磁共振成像在膝关节损伤不完全性骨折诊断中的作用

Role of Magnetic Resonance Imaging in the Diagnosis of Incomplete Fracture of Knee Injury

目的:探讨磁共振成像在膝关节损伤不完全性骨折诊断中的作用。方法:选取2019年1月至2020年1月肇庆市第二人民医院收治的39例膝关节损伤不完全性骨折患者为研究对象,对39例患者的X射线检查和磁共振成像检查结果进行回顾性分析,比较两种检查方法的诊断结果。结果:X射线检查结果为患者均未检出不完全骨折图像;磁共振成像检查结果为15例患者不完全性骨折位置为胫骨外侧平台,7例患者位置为胫骨内侧平台,6例患者位置为股骨外髁,5例患者位置为股骨内髁,1例患者位置为髌骨,5例患者骨折位置有2处或以上,患者中伴有胫骨平台塌陷患者共有3例;所有患者的磁共振图像特点为全部以低信号显示T1加权像,以高信号显示T2加权像和质子加权脂肪抑制像。结论:在膝关节损伤不完全性骨折患者的临床诊断中应用磁共振检查方式,显著优于X射线,能够获得更高的检出准确性,为临床治疗提供更全面的诊断依据。

Objective To investigate the role of magnetic resonance imaging in the diagnosis of incomplete fracture of knee injury.Methods 39 patients with incomplete fracture of knee injury treated in Zhaoqing Second People's Hospital from January 2019 to January 2020 were selected as the research object.The results of X-ray examination and magnetic resonance imaging of 39 patients were analyzed retrospectively,and the diagnostic results of the two examination methods were compared.Results X-ray examination showed that no incomplete fracture images were detected in all patients;Magnetic resonance imaging showed that the location of incomplete fracture in 15 patients was the lateral tibial plateau,7 patients were the medial tibial plateau,6 patients were the lateral femoral condyle,5 patients were the medial femoral condyle,1 patient was the patella,5 patients had 2 or more fracture locations,and 3 patients had tibial plateau collapse;The MRI images of all patients were characterized by low signal T1 weighted image,high signal T2 weighted image and proton weighted fat suppression image.Conclusion The application of magnetic resonance examination in the clinical diagnosis of incomplete fracture of knee injury is significantly better than X-ray.It can obtain higher detection accuracy and provide a more comprehensive diagnostic basis for clinical treatment.
