Sequelae two to three years after cervical spine surgery may include muscle strain, limited mobility and secondary degeneration. However, in general, the likelihood of sequelae of surgery is relatively small. 1. Muscle strain: Two to three years after surgery, muscle stiffness and strain are likely to occur, which may limit activities. At this time, you should pay attention to rest and avoid heavy activities. 2. Restricted activity: Two to three years after surgery, patients are likely to be restricted in their ability to move the cervical spine and are unable to perform normal activities. 3. Secondary degeneration: After cervical spine surgery, the patient will have stress on the adjacent segments of the affected area, and two to three years later, secondary degeneration may occur in the adjacent parts of the affected area, which will show symptoms of cervical spine pain. Cervical spine surgery is a relatively mature surgical technique, and the occurrence of sequelae two or three years after surgery should be extremely unlikely. After cervical spine surgery, you should have regular follow-up appointments and follow your doctor’s instructions for recovery.
