The main clinical manifestations of cervical spondylosis include pain, numbness and weakness in the upper extremities, which may be accompanied by pain in the back of the shoulder, head and neck. Some patients may have lower limb pain and weakness. Cervical spondylosis is clinically divided into 4 types: 1. spinal cord type The pathogenesis is bony stenosis of the cervical spinal canal or backward protrusion of the intervertebral disc compressing the spinal cord, and this type generally requires surgery. 2, nerve root type disc herniation or spinal stenosis compression of nerve roots, mostly accompanied by nerve root edema and its surrounding soft tissue non-specific inflammation, this type after intervention with physical therapy, lumbar back muscle exercise can be more long-term relief. Those who are not satisfied with conservative treatment can be operated. 3, sympathetic type Cervical instability affects the sympathetic nerve in the neck, mostly manifesting as dizziness, headache, even palpitations, chest tightness and other symptoms, which can be treated conservatively or interventionally, and surgery can be considered in severe cases. 4, vertebral artery type This type is rare, caused by cervical spine lesions compressing the vertebral artery caused by insufficient blood supply to the brain, and mostly take surgery. Bai Zhiyong, Department of Ultrasound, Tsinghua Changgeng Hospital, Beijing Nerve block or radiofrequency treatment can not only quickly relieve the symptoms of cervical spondylosis pain, but also treat soft tissue inflammation, reduce edema and compression of nerve roots, and with physical therapy and rehabilitation training, the patient’s symptoms can be relieved for a long time, and some patients can avoid surgery. Nerve block and radiofrequency treatment are suitable for most neurogenic and sympathetic cervical spondylosis. II. Indications include: 1. Heavy pain, but MRI or CT shows mild cervical spine lesions, and surgery is not required or is not expected to be effective. 2.Patients with multiple diseases or poor physical condition, who cannot tolerate surgery or have high risk of surgery. 3.After cervical spondylosis surgery, the pain is not reduced or recurs. The methods of ultrasound-guided cervical spine interventional therapy mainly include: ultrasound-guided nerve root block, epidural block, superficial cervical follower block, deep cervical follower block, cervical sympathetic nerve block, pulsed radiofrequency treatment of the above-mentioned nerves and their branches, etc. Ultrasound-guided interventional treatment has the advantages of accurate localization, less damage, fewer side effects and clear results.
