the dose of oral and intramuscular injections, and this method does not require hospitalization. The patient can go home after a ten-minute break after each treatment, and there is basically no significant impact on the patient’s work and life. The pain department of our hospital uses ultrasound guidance to escort this new treatment method, making it more efficient and safer to use the treatment method with significant efficacy. Warm reminder: After this treatment method quickly and effectively cures cervical spondylosis, patients still need to pay attention to rehabilitation and health care, so that the relevant symptoms can be truly eradicated and never recur.
