摘　　要：目的探讨DR、MSCT容积再现技术(VRT)对桡骨骨折术前诊断及术后应用价值。方法回顾分析2017年6月至2019年6月在本院骨科进行治疗的桡骨骨折100例患者的临床资料,均接受DR和MSCT检查。对患者所得图像进行分析,并对比DR和MSCT对不同类型桡骨骨折患者的检出率,分析患者骨折处掌倾角、尺偏角、桡骨高度测量情况。结果DR对Colles骨折、Smith骨折、Barton骨折诊断符合率分别为77.77%、78.12%、65.21%,明显低于MSCT检查(95.55%、96.87%、91.30%,P<0.05),在掌倾角、尺度角上,DR和MSCT检查中对比差异有统计学意义(P<0.05),但在桡骨远端高度上差异无统计学意义(P>0.05)。结论MSCT容积再现技术对桡骨骨折术前诊断及术后应用价值上优于DR检查,能更加直观地显示骨折部位情况,有助于骨折分型,为临床治疗方案选择以及术后情况评估提供重要参考。Objective To explore the preoperative diagnosis and postoperative value of DR and MSCT volume rendering technique(VRT)for radius fracture.Methods The clinical data of 100 patients with radius fracture treated in orthopedics department of our hospital from June 2017 to June 2019 were retrospectively analyzed.All patients underwent DR and MSCT.The patient’s image was analyzed,and the detection rate of DR and MSCT for patients with different types of radius fracture was compared.The measurement of the inclination angle,ulnar inclination and radius height in the fracture site were compared.Results The diagnostic accuracy of DR for Colles fracture,Smith fracture and Barton fracture was 77.77%,78.12%,and 65.21%,respectively,which was significantly lower than that of MSCT(95.55%,96.87%,and 91.30%)(P<0.05).In the dip angle and scale angle,the difference between DR and MSCT was statistically significant(P<0.05),but there was no significant difference in the distal radius of the radius(P>0.05).Conclusion MSCT volume rendering technique is superior to DR in the preoperative diagnosis and postoperative application value of radius fractures.It can display the fracture site more intuitively and contribute to fracture classification.It has important reference value for clinical treatment and postoperative evaluation.
