Yesterday I performed a posterior single-opening laminectomy with internal fixation of the cervical arch nail from the third to the seventh cervical vertebrae in a 66-year-old woman with severe cervical spondylosis. The patient’s preoperative cervical CT and MRI indicated a high degree of cervical spinal canal stenosis, which was only 1/5 of the normal spinal canal diameter, making the operation very difficult and risky, and any negligence during the operation could damage the spinal cord and lead to paralysis. After nearly four hours of surgery, the patient left the operating room safely and had good postoperative limb movement. This morning I checked the room, and the patient complained that most of the preoperative symptoms (numbness of the limbs and the feeling of thoracic and abdominal strapping) were significantly relieved or even disappeared. As to whether the patient’s preoperative unsteadiness in walking was relieved or disappeared, we will have to wait until the patient walks on the ground two days later. However, I was very pleased to see the patient’s satisfied smile during the checkup. Addendum: Ten days after the surgery, I checked the patient’s room, and the patient reported that the numbness of the limbs had disappeared, and that he was able to walk very steadily and no longer had the feeling of stepping on cotton.
