Wrist weakness after cervical spine surgery may be caused by hypokalemia, incision edema or hematoma compression of cervical cord or nerve, cervical cord injury, etc. It can be treated by general treatment, medication, physical therapy and other methods. 1. Hypokalemia: If the time of water and food fasting after cervical spine surgery is too long or the rehydration fluid is inappropriate, it is easy to lead to electrolyte disorders, resulting in hypokalemia, which will make the patient have wrist weakness after cervical spine surgery. It can be treated with drugs such as potassium chloride injection as prescribed by doctor to correct electrolyte disorder and eliminate symptoms. 2. Incision edema or hematoma compressing the cervical cord or nerves: Because the blood vessels and nerves in the neck are rich, incision edema is easy to be formed when there is more local exudation after surgery. If the hemostasis is not strict during the operation, there is a possibility of incisional hematoma after the operation. Incisional edema or hematoma compressing the cervical medulla or nerves can have an effect on the nerve conduction function, resulting in wrist weakness after cervical spine surgery. Vitamin B injection and mannitol injection can be used to promote the absorption of edema and hematoma and eliminate the symptoms. 3. Cervical cord injury: the operating space of cervical spine surgery is small, and improper operation may cause cervical cord injury, resulting in wrist weakness after cervical spine surgery. Nutritional drugs such as methylcobalamin tablets and vitamin B1 tablets can be used as prescribed by the doctor, and physical therapy such as acupuncture can be used to promote the recovery of nerve function. If wrist weakness occurs after cervical spine surgery, it is necessary to consult a doctor in time for standardized treatment, do not do it by yourself, so as to avoid serious adverse consequences.
