摘　　要：目的:探讨CT、MRI在胫骨平台骨折临床诊断及AO分型中的应用效果。方法:对67例胫骨平台骨折患者临床资料进行回顾性分析。所有患者均给予CT及MRI医学影像检查,之后经外科手术证实为胫骨平台骨折。记录所有患者CT、MRI诊断及AO分型结果,与手术确诊结果进行对比后给予统计学分析并得出结论。结果:CT符合率仅为73.13%,显著低于MRI符合率95.52%(P<0.05);两种方法 C1型、C3型检出率差别较大(P<0.05),其他AO分型CT、MRI检出率对比结果无显著性差异(P>0.05)。结论:应用MRI检查胫骨平台骨折符合率略高于CT检查,临床医生应准确掌握胫骨平台骨折特征,对疑似病例及时给予医学影像检查,尽快确诊病情并制定针对性的治疗方案,保障患者疗效及预后。Objective： To investigate the CT and MRI application in clinical diagnosis of tibial plateau fractures and AO classification. Methods： 67 cases of tibial plateau fracture were retrospectively analysed. Recorded the CT and MRI reports and AO classification results before the operation,and which were compared with surgical operation results; and there was a statistically analysis. Results： CT correct rate was 73. 13% and was significantly lower than MRI correct rate of 95. 52%（ P 0. 05）; both methods type C1,C3- type detection rates was difference greatly（ P 0. 05）,in other AO classification CT with MRI contrast detection rate were not significantly difference（ P 0. 05）. Conclusion： MRI correct rate of tibial plateau fractures is higher than CT correct rate,the clinician should accurately grasp the characteristics of tibial plateau fractures; for suspected cases,should have imaging examination,diagnosis of the disease is as soon as possible and is targeted efficacy therapy for good prognosis.
