X线、CT及MRI在行髋关节置换治疗术后并发症诊断中的价值分析

Value Analysis of X-ray, CT and MRI in the Diagnosis of Complications After Hip Replacement

目的探究X线、CT及MRI对髋关节置换术(HR)术后并发症的诊断价值。方法选择2019年1月-2022年4月吉水县人民医院行HR治疗,且经病理学检查确定存在术后并发症的150例患者,采用随机数字表法分为X线组(50例)、CT组(50例)与MRI组(50例),分别行X线、CT、MRI检查,比较3组HR术后并发症检出率,包括假体周围感染、骨溶解、假体周围感染与假体周围骨折,分析X线、CT、MRI对HR术后并发症的诊断敏感性、特异性、准确率,对比3种检测方式的总体准确率。结果髋关节脱位、假体周围骨折的检出率由高至低依次为X线组>MRI组>CT组(P<0.05),骨溶解的检出率由高至低依次为CT组>MRI组>X线组(P<0.05),假体周围感染的检出率由高至低依次为MRI组>CT组>X线组(P<0.05);X线对髋关节脱位、假体周围骨折的诊断敏准确率高于其他并发症,CT对骨溶解的诊断准确率、敏感性高于其他并发症,MRI对假体周围感染的诊断准确率、敏感性高于其他并发症(P<0.05);MRI对HR术后并发症的总体准确率、敏感性高于X线、CT(P<0.05)。结论X线、CT、MRI在HR术后并发症诊断中具有确切作用,其检测优势各不相同,MRI诊断价值相对较高。

Objective To explore the diagnostic value of X-ray,CT and MRI in postoperative complications of hip replacement(HR).Methods From January 2019 to April 2022,150 patients who underwent HR treatment in Jishui County People's Hospital and were confirmed to have postoperative complications by pathological examination were selected.They were divided into X-ray group(50 patients),CT group(50 patients)and MRI group(50 patients) by random number table method.X-ray,CT and MRI were performed respectively.The detection rates of postoperative complications of HR in the three groups were compared,including periprosthetic infection,osteolysis,periprosthetic infection and periprosthetic fracture.The diagnostic sensitivity,specificity and accuracy of X-ray,CT and MRI for postoperative complications of HR were analyzed,and the overall accuracy of the three detection methods was compared.Results The detection rates of hip dislocation and periprosthetic fractures from high to low were X-ray group>MRI group>CT group(P<0.05),and the detection rate of osteolysis from high to low was CT group>MRI group>X-ray group(P<0.05),the detection rate of periprosthetic infection from high to low was MRI group>CT group>X-ray group(P<0.05).The diagnostic sensitivity and accuracy of fractures were higher than those of other complications(P<0.05),the diagnostic accuracy of CT for osteolysis was higher than that of other complications(P<0.05),and the diagnostic accuracy of MRI for periprosthetic infection was higher than that of other complications symptoms(P<0.05).The overall accuracy of MRI for HR postoperative complications was higher than that of X-ray and CT(P<0.05).Conclusion X-ray,CT and MRI have definite roles in the diagnosis of postoperative complications of HR,their detection advantages are different,and the diagnostic value of MRI is relatively high.
