目的:探讨64排CT扫描及多平面重建在桡骨远端骨折不同分型的诊断价值.方法:选取113例桡骨远端骨折患者作为研究对象,均进行64排CT扫描、多平面重建及关节镜检查,以关节镜手术结果作为诊断及分型的金标准.比较两种检查方式对桡骨远端骨折AO分型诊断符合率、背缘分离移位距离、骨块厚度及数目以及AO分型的诊断效能.结果:64排CT平扫对AO分型诊断符合率为70.80%,多平面重建后AO分型诊断符合率达到92.92%,高于单纯64排CT平扫(P<0.05);CT多平面重建对于背缘分离移位距离、背侧骨块的厚度和数量等方面优于64排CT平扫(P<0.05);CT多平面重建组在诊断桡骨远端骨折AO分型的诊断效能分别为:灵敏度98.15%(106/108)、特异性62.50%(5/8)、准确率93.81%(106/113)均优于64排CT平扫组[灵敏度82.98%(78/94)、特异性26.32%(5/19)、准确率73.45%(83/113)](P<0.05).结论:CT多平面重建较64排CT平扫对AO分型的诊断率更高,可更加高效地辅助临床医生进行AO分型.
Diagnostic Value of 64-Slice CT Scanning and Multiplanar Reconstruction in Different Types of Distal Radius Fractures
Objective:To explore the diagnostic value of 64-slice CT scanning and multiplanar reconstruction in different types of distal radius fractures.Methods:113 patients with distal radius fractures were selected as the research object,all of them underwent 64-slice CT scanning,multiplanar reconstruction and arthroscopy,and the results of arthroscopy were taken as the gold standard for diagnosis and classification.The coincidence rate,distance of distal edge separation,thickness and number of bone fragments and diagnostic efficiency of AO classification of distal radius fractures were compared between the two methods.Results:The accuracy of 64-slice CT plain scan was 70.80%,and the accuracy of 64-slice CT plain scan was 92.92% after multi-plane reconstruction,which was higher than that of 64-slice CT plain scan (P<0.05).CT multi-plane reconstruction was superior to 64-slice CT plain scan in terms of dorsal border separation and displacement distance,thickness and quantity of dorsal bone mass (P<0.05).The diagnostic efficacy of multi-plane CT reconstruction group in the diagnosis of AO classification of distal radius fractures were as follows:The sensitivity 98.15% (106/108),specificity 62.50% (5/8) and accuracy 93.81% (106/113) were superior to the 64-slice CT plain scan group[sensitivity 82.98% (78/94),specificity 26.32% (5/19),accuracy 73.45% (83/113)](P<0.05).Conclusion:Compared with 64-slice CT plain scan,CT multiplanar reconstruction has a higher diagnostic rate for AO classification,which can better and efficiently assist clinicians in AO classification.
