Cervical 4-5 herniation refers to the nucleus pulposus of the 4th and 5th cervical intervertebral discs protruding out of the vertebral canal at the back, which can compress the dural sac, spinal cord and nerve roots at the back and cause a series of clinical symptoms. Due to ageing, the intervertebral disc degenerates and the nucleus pulposus of the intervertebral disc protrudes outward under the action of external force. If it occurs between the fourth and fifth cervical vertebrae, the patient may experience pain in the neck and shoulder area and radiating pain in the upper limbs, and some patients may experience instability in walking on the lower limbs and the sensation of stepping on cotton. If the treatment is not timely or further development, spastic paralysis of different degrees can occur. Cervical disc herniation is mostly a chronic progressive disease, and the triggering factors are long-term work, exertion, cold or trauma, etc., which can induce cervical spondylosis symptoms. Patients with 4 or 5 herniated cervical vertebrae are advised to actively cooperate with their doctors and undergo regular treatment as soon as possible to minimize the adverse consequences of the disease.
