    Abstract:
    BACKGROUND: Labeled leukocyte scintigraphy (LS) is considered a valuable tool in preoperative diagnosis of prosthetic joint infections (PJI). The aim of this study was to determine the accuracy of LS combined with bone marrow scintigraphy (BMS), as well as inflammation markers CRP and WBC, in detecting infection in patients with prosthetic joints. MATERIAL AND METHODS: This study included patients suspected of having PJI between January and September 2013 at the Vienna General Hospital who underwent imaging with 99mTc-HMPAO labeled autologous leukocytes and subsequent BMS. Diagnostic accuracy was assessed in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS: A total of 48 patients were included. The most common joint investigated was knee (25), followed by hip (9), shoulder (2), and elbow (1). Other parts of the body investigated included the femur (6), tibia (2), leg (2), and foot (1). The pathogens most frequently isolated included Staphylococcus epidermidis and Candida albicans. The sensitivity of LS was 60%, specificity 97%, PPV 86% and NPV 90%. Overall accuracy was calculated to be 90%. CONCLUSIONS: This study was able to demonstrate that 99mTc-HMPAO labeled autologous leukocytes in patients presenting with symptoms of PJI is accurate. In contrast, however, inflammation markers CRP and WBC are not accurate pre-diagnostic markers for PJI.
