Prosthetic joint infection (PJI) and aseptic loosening in total hip arthroplasty (THA) can present with pain and osteolysis. The Musculoskeletal Infection Society (MSIS) has provided criteria for the diagnosis of PJI. The aim of our study was to analyze the utility of F18-fluorodeoxyglucose (FDG) positron emission tomography (PET) CT scan in the preoperative diagnosis of septic loosening in THA, based on the current MSIS definition of prosthetic joint infection. A total of 130 painful unilateral cemented THAs with a mean follow-up of 5.17 years (Aims
Patients and Methods
Fluorodeoxuglucose(FDG) Positron Emission Tomography(PET) scan is used in the diagnosis of prosthetic joint infection, when the inflammatory markers and aspiration of the joint do not establish a definitive diagnosis. The aim of our study was to analyse the utility of FDG PET scan in decision making in these patients. We performed a prospective study of patients who underwent a FDG PET scan for suspected prosthetic hip infection, between September 2013 and July 2017. We analysed the results of aspiration, culture and sensitivity, histology of intra-operative samples and inflammatory markers. Our gold standard for diagnosis of infection was 3 or more positive cultures of the same organism. Diagnostic utility statistics for FDG PET were performed.Introduction
