骶骨骨折合并骶神经损伤的MRI诊断及临床应用分析

An analysis of MRI diagnosis and clinical application of sacral fracture complicated with sacral nerve injury

目的:分析骶骨骨折合并骶神经损伤的MRI诊断及临床应用效果。方法:在本院进行治疗的骶骨骨折合并骶神经损伤患者中抽取60例作为研究对象,收治时间为2015年9月-2017年9月。根据诊断方式(CT检测与MRI检测)的不同,将其分为两组,其中包括CT组、MRI组。对比两组患者的诊断结果,并与手术病理结果进行对比分析。结果:MRI检测发现,检出神经根受推压移位、神经根中断、骨折处液体量增加、神经根水肿增粗、骨折周围血肿分别占11例、14例、13例、11例、7例,与手术病理结果相比,诊断符合率为93.33%(56/60)。CT组中,其诊断符合率为80.00%(48/60)。MRI组明显高于CT组,P<0.05。结论:对于骶骨骨折合并骶神经损伤,采用MRI进行诊断,可提高诊断准确率,为临床治疗提供有效依据。

Objective： To analyze MRI diagnosis and clinical application of sacral fracture complicated with sacral nerve injury. Methods： Sixty cases of sacral fracture complicated with sacral nerve injury were selected from our hospital from September 2015 to September 2017. According to the difference between CT and MRI, the patients were divided into CT group and MRI group. The diagnostic results, the results of surgery and pathology of two groups were compared. Results： MRI showed that the nerve root was displaced, the nerve root interrupted, the volume of fluid at the fracture increased, the nerve root edema increased and the hematoma around the fracture accounted for 11 cases, 14 cases, 13 cases and 7 cases, respectively. Compared with the results of surgery and pathology, the diagnostic accordance rate was 80.00%（48/60）; MRI group was significantly higher than CT group, P〈0.05. Conclusion： The diagnosis of sacral fracture combined with sacral nerve injury by MRI could improve the accuracy of diagnosis, provide effective basis for clinical treatment.
