Because of the long course of cervical spondylosis, there are more pathological changes and the clinical manifestations are more complicated. Therefore, doctors have to pass a more comprehensive and detailed examination when diagnosing cervical spondylosis, and even choose certain special examination methods to confirm the diagnosis. After the doctor receives the patient, the first light is to inquire about the medical history. The history includes the cause of the disease, the history of trauma, the nature and time of the first symptoms, the evolution of the symptoms and the treatment and efficacy received. In particular, the nature and characteristics of the first symptoms and the evolution of symptoms can be of great help in diagnosis and differential diagnosis. For example, if there is neck pain in the morning after waking up, which is relieved after activity and accompanied by lumbar pain, it is generally considered to be due to osteophytic changes; discomfort or soreness in the neck may indicate cervical disc degeneration, numbness in one upper limb or onset from pain, often due to hook joint instability or osteophytes; if the disease starts suddenly, it is mostly due to compression or irritation of the 2nd or 3rd segment of the vertebral artery. A further task for the physician is physical examination. Physical examination, including the presence of local pressure points, cervical spine range of motion and some cervical spine test examinations. In addition, in order to localize the diagnosis or differential diagnosis, examination of the nervous system such as sensation, movement and reflexes are sometimes selected as appropriate. For example, the distribution of sensory disorders in the hands and upper extremities is directly related to the localization of the affected cervical vertebrae. Therefore, the diagnosis can be facilitated by the examination of sensory disorder demarcation, degree of accumulation and other sensations other than pain, such as warmth, touch and deep sensation. Motor examination, mainly muscle tone, muscle strength, gait and other aspects of the examination. Reflex examination, which generally includes deep and superficial reflexes such as biceps reflex, triceps reflex, brachioradialis reflex and pathological reflexes such as Hoffman’s sign. Routine auxiliary examinations. Mainly X-ray examination, which can be taken in cervical orthogonal, lateral and oblique plain films, and also in dynamic (hyperflexion and hyperextension) lateral films. Special auxiliary examinations, such as tomography (or somatography), myelography, vertebral arteriography CT, and magnetic resonance imaging, are available. In addition, cerebrospinal fluid examination, electromyography, cerebral hemogram and other tests can be performed as needed for differential diagnosis. The staging and typing of cervical spondylosis can be distinguished according to pathological changes or clinical features. In clinical practice, cervical spondylosis is generally classified into cervical, nerve root, spinal cord, vertebral artery, esophageal compression and sympathetic nerve types. The diagnosis can be confirmed if the clinical symptoms and X-ray are consistent with cervical spondylosis; those with clinical manifestations and no abnormalities on X-ray can be diagnosed with the exception of other disorders; those without clinical symptoms and signs and abnormalities on X-ray should not be diagnosed hastily. In terms of specific clinical manifestations, the above types often appear together, especially the vertebral artery type and the sympathetic nerve type, because there are a large number of sympathetic nerve fibers surrounding the vertebral artery, so the two types often exist together. For patients with cervical spondylosis, once they have symptoms such as neck discomfort, arm numbness, lower limb weakness and dizziness, they should go to the hospital and go through the above-mentioned series of tests to make a clear diagnosis.
