Leg twitching after cervical spine surgery may be related to factors such as nerve recovery, nerve damage or low blood calcium. 1. Nerve recovery: the cervical spinal cord belongs to the central nervous system. Although the nerve compression is lifted after surgery, the nerve cells that have been compressed for a long time will recover very slowly, and twitching of the legs may occur. 2. Nerve damage: the nerves around the cervical spine may be damaged during the operation, and leg twitching may also occur. 3. Low blood calcium: Calcium ions have the effect of reducing neuromuscular excitability. In the case of low blood calcium, the lack of calcium ions will cause neuromuscular excitability, which will cause muscle twitching. After cervical spine surgery, if the twitching of the legs is not relieved, you should go to the hospital in time, and carry out targeted treatment after clarifying the cause of the disease.
