Cervical spondylosis is a clinical syndrome caused by degenerative degeneration of cervical discs, hypertrophy and hyperplasia of cervical vertebrae, as well as cervical injury, resulting in osteophytes of cervical vertebrae, or prolapsed discs and thickened ligaments, which stimulate or compress the cervical spinal cord, cervical nerves and blood vessels and produce a series of symptoms. The main manifestations are neck and shoulder pain, dizziness and headache, numbness of upper limbs, muscle atrophy, spasm of both lower limbs in severe cases, difficulty in walking, and even paralysis of all four limbs, urinary and fecal disorders, and paralysis. It occurs mostly in middle-aged and elderly people, with a higher incidence in men than in women. Disease classification (1) Nerve root type: The stimulation of degenerative changes of cervical intervertebral disc or osteophytes compresses the spinal nerve roots, causing sensory and motor dysfunction of the upper limbs, often manifesting as motor impairment or sensory numbness of one upper limb segment.
