1. Cervical disc herniation is a condition in which the spinal cord and nerve roots are compressed due to the herniation of the intervertebral disc on the basis of degeneration of the intervertebral discs caused by a slight external force or without a clear incentive, resulting in the corresponding symptoms. 2. Types and clinical manifestations ①. Lateral cervical disc herniation The herniated part is on the lateral side of the posterior longitudinal ligament and the medial side of the hook vertebral joint, and the herniated disc compresses the cervical spinal nerve root passing through the area, thus generating radicular compression symptoms. Symptoms (1), neck pain, stiffness, restricted movement, like “falling pillow”; (2), neck hyperextension can produce severe pain, and can be radiated to the scapula or occiput, (such as the symptomatic side of the upper limb elevated over the head, the patient feels more comfortable, so the patient likes to stay in this special position when lying down in bed, sleep with the head resting on the hand or the head tilted toward the affected side); (3), the patient can feel the pain in the neck, and can feel the pain in the shoulder blade or occiput, and can feel the pain in the neck. (If the symptomatic side of the upper limb is lifted over the head, the patient feels more comfortable, so the patient likes to keep this special position when lying in bed, sleeping with the head on the hand, or tilting the head to the affected side. Physical signs: (1) the neck is in a rigid position; (2) paravertebral tenderness and percussion pain in the diseased segment, and tenderness between the spinous processes of the lower cervical vertebrae and the medial part of the scapula; (3) positive cervical spinal nerve root tension test and Spuring test; (4) changes in sensation, movement, and reflexes in the innervated area of the affected nerve root. The innervating muscles may have atrophy and hypokinesia. ②, central cervical disc herniation herniation site in the center of the spinal canal, the spinal cord in front, can compress the spinal cord in front of the bilateral spinal cord and produce bilateral spinal cord compression symptoms. Symptoms (1), varying degrees of limb weakness, the lower limbs tend to be heavier than the upper limbs, manifested as unsteady walking; (2), incomplete or complete paralysis of the limbs in severe cases; (3), dysfunction of urination and defecation, manifested as urinary retention and defecation difficulties. Physical signs (1), varying degrees of decline in muscle strength of the limbs; (2), sensory abnormalities, both superficial and deep sensations can be involved, depending on the level of sensory abnormalities in different sections of the herniated intervertebral discs; (3), increased muscle tone of the limbs; (4), hyperreflexia of the tendons, positive patellar clonus and ankle clonus can be seen, and pathological signs such as Hoffmann’s and Openheim’s signs can be positive. (iii) Paracentral cervical disc herniation The protruding part is on one side and between the cervical spinal nerve root and spinal cord, compressing the unilateral nerve root and spinal cord. In addition to symptoms and signs of lateral type, there are different degrees of unilateral spinal cord compression symptoms, manifested as atypical Brown-Sequard syndrome. This type is often due to severe radicular pain masking the spinal cord compression, and once the spinal cord compression is manifested, the condition is more serious. Diagnostic basis ①, mostly seen in young adults, most of the patients have obvious history of head and neck trauma or occupational history of prolonged low head position work. Most patients have a history of head and neck trauma or occupational history of working in a low position for a long period of time. ② Clinical symptoms and signs of spinal nerve root or spinal cord compression can appear after the onset of the disease. (iii) Clinical symptoms may change at an early stage with the patient’s position change, rest and treatment. This fluctuating feature is due to the protruding and constant dislocation, but it disappears after the protruding nucleus pulposus forms adhesion with the surrounding tissues. ④, CT, magnetic resonance imaging and other imaging tests confirmed as herniated disc. 4.Treatment principle Non-surgical treatment: Non-surgical treatment is the mainstay; if spinal cord compression symptoms appear, surgical treatment should be performed as early as possible. Traction: The original non-degenerative disc herniation can be restored to its disc height by traction, and part of the herniated material is expected to be returned. It is generally believed that intermittent traction is more effective than continuous traction, with 10 days as a course of treatment. Tui na: in the acute stage, light manipulation is adopted; heavy manipulation may aggravate disc herniation and spinal cord and nerve root injury. Physical therapy: it is effective for light cases with only nerve root irritation symptoms, in which intermediate frequency and ultrashort wave are more effective. Drugs: Sedative and analgesic drugs can be used for those with severe pain, such as Mai Zhi Ling and Xiluo Bao. Acute stage treatment: acute herniation of intervertebral disc, local congestion, inflammation and edema. Drugs and physical therapy are the mainstay. Mannitol injection 250ml, pressurized drip; 0.9% sodium chloride injection 250ml, plus dexamethasone injection 10-15mg, drip, 2/day, 3-5 days for 1 course of treatment. Fifth, the prevention of cervical disc herniation ①, do not doze off in the car, it is best to rest your head on the back of the car seat, so as to avoid the driver braking caused by the occurrence of this disease ②, to do sports to maintain the correct posture, do not make the neck over-extension, over-flexion, excessive left and right rotations, do not throw the head ③, the work of the work time should not be too long, an hour to get up and move around.
