Infection in prosthesis surgery is very dangerous because it changes the patient's prognosis. Differential diagnosis between septic and aseptic loosening is fundamental in order to apply the correct treatment. The correct diagnostic approach is still debated in literature. The aim of this study was to perform a review of literature evaluating positron emission tomography (PET) capacity to distinguish between septic and aseptic loosening in hip prosthesis. Research was done principally among medical archives. Five studies were selected which satisfied the required characteristics, and a weighted average of sensitivity and specificity of the different studies was determined. The fluorodeoxyglucose positron emission tomography (FDG-PET) sensitivity in individuating hip prosthesis infections was 82.8% and specificity was 87.3%. Positron emission tomography based on 2-fluoro-2-deoxy-D-glucose could be a valid option if research is able to find an uptake pattern specific for septic and aseptic loosening.

Introduction: Folate receptors (FR) have been considered a convenient target for different radiopharmaceuticals in recent years. Multifarious Ga-labeled folate conjugates have been proposed as promising agents for the PET imaging of FR-overexpressing malignant neoplasms. In addition, radiolabeled folate-based conjugates can be effective for imaging non-tumor pathological foci characterized by a pronounced cluster of activated macrophages.

Introduction: During revision surgery for the management of patients presenting with long-bone upper extremity nonunion, it is crucial to rule out fracture-related infection (FRI). This is especially true if there are clinical signs suggestive of FRI, or if there is a history of prior FRI, open wound fracture, or surgery. This study aimed to determine the efficacy of frozen section analysis (FSA) in providing real-time diagnosis of FRI in patients with upper-limb long-bone nonunion undergoing revision surgery.

Treatment algorithms for fracture nonunion depend on the presence or absence of bacterial infection. However, it is often impossible to identify infection preoperatively. While some infections may present with clinical signs of infection, low-grade infections lack infection signs and have a clinical presentation similar to aseptic nonunion.

The rising frequency of intra-articular procedures such as joint aspirations and injections has led to increased concern regarding iatrogenic septic arthritis. This mini-review aims to summarize current understanding of the incidence, risk factors, bacterial etiology, and strategies for preventing SA associated with intra-articular procedures.

Intramedullary nail fixation is a routine procedure for treatment of intertrochanteric fractures. Aseptic technique is vital for reducing postoperative complications, as intraoperative glove perforations increase the risk of surgical site infections. The aim of this study was to determine the incidence of surgical glove perforation during intramedullary nailing of intertrochanteric fractures and to identify surgery-specific steps at risk.
