The anatomical characteristics of the cervical spine and the pathological changes of cervical spondylosis result in a complex and diverse clinical presentation of cervical spondylosis. However, because of the differences in pathological changes and the degree of impact of each patient, certain symptoms often appear together and follow a certain pattern. Therefore, different clinical typing is basically given according to the performance of the patient. The clinical manifestations of each specific type of cervical spondylosis are as follows: cervical type cervical disc degeneration, acute injury to the neck muscles, ligaments and joint capsule, and small joint misalignment are the basic etiology of this type. It causes discomfort such as cervical pain, swelling and numbness in the cervical spine locally or radially, and about half of the patients can have limited neck movement or forced position as a result. Patients generally complain of abnormal sensations such as pain in the head, neck, shoulder and arm, with corresponding pressure points. Zhang Xuexue, Department of Pain, The First Affiliated Hospital of Nanchang University Neurogenic type Due to cervical disc herniation, osteophytes, degeneration of the hook vertebral joint and posterior joints, irritation or compression of the spinal nerve roots is caused, producing clinical symptoms such as weakness of the upper limbs, numbness of the fingers and abnormal sensation. Generally, patients with neurogenic cervical spondylosis have more typical symptoms of numbness and pain in one upper limb, and the extent of symptoms is consistent with the area innervated by the cervical spinal nerve. The intervertebral foramen squeeze test and nerve root pull test are positive, and the pressure pain on the side of the spinous process is accompanied by radiating pain on the affected upper limb. Spinal cord type cervical disc herniation, bone spur at the posterior edge of the vertebral body, hypertrophy of the displaced ligament of the vertebral body, and spinal cord injury cause spinal cord compression and ischemia, resulting in spinal cord conduction dysfunction. It can be divided into two types: central type and peripheral type. In the central type, the onset starts from the upper extremity and progresses to the lower extremity; in the peripheral type, the onset starts from the lower extremity and progresses to the upper extremity. Both types can be divided into mild, moderate and severe degrees. The clinical symptoms of spinal cord type cervical spondylosis are mainly abnormal sensation of the medulla, motor and reflex disorders, such as weakness of the lower limbs, heavy feeling of lifting, claudication, hyperactive tendon reflexes, and even spastic paralysis and urinary and fecal incontinence. Vertebral artery stenosis Due to degeneration of the hook vertebral joint or disc degeneration, the total length of the cervical spine is shortened and the balance between the vertebral artery and the length of the cervical spine is disrupted, stimulating and compressing the vertebral artery and causing insufficient blood supply to the vertebral artery, resulting in symptoms such as migraine, tinnitus, vertigo, loss of vision, and sudden collapse. Positive rotational neck test. Sympathetic type If the intervertebral disc degenerates and irritates or compresses the sympathetic nerve fibers in the neck, it can cause a series of sympathetic reflex symptoms, such as nausea, blurred vision, tinnitus, and tachycardia. This type is often associated with vertebral artery type, and sometimes it is difficult to diagnose independently. The esophageal compression type is caused by the compression of the esophagus by a beak-like bone spur at the anterior edge of the vertebral body. The main clinical symptoms are dysphagia and hoarseness. Mixed type. There is often a mixture of symptoms of the above types, and this mixture makes the clinical manifestation of cervical spondylosis more complex.
