After cervical spine radiofrequency ablation, there may be some long-term complications, or sequelae, which are commonly seen as follows: First, there is a possibility of recurrence of cervical spondylosis. This condition is often seen when the patient does not continue to protect the cervical spine and do the corresponding functional exercises in accordance with the doctor’s medical advice after having the surgery for relief. For example, local disc herniation or ligamentous hypertrophy may be produced, which may lead to recurrence of cervical spondylosis. Second, there is a possibility of producing pain at the puncture site. When this procedure is done, some thicker and longer diameter instruments are used for puncture. If the patient is sensitive to puncture pain, there may be some long-term pain at the puncture site. However, this situation is relatively rare. Third, it may cause some abnormal sensation. After the cervical spine radiofrequency ablation, it is possible that due to the stimulation of some nerves, abnormal sensations such as numbness and coldness may be produced in the neck, shoulder or some other parts of the upper limbs. The abnormal sensations may persist for a long time, but have no relevant effect on the patient’s movement and other sensations.
