Abstract
Objective To explore the etiology, diagnosis and treatment of spinal cord injury in children without fracture and dislocation , for further understanding.Methods The data of 12 children with spinal cord injury without fracture and dislocation in Shenzhen Children’s Hospital from June 2013 to December 2017 were analyzed retrospectively , including 2 boys and 10 girls, aged 3-12 years, mean age 6 years.The cause of the injury and the time of symptom onset were analyzed , and a spinal cord MR examination was performed within 24 hours after admission.The degree of spinal cord injury was grouped according to the US ASIA classification.Results The pathogenic factors in the children included 2 cases of cervical sprain , 4 cases of buttocks, 2 cases of slight trauma of the lower back, and 4 cases of improper lower back movement after dancing.After the injury, the symptoms ranged from 30 min to 48 h, and the time from the injury to the admission period ranged from 3 hours to 5 days.2 cases of cervical sprain , 1 case of cervical spinal MR examination showed no obvious abnormality , 1 case of cervical thoracic MR showed C 1 -T12 long T1 long T2 abnormal signal.Another 10 cases, 5 cases of MR examination did not see obvious abnormalities, and the other 5 cases of T4 -L5 could see different degrees of long T 1 long T2 abnormal signal.According to ASIA damage degree classification : 2 cases of grade A, 2 cases of grade B, 6 cases of grade C, 2 cases of grade D.After discharge from hospital for 6 months to 5 years, 1 case was refused, 1 case was grade A, 6 cases were grade D, and 4 cases were grade E. Conclusion Spinal cord injury without fracture and dislocation is common in children under 8 years old.There is a clear history of trauma.MR examination can improve the diagnosis of spinal cord injury without fracture and dislocation , but the conventional MR examination has a certain negative rate.Compared with conventional MRI , DTI is more sensitive to the diagnosis of spinal cord injury , and will provide a non-invasive examination method for evaluating the severity of spinal cord injury and recovery of motor function in the future.Provide a basis for the diagnosis of spinal cord injury without fracture and dislocation.关键词
