Application of the real-time monitoring with ultrasonography in the vertebral and spinal cord operation / 中华医学超声杂志（电子版）

ABSTRACT

Objective To explore the value of monitoring in vertebral and spinal cord operation by the real-time monitoring of the spinal cord in the process of operation.Methods Nineteen cases were included by the real-time monitoring of spinal cord in the process of operation.Japanese Orthopaedic Association(JOA) score was used to evaluate the clinical efficacy during following-up before and discharge after operation,6 months and 12 months after operation.Results Intraoperative ultrasound monitoring in the 19 patients had no symptom of spinal cord injury and other complications within the plant without loosening fracture occurred were bony fusion; the average JOA scores in the patients before operation,discharge after operation,6 months and 12 months after operation were 8.80±1.60,14.00±1.57,14.60±1.61 and 14.80±1.58,respectively.The improvement rate of JOA score for discharge after operation,6 months and 12 months after operation were individually 51.6%,61.3%,and 64.5%.The JOA score after operation was obviously higher than that before operation.The significant difference between the two groups was observed in the experiment (P<0.05).The cervical spinal canal sagittal diameter significantly increased after operation (mean sagittal diameter of the expansion of 6.6 mm),compared with that before the trial (P<0.05).Conclusion The real-time monitoring with ultrasonography during operation can identify the change of spinal cord and provide the image evidence of operative efficiency to avoid the injury in vertebral and spinal cord operation.
