X片和CT三维重建诊断老年人踝关节骨折的价值观察

Value of X-ray And CT Three-dimensional Reconstruction in The Diagnosis of Ankle Fractures in The Elderly

目的 探究X片和CT三维重建诊断老年人踝关节骨折的价值。方法 回顾性分析2015年8月至2019年8月于我院收治的98例老年踝关节骨折患者临床资料,患者术前均行X线、CT三维重建,且均行手术治疗并判断患者骨折分型。分析比较X线、CT三维重建骨折类型诊断结果 差异,比较两种影像学检查方法 误诊漏诊情貌差异。结果 CT三维重建诊断骨折分型中单纯外踝骨折、单纯内踝骨折、三踝骨折准确率均高于X线(P均<0.05),诊断双踝骨折准确率差异不显著(P均<0.05);CT三维重建检查误诊、漏诊率均低于X线检查(P均<00.5)。结论 CT三维重建对老年躁关节骨折患者的诊断价值高于X线,为患者临床治疗提供了影像学依据。

Objective To explore the value of X-ray and CT three-dimensional reconstruction in the diagnosis of ankle fractures in the elderly.Methods The clinical data of 98 elderly patients with ankle fractures admitted to our hospital from August 2015 to August 2019 were retrospectively analyzed.All patients underwent X-ray and CT three-dimensional reconstruction before surgery,and all underwent surgical treatment to determine the fractu re types.Diagnostic results of fractu re types of X-ray and CT threedimensional reconstruction were analyzed and compared,and the differences in misdiagnosis and missed diagnosis were compared betweenthe two imaging examination methods.Results The accura cy rates of CT three-dimensional reconstruction in the fracture types of simple lateral malleolus fractures,simple medial malleolus fractures and trimalleolar fractures were higher than those of X-ray(all P<0.05),and there was no significant difference in the accuracy rate of diagnosing bimalleolar anklefractures(P<0.05).The rates of misdiagnosis and missed diagnosis of CT three-dimensional reconstruction examination were lower than those of X-ray(all P<0.05).Conclusion CT threedimensional reconstruction has higher diagnostic value than X-ray in the diagnosis of elderly patients with ankle fractures,and it can provide imaging basis for the clinical treatment of patients.
