Cervical disc herniation, in which the nucleus pulposus or part of the cartilaginous disc of the cervical intervertebral disc protrudes into the spinal canal, is one of the more common spinal disorders in clinical practice and is second only to lumbar disc herniation in terms of incidence. Depending on the location of the protrusion, it can be divided into three types: lateral, paracentral, and central, causing irritation and compression of the nerve root or spinal cord. As the most common is the disc of cervical 5-6 or cervical 6-7 both herniated outward at the same time, thus producing symptoms of brachial nerve root involvement on that side. The common cause is a sudden sprain or weight bearing on the neck. Symptoms of cervical disc herniation include: 1. Pain: Patients feel pain and stiffness in the neck, sometimes involving the back, and when a cervical disc herniation compresses a nerve, it can also cause radiating pain in one or both upper extremities; 2. Dizziness: If patients feel dizzy, it may be caused by a cervical disc herniation; 3. If the herniated cervical disc compresses the spinal cord, the patient may experience unstable walking and cotton-like sensation, and needs to go to the hospital for consultation.
