Posterior cervical single-opening, canal enlargement kyphoplasty is a common surgical procedure for the treatment of multi-segmental cervical disc herniation and spinal cord-type cervical spondylosis. It involves making an incision in the back of the neck right in the middle, cutting off the vertebral plate of one cervical vertebra, lifting the cervical vertebral plate backward, enlarging the cervical spinal canal, causing the compressed spinal cord to drift backward, and relieving the spinal cord compression, thereby relieving symptoms such as unstable walking, numbness in the hands and feet, weakness in the hands and feet, and neck pain. The extent of posterior cervical spine surgery is evaluated based on preoperative X-rays, CT and MRI, and where the spinal cord compression is heavy, the compression is released. In some patients, the spinal cord is also heavily compressed in front of the spinal cord, and if the symptoms do not recover well after surgery, anterior cervical spine surgery is usually required again 3 months after surgery. The most common postoperative complication of posterior cervical unicompartmental surgery is cervical 5 nerve root palsy, which has a probability of occurrence ranging from 0-50% and can occur immediately after surgery or at a later time, manifesting as numbness and pain in the shoulders and upper arms and weakness in the upper extremities due to the pulling of the cervical 5 nerve root caused by the posterior drift of the spinal cord. The majority of patients recover within 2 years after surgery. Treatment includes wearing a cervical brace, and symptomatic treatment with analgesics, glucocorticoids, and nerve-nourishing medications can be given. Another common complication of posterior cervical spine surgery is cervical axial pain, which is much less likely to occur after surgery due to the optimization of our posterior cervical spine surgery approach. If a patient develops postoperative axial pain, it can usually be relieved by symptomatic treatment with pain relief. Postoperative cervical spine patients are required to wear a cervical brace, usually for 2-3 months. Since most patients have unstable walking before surgery, it is best to have someone with you when walking during the initial postoperative recovery period to avoid falls that can cause serious complications such as spinal cord injury. Finally, I wish you a speedy recovery!
