Postoperative spinal cord cervical spondylosis may be associated with non-healing wound infections, cerebrospinal fluid leaks, and nerve damage. The details are as follows: 1. Wound infection without healing: postoperative incision infection or infection inside the incision may occur, and the incision will not heal. With close attention to aseptic operation during surgery and postoperative antibiotic application, incision infection and other situations usually do not occur. 2. Cerebrospinal fluid leakage: Cerebrospinal fluid leakage is a rare complication after cervical spine surgery because of the special structure of the cervical spine, it is easy to injure the dura mater or arachnoid membrane during surgery, and cerebrospinal fluid leakage may occur. In addition, it may also be caused by infection, so postoperative anti-infection treatment is more important. 3. Nerve damage: Vocal cord paralysis or vocal difficulties may occur after surgery, mainly due to the damage of the recurrent laryngeal nerve, which may be recovered after exercise. Complications after spinal cord spondylosis should be treated promptly to prevent the condition from deteriorating.
