Cervical spondylosis is called cervical spondylosis when the cervical disc degeneration itself and its secondary changes irritate or compress the adjacent tissues (spinal cord, nerve roots, sympathetic nerves and vertebral arteries) and cause corresponding symptoms and signs. The degenerative factors of cervical spondylosis are the main cause of the occurrence and development of cervical spondylosis, especially in congenital developmental spinal stenosis conditions are more likely to develop into cervical spondylosis. Other factors include: chronic strain injury: such as poor sleep posture (pillow too high), improper work posture (prolonged low work), poor daily living habits (prolonged playing of mahjong, poker, watching TV); deformity; trauma; and inflammation, etc. can be regarded as predisposing factors or called secondary factors. Clinical characteristics of cervical cervical spondylosis: complaints of abnormal sensation such as pain in the neck, shoulder and occipital area, accompanied by corresponding pressure points and a stiff neck; a few patients may have transient upper limb numbness, but no muscle strength disorder. Excluding other disorders: mainly excluding neck sprain, frozen shoulder, rheumatic myofibrositis and other non-cervical origin of neck and shoulder pain. Treatment principles: Avoid and eliminate various triggering factors: pay attention to sleep and work position, avoid long-term neck bending, head and neck trauma, strain and cold stimulation. Non-surgical treatment is the main treatment, physical therapy, massage, external use of neck circumference, light weight (1-1.5kg) traction therapy, etc. can make the symptoms relieved. In the acute stage, interspinous and paraspinous nerve block therapy is more effective. Nerve root type cervical spondylosis overview diagnostic criteria: with more typical radicular symptoms such as pain, numbness, sensory hypersensitivity and diminished sensation in the upper extremity, and the scope is consistent with the area innervated by the cervical spinal nerve. X-rays may show abnormalities such as changes in cervical curvature, vertebral instability and spur formation, and MR imaging clearly shows the local pathological anatomy, including nucleus pulposus protrusion and prolapse, and the site and extent of spinal nerve root involvement. The clinical presentation is consistent with the imaging findings at the segmental level. Substantial cervical skeletal lesions (tuberculosis, tumors, etc.), thoracic outlet syndrome, carpal tunnel syndrome, ulnar, radial, and median nerve injuries, periarthritis of the shoulder, tennis elbow, and biceps tenosynovitis, which are predominantly upper extremity pain disorders, should be excluded. Pain point closure is generally ineffective. Treatment principles: non-surgical treatment, continuous (or intermittent) traction of the head and neck, cervical braking and correction of poor posture are effective, and the application of nerve block therapy in the acute stage is effective. In cases of nucleus pulposus protrusion and prolapse, the clinical manifestations are consistent with the imaging of spinal nerve root involvement in the segment, and those who have not been treated with regular non-surgical therapy for more than 3 months can be considered for myelolysis. Surgery may be considered for those with progressive muscle atrophy and neurological dysfunction. Spinal cord type cervical spondylosis diagnostic criteria clinically has the manifestation of spinal cord compression, the cone bundle sign is the main feature, depending on the site of the bundle nerve fiber involvement is divided into the following three types: ①, central type (also known as upper limb type), ②, peripheral type (also known as lower limb type), ③, anterior central vascular type (also known as limb type). The phenomenon of numbness in the limbs is mainly due to the involvement of the thalamic tract of the spinal cord. Reflex disorders are mainly manifested as abnormal physiological reflexes and pathological reflexes. The defecation and urination dysfunction mostly appears in the later stages, initially with urinary urgency, poor voiding, urinary frequency and constipation, and gradually with urinary retention or urinary and fecal incontinence. Treatment principle Non-surgical treatment is still the basic treatment for this type, especially the early central type (upper limb type) and the anterior central vascular type (extremity type), about nearly half of the cases can obtain more obvious results. However, the disease should be closely observed and any rough handling and manipulation should be avoided. Once the condition worsens, surgery should be performed early to prevent degeneration of the spinal cord. The selection of surgical cases: ①, acute progressive cervical spinal cord compression symptoms, confirmed by clinical examination or other tests (magnetic resonance, CT scan, etc.), should be operated as soon as possible; ②, a long duration of the disease, the symptoms continue to worsen and the diagnosis is clear; ③, although the spinal cord compression symptoms are moderate or mild, but the non-surgical treatment for more than 1-2 courses of treatment does not improve and affects workers. The most effective surgical approach and procedure are selected depending on the condition, the patient’s general condition, the operator’s technical condition and the surgical operation habit. Diagnostic criteria for vertebral artery cervical spondylosis: (1) a history of vertebrobasilar artery ischemia (mainly vertigo) and/or sudden collapse; (2) a positive neck rotation provocation test; (3) an X-ray showing intervertebral joint instability or hook joint osteophytes; (4) the presence of sympathetic symptoms; (5) excluding ophthalmogenic and otogenic vertigo (6), except for insufficiency of basilar artery supply caused by compression of the first segment of the vertebral artery (the vertebral artery before entering the 6th cervical foramen); (7), except for neurosis and intracranial tumors; (8), the diagnosis of this disease, especially the localization before surgery, should be based on MR, DSA or vertebral arteriography; color Doppler examination, vertebral arteriogram and cerebral hemogram can be of reference value. Non-surgical treatment is the basic treatment for this type, and more than 90% of cases can be treated, especially those caused by cervical instability, and most of them can be cured without sequelae. Surgery can be considered only in the following three cases: ①, obvious cervical vertigo or sudden collapse with at least two episodes; ②, no treatment by non-surgical therapy, and it affects normal life and workers. (3) Those who are confirmed by digital vascular subtraction, vertebral arteriogram or MRA.
