| Abstract: | Objective: To investigate the diagnostic efficacy of 99m Tc-MDP three-phase bone scintigraphy (TPBS) combined with C-reactive protein (CRP) for periprosthetic joint infection (PJI). Methods: The clinical data of 198 patients who underwent revision surgery of artificial joint between January 2017 and January 2024 and received TPBS examination before surgery were retrospectively analyzed. There were 77 males and 121 females with an average age of 63.74 years ranging from 24 to 92 years. There were 90 cases of hip arthroplasty and 108 cases of knee arthroplasty. PJI was diagnosed according to the 2013 American Musculoskeletal Infection Society (MSIS) standard diagnostic criteria. The sensitivity, specificity, accuracy, negative predictive value (NPV), and positive predict value (PPV) were calculated. The receiver operating characteristic (ROC) curve was used to compare the diagnostic performance of the three methods, and the area under curve (AUC) was used to evaluate the diagnostic performance. Results: According to the 2013 MSIS criteria, 116 cases were diagnosed as PJI, and the remaining 82 cases were aseptic loosening. The cases of PJI diagnosed by TPBS, CRP, and TPBS-CRP were 125, 109, and 137 respectively, and the cases of aseptic loosening were 73, 89, and 61 respectively. The sensitivity, accuracy, NPV, and PPV of TPBS-CRP combination in the diagnosis of PJI were higher than those of TPBS and CRP, but the specificity was lower than that of TPBS and CRP. ROC curve analysis further showed that the AUC value of TPBS-CRP combination was better than that of TPBS and CRP. The severity of bone defect and the duration of symptoms in patients with false positive TPBS diagnosis were worse than those in patients with true negative TPBS diagnosis ( P <0.05), but there was no significant difference in the survival time of prosthesis between the two groups ( P >0.05). Among the patients diagnosed with PJI by TPBS, CRP, and TPBS-CRP, 49, 35, and 54 patients had received antibiotic treatment 2 weeks before diagnosis, respectively. There was no significant difference in the diagnostic accuracy of TPBS and TPBS-CRP before diagnosis between patients treated with and without antibiotics and those not treated ( P >0.05). The diagnostic accuracy of antibiotic therapy before CRP diagnosis was significantly lower than that of untreated patients ( P <0.05). Conclusion: TPBS and CRP have limited specificity in differentiating PJI from aseptic loosening. The TPBS-CRP combination diagnostic method can synergize the local bone metabolic characteristics and systemic inflammatory response to achieve higher diagnostic accuracy, but caution should be exercised in patients with severe bone defects and longer symptom duration. |

[Publisher, Chinese] 回顾分析2017年1月—2024年1月行人工关节翻修手术且术前接受TPBS检查的198例患者临床资料。其中男77例，女121例；年龄24～92岁，平均63.74岁。髋关节置换90例，膝关节置换108例。根据2013年美国肌肉与骨骼感染学会（MSIS）标准诊断PJI。计算灵敏度、特异度、准确性、阴性预测值（negative predictive value，NPV）和阳性预测值（positive predict value，PPV），采用受试者工作特征（receiver operating characteristic，ROC）曲线比较3种方式的诊断效能，并以曲线下面积（area under curve，AUC）评价其诊断效能。. [Publisher, Chinese] 根据2013年MSIS标准，116例确诊为PJI，余82例为无菌性松动。TPBS、CRP、TPBS-CRP联合诊断的PJI例数分别为125、109、137例，无菌性松动分别为73、89、61例。TPBS-CRP联合诊断PJI的灵敏度、准确性、NPV和PPV均高于TPBS和CRP，但特异度低于TPBS和CRP；ROC曲线分析进一步表明，TPBS-CRP联合诊断的AUC值优于TPBS和CRP。TPBS诊断为假阳性患者的骨缺损严重程度和症状持续时间均差于真阴性患者（ P <0.05），但二者假体生存时间差异无统计学意义（ P >0.05）。采用TPBS、CRP、TPBS-CRP诊断为PJI的患者中，诊断前2周分别有49、35、54例接受过抗生素治疗，TPBS和TPBS-CRP诊断前采用抗生素治疗和未治疗的诊断准确性比较差异无统计学意义（ P >0.05）；而CRP诊断前采用抗生素治疗的诊断准确性显著低于未治疗患者（ P <0.05）。. [Publisher, Chinese] TPBS、CRP鉴别PJI和无菌性松动的特异度有限。TPBS-CRP联合诊断方法可协同局部骨代谢特征与全身炎症反应，实现更高诊断准确性；但对于严重骨缺损和症状持续时间较长的患者应谨慎考虑。. |
