The common use of cell phones and computers has given rise to a new term: low-headed people. Because everyone in the use of cell phones and computers are in the head down well! The cervical spine is in a state of forward flexion when the head is bowed, which is the opposite direction of the normal cervical physiological pronation. What happens when the cervical spine is flexed forward for a long time and often? First of all, the cervical spine back muscles because of prolonged stretching and strain symptoms, neck and shoulder pain, this symptom is too common; then is the front of the cervical disc degeneration, and bulging, protrusion or even prolapse; next is the cervical spine curvature abnormal, the normal convexity disappeared, the side view of the cervical vertebrae become straight, serious will also be but backward convexity; cervical stability is reduced; finally there is osteophytes, that is We often refer to bone spurs. These structural abnormalities can compress and irritate the adjacent tissues and produce symptoms that are clinically known as cervical spondylosis. The cervical spine contains the spinal cord, nerve roots, vertebral arteries, and sympathetic ganglia. Where these structural abnormalities compress and stimulate, the corresponding symptoms will be produced, which is what type of cervical spondylosis. For example, compression of the spinal cord leads to weakness of the lower limbs and unstable walking. Once diagnosed, spinal cord cervical spondylosis basically requires surgery because the spinal cord inside the cervical spine is so important and fragile that there is little wiggle room and time for the patient to think and wait; for vertebral artery and sympathetic cervical spondylosis, the current clinical treatment is mainly conservative because the symptoms are relatively mild and the efficacy of surgery is not very certain, so it is more prudent to do surgery. One of the greater variables is the neurogenic cervical spondylosis, and in the past textbook surgery, most scholars thought that conservative treatment would do. However, now there is a new point of view. The brain extends down to the spinal cord, which is mainly composed of neuronal cells. The motor neurons in the anterior corner of the spinal cord send outgoing nerve fibers to send brain instructions, and the posterior corner of the spinal cord receives various signals from various parts of the body through afferent nerve fibers. They are responsible for sensory, motor, reflex and various physiological activities in a particular part of the body. When the nerve roots are compressed, the sensory aspect is successively pain, numbness and sensory loss, and the motor aspect is weakness, reduced reflexes and muscle atrophy. Because the nerve roots in the cervical spine are responsible for the sensation and movement of the neck, shoulders and upper limbs, the symptoms of cervical spondylosis of the nerve root type are distributed in this area. The symptoms we usually feel, such as neck and shoulder pain, radiating pain in the upper limbs and numbness in the hands, are the manifestations of neurogenic cervical spondylosis. Neurogenic cervical spondylosis develops slowly from mild to severe, and then suddenly worsens due to some triggering factors, such as cervical spine trauma, long hours of desk work, etc. When symptoms such as pain and numbness are mild, they can be relieved by rest, reducing head bowing, applying heat to the neck and shoulders, or wearing a neck brace. If the symptoms are so severe that it affects your work life, for example, when it affects your sleep, you should see a doctor and receive conservative medication, including painkillers, blood-boosting drugs to improve microcirculation and neurotrophic drugs, sometimes combined with physiotherapy and hot compresses. If the symptoms are very severe, so severe that they are unbearable, and if you do not insist on medication, you will have to undergo surgery. Patients who have been treated conservatively for 2-3 months without significant relief will also have to undergo surgery. Surgery is also indicated if symptoms recur, for example, every 6 months for more than 3 consecutive episodes. Finally, there is another condition that one must be careful of. Sometimes the symptoms are mild, but they persist and slowly lead to dullness of sensation and muscle weakness, or even muscle atrophy, and one must also undergo surgery.
