The aim of this study was to perform the first population-based description of the epidemiological and health economic burden of fracture-related infection (FRI). This is a retrospective cohort study of operatively managed orthopaedic trauma patients from 1 January 2007 to 31 December 2016, performed in Queensland, Australia. Record linkage was used to develop a person-centric, population-based dataset incorporating routinely collected administrative, clinical, and health economic information. The FRI group consisted of patients with International Classification of Disease 10th Revision diagnosis codes for deep infection associated with an implanted device within two years following surgery, while all others were deemed not infected. Demographic and clinical variables, as well as healthcare utilization costs, were compared.Aims
Methods
The aim of this study was to evaluate the diagnostic value of preoperative serum CRP, white blood cell count (WBC), percentage of neutrophils (%N), and neutrophil to lymphocyte ratio (NLR) when using the fracture-related infection (FRI) consensus definition. A cohort of 106 patients having surgery for suspected septic nonunion after failed fracture fixation were studied. Blood samples were collected preoperatively, and the concentration of serum CRP, WBC, and differential cell count were analyzed. The areas under the curve (AUCs) of diagnostic tests were compared using the z-test. Regression trees were constructed and internally cross-validated to derive a simple diagnostic decision tree.Aims
Methods
This study aimed to investigate the role of quantitative histological
analysis in the diagnosis of fracture-related infection (FRI). The clinical features, microbiology culture results, and histological
analysis in 156 surgically treated nonunions were used to stratify
the likelihood of associated infection. There were 64 confirmed
infected nonunions (one or more confirmatory criteria: pus, sinus,
and bacterial growth in two or more samples), 66 aseptic nonunions
(no confirmatory criteria), and 26 possibly infected nonunions (pathogen
identified from a single specimen and no confirmatory criteria).
The histological inflammatory response was assessed by average neutrophil
polymorph (NPs) counts per high-power field (HPF) and compared with
the established diagnosis.Aims
