As people’s modern living habits change and they spend more and more time looking down at their cell phones and working, more and more patients come to the author’s clinic for neck and shoulder discomfort, and they are getting younger and younger. When people see me, they ask, “Director Xiao, am I suffering from cervical spondylosis?” . So what is the problem of cervical spondylosis? Cervical spondylosis is one of the common and frequent diseases in middle-aged and elderly people. It is a common disease based on degenerative changes of cervical discs, followed by pathological changes of cervical disc protrusion, osteophytes and ligamentous hyperplasia, stimulating or compressing the adjacent nerves and blood vessels and causing corresponding clinical symptoms. Its incidence is about 10-15% in adults, more in men than in women, about 3:1, often after middle age, about 25% of people over 50 years old and about 50% of people over 60 years old have suffered from cervical spondylosis, and its incidence increases with age. Chronic strain is the primary culprit in the development of cervical spondylosis. Long-term injury to local muscles, ligaments and joint capsule can cause local hemorrhage and edema, inflammatory changes, gradual inflammatory mechanization at the site of the lesion, and the formation of osteophytes, which affect local nerves and blood vessels. Trauma is a direct factor in the occurrence of cervical spondylosis. Often, people already have varying degrees of pathology prior to trauma, putting the cervical spine at high risk, and trauma directly induces the onset of symptoms. Poor posture is another major cause of cervical spine injury. Long hours of low work, lying in bed watching TV, reading books, like high pillows, long hours of computer operation, violent rotation of the neck or head, sleeping in a moving car, all these bad posture will make the neck muscles in a long-term fatigue state, prone to injury. Cervical spine dysplasia or defects are also one of the causes of cervical spondylosis that cannot be ignored. The Asian race has a smaller spinal canal volume compared to Europeans and Americans, which makes it easier for the spinal cord to be compressed and produce symptoms. As shown in the figure below, cervical spine hyperplasia compresses the nerve roots of the spinal cord. The symptoms of cervical spondylosis are very rich, diverse and complex, and most patients start with mild symptoms that gradually worsen later, while some have more severe symptoms. Often one type is mainly combined with several other types together, which is called mixed cervical spondylosis. 1.Cervical and shoulder pain can be radiated to the head and occipital region and upper limbs; 2.Heavy feeling on the back of one shoulder, weakness of upper limbs, numbness of fingers, loss of skin sensation of limbs, weakness of hand grip, and sometimes unconscious grip falling to the ground. 3.Serious typical manifestations are: weakness of the lower limbs, unstable walking, numbness of the second foot, and the feeling of stepping on cotton when walking. 4.The most serious cases even have loss of control of bowels and urine, sexual dysfunction, and even tetraplegia. After understanding the onset and clinical manifestations of cervical spondylosis, what should be done? First, to avoid too long ambulation in general in the ambulatory work 1 to 2 hours, we must properly back cervical spine, or look to the sky for a moment, so as to relieve the cervical fatigue has a great benefit. In addition, adjust the height of the desk and seat, so that when writing do not excessively low, can also play a role in reducing the purpose of ambulation; Second, the appropriate cervical muscle exercise: cervical spine muscle strain is the cause of cervical spondylosis is also the clinical manifestations of cervical spondylosis. Cross your hands to the back of the head and neck, force the head and neck to the back of the upper lift, while the head and neck to the back of the force back (as far as possible to keep the cervical vertebrae relatively immobile, do muscle contraction training of the back of the neck), a relaxation, repeatedly 20 ~ 50 times, 2 ~ 3 times a day exercise; Third, pay attention to the reasonable use of pillows: supine with a high pillow is the most common mistake people make, the correct method is to choose a height and my fist equal High oblong pillow, cushioned in the cervical spine after the middle part, not on the skull, which not only has a good preventive effect on cervical spondylosis and can promote early recovery of cervical spine patients, in addition, also pay attention to not use high pillows, wide pillows, short pillows, hard pillows; fourth, appropriate cervical traction. A part of the upper limb pain, numbness-based cervical spondylosis, the use of cervical traction when the symptoms are serious can obtain good results; fifth, surgery for cervical spondylosis diagnosis is clear, nerve root compression symptoms are serious, no significant improvement in symptoms after conservative treatment should take surgery, and for patients with spinal cord cervical spondylosis, that is, patients who mainly manifest symptoms such as walking weakness of both lower limbs, unstable walking, surgery should be implemented as soon as possible. For patients with spinal cord cervical spondylosis, i.e. patients with symptoms such as weakness of both lower limbs and unstable walking, surgery should be performed as early as possible to obtain good recovery effect, because the treatment effect of such patients is closely related to the length of nerve compression. With the development of science and technology, surgery for cervical spondylosis is safe, effective and less traumatic, so there is no need to avoid treatment. The main surgical methods for cervical spondylosis are as follows: 1. Anterior cervical surgery: as the name implies, the surgery is performed in front of the neck, and most anterior cervical surgery is minimally invasive, with small surgical incisions and fast postoperative recovery. The surgery mainly removes the protruding and deformed intervertebral discs, and for those with osteophytes, also removes the osteophytes and the hook vertebral joints on both sides to avoid residual possible pressure-causing materials. A variety of reconstructions are performed after removal of normal structures, mostly using plates and fusion devices to reconstruct the height and stability of the cervical spine. In recent years, artificial disc replacement has also emerged, which can preserve the intersegmental motion of the cervical spine and has good clinical efficacy for suitable patients. 2.Posterior cervical surgery: i.e. surgery from the back of the neck, applicable to multi-segmental cervical spondylosis with spinal stenosis or ossification of the posterior longitudinal ligament. The posterior approach mainly achieves indirect decompression by removing all or part of the posterior vertebral plate, which is less risky than the anterior approach, simple to expose, and more effective for patients whose cervical spine itself has physiological curvature. Procedures such as posterior single-opening vertebroplasty have been widely adopted as they can preserve intercervical mobility and have a lower incidence of posterior convexity deformity and adjacent segmental degeneration.
