摘要
目的:探讨常规CT平扫与多平面重建技术在桡骨远端骨折分型中的诊断价值。方法:回顾性分析2022年1月—2024年1月平原县第一人民医院收治的86例桡骨远端骨折患者的临床资料。所有患者均已行常规CT平扫及多平面重建技术。统计AO分型检出情况,并以关节镜手术检查为金标准,分析不同方法的诊断价值;比较不同方法检出关节内骨块数目、背侧骨块厚度、背缘分离移位距离差异。结果:86例患者经关节镜手术检查检出阳性30例(A型),阴性56例(B型36例+C型20例);其中常规CT平扫检出阳性26例(A型),阴性60例(B型35例+C型25例);多平面重建技术检出阳性29例(A型),阴性57例(B型36例+C型21例)。多平面重建技术诊断桡骨远端骨折分型的灵敏度、准确度高于常规CT平扫,差异有统计学意义(P<0.05)。多平面重建技术检出关节内骨块数目、背侧骨块厚度、背缘分离移位距离为(1.94±0.29)个、(1.82±0.26)mm、(1.67±0.28)mm,优于常规CT平扫的(1.42±0.22)个、(1.47±0.24)mm、(1.12±0.19)mm,差异均有统计学意义(P<0.05)。结论:多平面重建技术诊断桡骨远端骨折分型的价值更高,可于术前精准识别疾病分型,便于制定手术方案。
Objective:To evaluate the diagnostic value of conventional CT plain scan and multiplanar reconstruction in the classification of distal radius fractures.Methods:The clinical data of 86 patients with distal radius fracture admitted to our hospital from January 2022 to January 2024 were retrospectively analyzed.Conventional CT plain scan and multi-plane reconstruction techniques were used to analyze the AO typing and the diagnostic value of different methods was analyzed using arthroscopic surgery as the gold standard.The number of intra-articular bone mass,the thickness of dorsal bone mass,and the separation and displacement distance of dorsal margin were compared between different methods.Results:Out of 86 patients,30 were positive(type A)and 56 were negative(36 were type B and 20 were type C)detected through arthroscopic surgery;Among them,26 cases were detected as positive(type A),and 60 cases were negative(35 cases of type B+25 cases of type C)by routine CT plain scan;Multi plane reconstruction technology detected 29 positive cases(type A)and 57 negative cases(36 cases of type B+21 cases of type C)The sensitivity and accuracy of multi-plane reconstruction in the diagnosis of distal radius fracture were higher than that of conventional CT,with statistical difference(P<0.05).The number of bone fragments in the joint,the thickness of the dorsal bone fragments,and the separation and displacement distance of the dorsal border were(1.94±0.29),(1.82±0.26)mm,(1.67±0.28)mm,respectively,which were better than(1.42±0.22),(1.47±0.24)mm,(1.12±0.19)mm of conventional CT plain scan,and there were statistical differences(P<0.05).Conclusion:The multi-plane reconstruction technique is more valuable in the diagnosis of distal radius fracture classification,which can accurately identify the disease classification before surgery,better formulate the surgical plan.
