چکیده (انگلیسی):

Purpose: Periprosthetic infection is one of the main reasons for revision surgery after hip arthroplasty.
The purpose of the present study is to compare the reliability of triple-phase bone scintigraphy (TPBS) in
the diagnosis of periprosthetic infection between cementless total hip arthroplasty (THA) and bipolar
hemiarthroplasty (BHA).
Methods: In this retrospective study, 52 patients were analyzed; 33 of them were performed with THA
and 19 of them were performed with BHA. The exclusion criteria were cementation in previous surgery,
romatological joint disorders, periprosthetic fracture and malignancy history. C reactive protein (CRP)
and erythrocyte sedimentation (ESR) rate results were recorded preoperatively. Tissue samples from the
different areas periprosthetic tissue were obtained for histopathological examination and sample tissue
culture.
Results: In the present study, the sensitivity, specificity and accuracy were 90.9%, 77.3% and 81.8%,
respectively, for THA and 77.8%, 60.0% and 68.4%, respectively, for BHA. Positive predictive values for THA
and BHA were 66.7% and 63.6%, and negative predictive values were 94.4% and 75.0%, respectively.
Conclusions: Due to the higher sensitivity, specificity and accuracy, TPBS has a more reliable diagnostic
value for cementless THA in the diagnosis of periprosthetic infection compared to cementless BHA.
