The Application of X-ray and 3D CT Imaging in Evaluation of Tibial Plateau Fracture
-
摘要: 目的:通过比较X线平片与三维CT检查对胫骨平台骨折损伤评价的信度和效度,探讨X线平片与CT检查的应用价值。方法:回顾性分析2015年1月至2016年1月间收治的32例胫骨平台骨折损伤的病例,分别使用X线平片和三维CT检查对骨折损伤程度及部位做出判断,对骨折特征进行分析,对结果的效度进行判断(金标准为手术记录所描述),并用Mc Nemar检验比较X线平片和三维CT判断结果。结果:胫骨平台骨折三维CT重建在外柱诊断优于X线平片(P=0.031),对骨折分型具有更高临床价值。结论:使用三维CT检查能够提高对胫骨平台骨折损伤评价的可靠性和准确性,可更好指导诊断及治疗方案的制订。Abstract: Objective: To make comparison between the reliability and validity of both X-ray and 3D(three-dimensional) CT imaging inevaluation of Tibial plateau fracture, and to discuss the application of the X-ray and 3D CT examination. Methods: Analyzed retrospectively 32 cases of Tibial plateau fracture who were hospitalized from January 2015 to January 2016. X-ray and 3D CT imaging were respectively used to judge the fracture type and characteristics, Analyze the standard validity of the facture judgment results(the operation record description was used as the gold standard). The differences between the X-ray and 3D CT judgment results and the gold standard were compared by Mc Nemar test. Results: The diagnosis of external column with 3D CT was significantly higher than that of X-ray results(P=0.031). Conclusion: The 3D CT examination can increase the reliability and accuracy of the evaluation of tibial plateau fracture, and is helpful to guide the diagnosis and the determination of operation schedule.
