Vertebral artery cervical spondylosis: Dizziness is a common symptom in patients with vertebral artery cervical spondylosis. Patients induce vertigo symptoms by changing their position due to extension or rotation of the neck. The vertigo caused by ischemic lesion of the vestibular nerve nucleus usually lasts for a short period of time and disappears in a few seconds to a few minutes, and the patient may have mild disorientation and movement disorder at the onset, which is manifested as unstable walking or tilting to one side; the vertigo caused by ischemic lesion of the vestibular nerve nucleus is not accompanied by impaired consciousness. The vertigo caused by vestibular neuropathy is central vertigo; the vagal ischemic lesion is peripheral vertigo. Some patients have nausea and cannot raise their heads during acute attacks. A few patients have diplopia, eye tremor, tinnitus and deafness. Some patients can hear murmur of vertebral artery due to distortion and obstruction of blood flow on the affected clavicle. On palpation of the thumb in the posterior neck, the affected vertebra can be felt to be rotated and displaced to one side, and there is obvious pressure pain in the spinous process and the displaced synovial joint. Nerve root type cervical spondylosis: mainly neck and shoulder discomfort accompanied by numbness or radiating pain in the upper limbs For nerve root type and vertebral artery type cervical spondylosis, percutaneous laser disc decompression (PLDD) can be used for treatment at the early stage of onset.
