Motor conduction tract involvement is one of the clinical manifestations caused by primary intraspinal tumors. When the cervical spinal cord is partially compressed, with the increase of tumor, the symptoms of spinal cord conduction bundle compression will gradually appear on the basis of the original symptoms, such as compression of spinal cord thalamus bundle, which may lead to hyperalgesia or disappearance of pain and temperature sensation below the contralateral side of the lesioned segment; compression of posterior bundle, which may lead to hyperalgesia of deep sensation; involvement of motor conduction bundle, which may lead to upper motor neuron paralysis in the limbs below the ipsilateral lesioned segment, and spinal cord hemisection syndrome is a specific symptom of intradural extramedullary tumor. The spinal cord hemisection syndrome is a specific symptom of extramedullary tumor. What are the preventive measures for primary intradural tumors? Prevention There is no effective preventive measure for this disease. If intravertebral canal tumor can be detected early and treated with surgery early, most of them can achieve good clinical results. Some patients with large intraspinal tumors or located in high cervical spine may die due to respiratory failure after surgery or recur after a period of time after surgery. As for the recovery of spinal nerve function, it is related to the degree and duration of spinal cord compression of the patient. Treatment Patients with mild symptoms or spontaneous remission can be treated conservatively with repeated, multiple physical examinations and mri reviews (note: there is a risk of recurrence and bleeding from spinal cord injury). However, the only effective treatment is surgical resection of the tumor, and since primary intravertebral tumors are predominantly benign, they can be cured by surgical resection in about 3/4 of cases. Therefore, surgical resection of intravertebral canal tumors should be strived for, and even if complete resection is not possible, partial or bulk resection should be performed to reduce or relieve the compression and damage of the tumor on the spinal cord. Once the diagnosis is clear, surgical conditions should be created actively, and regardless of the degree of spinal cord compression, surgery should be performed in a timely manner. Surgery is risky, and symptoms can be recurrent. The risk of surgery varies according to its functional location, and exogenous cases have few postoperative defects. The appropriate treatment should be chosen. Intraoperative spinal cord evoked potential monitoring helps to reduce neurological complications. Care The diet should be light and nutritious. Eat more vegetables, (such as cabbage and cauliflower, etc.) and radish, sour plum, soybean, beef, mushroom, asparagus, coix seeds, etc., foods containing anti-cancer substances, fruits, milk, turtle and other tonic foods rich in various amino acids, vitamins, proteins and easy to digest. Eat less greasy and heavy food; eat less dog meat, mutton and other warm food; eat less seafood without shells, bamboo shoots, taro and other allergy-prone “hair”; eat less drinks and snacks containing chemicals, preservatives and additives. Avoid eating too acid, too spicy, too salty, tobacco and alcohol and other stimulants.
