摘要
目的探讨X线平片与多层螺旋CT(MSCT)三维重建在桡骨远端骨折诊断中的价值。方法回顾性分析本院2016年2月至2018年11月收治的200例桡骨远端骨折患者临床资料,所有患者均先后X线平片与MSCT三维重建检查,比较X线平片与MSCT三维重建诊断结果差异。结果本研究200例患者中,X线平片共确诊桡骨远端骨折182例,其中A型94例,B型18例,C型70例;MSCT三维重建确诊的200例患者中包括A型23例,B型21例,C型156例,X线平片和MSCT三维重建检查桡骨远端骨折AO分型结果比较(P<0.05);X线平片与MSCT三维重建诊断A型、B型、C型一致性Kappa值分别为0.256、0.233、0.264,一致性程度一般(P<0.05);MSCT三维重建检测骨块数目多于X线平片,背侧缘分离移位与冠状面桡腕关节塌陷距离大于X线平片(P<0.05);MSCT三维重建与X线平片检测背侧骨块厚度结果比较(P>0.05)。结论MSCT相对X线可诊断隐匿性骨折,在复杂性骨折准确分型上具有明显的优势,在明确骨折信息方面更精准。
Objective To explore diagnostic value of X-ray films and multi-slice spiral CT(MSCT)threedimensional reconstruction in distal radius fractures.Methods The clinical data of 200 patients with distal radius fractures who were admitted to the hospital from February 2016 to November 2018 were retrospectively analyzed.All patients underwent X-ray films and MSCT three-dimensional reconstruction examination.The difference in diagnostic results between X-ray films and MSCT threedimensional reconstruction were compared.Results Of 200 patients in the study,there were 182 cases confirmed with distal radius fractures by X-ray films,including 94 cases with type A,18 cases with type B and 70 cases with type C.Among the 200 patients confirmed by MSCT three-dimensional reconstruction,there were 23 cases,21 cases and 156 cases with type A,B and C,respectively.There were significant differences in diagnostic results of distal radius fractures AO typing between X-ray films and MSCT three-dimensional reconstruction(P<0.05).The consistency Kappa values between X-ray films and MSCT three-dimensional reconstruction for diagnosis of type A,B and C were 0.256,0.233 and 0.264,respectively.The consistency degree was general(P<0.05).The number of bone fragments detected by MSCT three-dimensional reconstruction was more than that by X-ray films,separation shifting distance of margo dorsalis,and collapse distance of coronal radiocarpal joint were greater than those by X-ray films(P<0.05).There was no significant difference in detection results of dorsal bone thickness between MSCT three-dimensional reconstruction and X-ray films(P>0.05).Conclusion Compared with X-ray films,MSCT can diagnose occult fractures,which is of significant advantages in accurately determining complex fractures typing.It is more accurate in determining fracture information.
