目的 研究64排螺旋CT三维重 建在胫骨平台骨折患者诊治中的应用价 值。方法 选取我院2013年5月至2016年5 月76例拟诊为胫骨平台骨折患者为研究 对象，所有患者均行64排螺旋CT扫描检 查并接受手术治疗。分析64排螺旋CT三 维重建诊断胫骨平台骨折的灵敏度、特 异度、阳性预测值、阴性预测值、准确 性，以及胫骨平台骨折分型准确性。结 果 64排螺旋CT三维重建诊断胫骨平台骨 折的准确率为准确率为97.4%，Kappa值 为0.65。64排螺旋CT三维重建诊断胫骨 平台骨折分型的分型准确率为81.6%， Kappa值为0.76。结论 64排螺旋CT三维 重建在胫骨平台骨折诊断与分型方面具 有较高准确性，对手术方案制定具有重 要指导作用。

Objective To study the value of 64 slice spiral CT three-dimensional (3D) reconstruction in the diagnosis and treatment of tibial plateau fractures. Methods A total of 76 patients with tibial plateau fractures who were admitted to the hospital between May 2013 and May 2016 were enrolled in the study. All patients underwent 64 slicespiral CT scan and underwent surgical treatment. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 64 slice spiral CT 3D reconstruction in the diagnosis of tibial plateau fractures were analyzed. Results The accuracy of 64 slice spiral CT 3D reconstruction in the diagnosis of tibial plateau fractures was 97.4% (Kappa=0.76). The accuracy of 64 slice spiral CT 3D reconstruction in the diagnosis of types of tibial plateau fractures was 81.6% (Kappa=0.76). Conclusion The accuracy of 64 slice spiral CT 3D reconstruction in the diagnosis and typing of tibial plateau is high accuracy, which is of important guiding value in the selection of surgical procedures.
