By gaining insight into the Quality of Life (QoL) status and occurrence of complications, critical facets in the care for patients with Fracture-Related Infection (FRI) can be mitigated and measures can be taken to improve their outcome. Therefore, the aims of this study were to 1) determine the QoL in FRI patients in comparison to non-FRI patients and 2) describe the occurrence of complications in both FRI and non-FRI patients. An ambidirectional cohort study was conducted in a level-1 trauma centre between January 1st 2016 and November 1st 2021. All patients who underwent surgical stabilisation of a long bone fracture were eligible for inclusion. Patients with an Injury Severity Score (ISS) ≥16 or incomplete follow-up were excluded. QoL was assessed through the use of five-level EuroQol five-dimension (EQ-5D-5L) questionnaires twelve months post-injury.Aim
Method
Fracture-Related Infection (FRI) is a severe complication caused by microbial infection of bone. It is imperative to gain more insight into the potentials and limitations of Debridement, Antibiotics and Implant Retention (DAIR) to improve future FRI treatment. The aims of this study were to: 1) determine how time to surgery affects the success rate of DAIR procedures of the lower leg performed within 12 weeks after the initial fracture fixation operation and 2) evaluate whether appropriate systemic antimicrobial therapy affects the success rate of a DAIR procedure. This multinational retrospective cohort study included patients of at least 18-years of age who developed an FRI of the lower leg within 12 weeks after the initial fracture fixation operation, between January 1st 2015 to July 1st 2020. DAIR success was defined by the absence of recurrence of infection, preservation of the affected limb and retention of implants during the initial treatment. The antimicrobial regimen was considered appropriate if the pathogen(s) was susceptible to the given treatment at the correct dose as per guideline. Logistic regression modelling was used to assess factors that could contribute to the DAIR success rate.Aims
Methods
Fracture-related infection (FRI) is treated by adequate debridement, lavage, fracture stabilization (if indicated), adequate soft tissue coverage and systemic antimicrobial therapy. Additional administration of local antibiotics (LA), placed directly in the surgical field, is thought to be beneficial for successful eradication of infection. 1) To evaluate the effect of local antibiotics on outcome in patients with FRI. 2) To evaluate whether bacterial resistance to the implanted local antibiotics influences its efficacy.Background
Aims
Fracture-related infection (FRI) is one of the most serious complications in orthopedic trauma surgery [1]. The role of Negative Pressure Wound Therapy (NPWT) remains controversial in the management pathway of FRI [2]. Currently, as scientific evidence is lacking, most recommendations for NPWT with respect to the treatment of FRI are based on expert opinion [3]. The aim of this study was to assess the influence of NPWT and its duration on recurrence of infection in operatively treated FRI patients. This is a retrospective cohort study based on the FRI database of three Level 1 Trauma Centres. To be included, patients had to be at least 16 years of age and needed to be surgically treated for FRI between January 1st 2015 and September 1st 2020. Included patients were subdivided in either the NPWT group, or in the control group, when no NPWT had been applied. To avoid confounding, patients were excluded if they (also) underwent NPWT prior to the FRI diagnosis. The relation between the duration of NPWT during FRI treatment and the recurrence rate of infection was analyzed using a multivariable logistic regression model.Aim
Methods
Fracture-related infection (FRI) is an important complication related to orthopaedic trauma. Although the scientific interest with respect to the diagnosis and treatment of FRI is increasing, data on the microbiological epidemiology remains limited. Therefore, the primary aim of this study was to evaluate the microbiological epidemiology related to FRI, including the association with clinical symptoms and antimicrobial susceptibility data. The secondary aim was to analyze whether there was a relationship between the time to onset of infection and the microbiological etiology of FRI. Over a five-year period, FRI patients treated at the University Hospitals of Leuven, Belgium, were retrospectively included. The microbiological etiology and antimicrobial susceptibility data were analyzed. Patients were classified as having an early (<2 weeks after implantation), delayed (2–10 weeks) or late-onset (> 10 weeks) FRI.Purpose
Methods
Fracture related infection (FRI) is classically defined as early (0–2 weeks), delayed (3–10 weeks) or late (>10 weeks). Treatment strategies reflect this, particularly with debridement and implant retention (DAIR), but there is little evidence to support this. This multinational study clarified the relationship between pathogens isolated and time from injury. All confirmed FRI cases, managed surgically, at three hospitals were included. Data were analyzed on patient demographics, time from injury and pathogens isolated. Patients who underwent DAIR were also analyzed separately.Aim
Methods
This study investigated the effect of the choice of antibiotic regime on outcome of patients treated for fracture-related infection (FRI) at 3 centres, in the UK and the Netherlands between 2015 and 2019. All patients with FRI, confirmed by the FRI Consensus Definition1 and treated surgically, were included. Data were collected on patient characteristics, microbial cultures, antibiograms, empiric and definitive systemic antibiotic regimes and local antibiotic use. All patients were followed up for at least one year. The primary outcome was eradication of infection. The chosen antibiotic regimes were compared to the recent guidelines from the FRI Consensus Group2, to assess the correlation with outcome.Aim
Method
Early fracture-related infections (FRIs) are a common entity in hospitals treating trauma patients. It is important to be aware of the consequences of FRI in order to be able to counsel patients about the expected course of their disease. Therefore, the aims of this study were to evaluate the recurrence rate, to establish the number of secondary surgical procedures needed to gain control of the initial infection, and to identify predictors for recurrence in patients with early FRI. A retrospective multicentre cohort study was conducted in two level 1 trauma centres. All patients between January 1st 2015 to July 1st 2020 with confirmed FRI with an onset of <6 weeks after initial fracture fixation were included. Recorded data included patient demographics, trauma mechanism, clinical and laboratory findings, surgical procedure, microbiology, and follow-up. Univariate and multivariate logistic regression analyses were performed to assess predictors for recurrent FRI.Aim
Method
This study investigated the management and clinical outcomes of patients treated for confirmed fracture-related infection (FRI) at 3 centres, in the UK and the Netherlands between 2015 and 2019. All patients with FRI, confirmed by the FRI Consensus Definition1 and treated surgically, were included. Data were collected on patient characteristics, time from injury to FRI surgery, soft tissue reconstruction, type of stabilization and use of local antibiotics. All patients were followed up for at least one year. The rates of eradication of infection and union were assessed. The associations between treatment methods, time from injury and outcomes were determined.Aim
Method
Diagnosing fracture related infections (FRI) based on clinical symptoms alone can be challenging and additional diagnostic tools such as serum inflammatory markers are often utilized. The aims of this study were 1) to determine the individual diagnostic performance of three commonly used serum inflammatory markers: C-Reactive Protein (CRP), Leukocyte Count (LC) and Erythrocyte Sedimentation Rate (ESR), and 2) to determine the diagnostic performance of a combination of these markers and their value additionally to clinical predictors for FRI. This cohort study included patients who presented with a suspected FRI at two level I academic trauma centers between February 1st 2009 and December 31st 2017. The parameters CRP, LC and ESR, were obtained from hospital records when FRI was suspected. The gold standard for diagnosing or ruling out FRI was defined as: positive microbiology results of surgically obtained tissue samples, or absence of FRI at a clinical follow-up of at least six months. Separate markers were analysed using hospital thresholds, to determine current diagnostic performance, and continuously, to determine maximum possible diagnostic performance. Multivariable logistic regression analyses were performed to obtain the discriminative performance (Area Under the Receiver Operating Characteristic, AUROC) of (1) the combined inflammatory markers, and (2) the value of these markers additional to clinical parameters.Aim
Method
Diagnosing Fracture-Related Infections (FRI) is challenging. White blood cell (WBC) scintigraphy is considered the best nuclear imaging technique to diagnose FRI; a recent study by our group found a diagnostic accuracy of 92%. However, many centers use 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) which has several logistic advantages. Whether 18F-FDG-PET/CT has better diagnostic performance than white blood cell (WBC) scintigraphy is uncertain. Therefore, we aimed: 1) to determine the diagnostic performance of 18F-FDG-PET/CT for diagnosing FRI (defined as infection following an open fracture or fracture surgery) and 2) to determine cut-off values of standardized uptake values (SUV) that result in optimal diagnostic performance. This retrospective cohort study included all consecutive patients who received 18F-FDG-PET/CT to diagnose FRI in two level 1 trauma centers. Baseline demographic- and surgical characteristics were retrospectively reviewed. The reference standard consisted of at least 2 representative microbiological culture results or the presence or absence of clinical confirmatory FRI signs in at least 6 months of clinical follow-up. A nuclear medicine specialist, blinded to the reference standard, re-reviewed all scans. Additionally, SUVs were measured using the “European Association of Nuclear Medicine Research Ltd. (EARL)” reconstructed 18F-FDG-PET/CT scans. Volume of interests were drawn around the suspected- and corresponding contralateral area to obtain the absolute values (SUVmax) and the ratio between suspected and contralateral area (SUVratio). Diagnostic accuracy of the re-reviewed scans was calculated (sensitivity and specificity). Additionally, diagnostic characteristics of the SUV measurements were plotted in the area under the receiver operating characteristics curve (AUROC). The sensitivity and specificity at the optimal threshold was deducted from the AUROC with the Q-point method.Aim
Method
White blood cell (WBC) scintigraphy for diagnosing fracture-related infections (FRIs) has only been investigated in small patient series. Aims of this study were (1) to establish the accuracy of WBC scintigraphy for diagnosing FRIs, and (2) to investigate whether the duration of the time interval between surgery and WBC scintigraphy influences its accuracy. 192 consecutive WBC scintigraphies with 99mTc-HMPAO-labelled autologous leucocytes performed for suspected peripheral FRI were included. The goldstandard was based on the outcome of microbiological investigation in case of surgery, or - when these were not available - on clinical follow-up of at least six months. The discriminative ability of the imaging modalities was quantified by several measures of diagnostic accuracy. A multivariable logistic regression analysis was performed to identify predictive variables of a false-positive or false-negative WBC scintigraphy test result.Aim
Method
Fracture related infection (FRI) remains a challenging diagnosis in orthopedic and trauma surgery. In addition to clinical signs and imaging, serum inflammatory markers are often used to estimate the probability of FRI. To what extent serum inflammatory markers can be used to rule out and diagnose FRI remains unclear. The aim of this systematic review was to assess the diagnostic value of the serum inflammatory markers C-reactive protein (CRP), leukocyte count (LC) and erythrocyte sedimentation rate (ESR) in suspected fracture related infection. PubMed, Embase and Cochrane databases were searched for all articles focusing on the diagnostic value of CRP, LC and ESR in FRI. Studies on other inflammatory markers or other types of orthopedic infection, such as periprosthetic and diabetic foot infections, were excluded. For each serum inflammatory marker, all reported sensitivity and specificity combinations were extracted and graphically visualized. Average estimates were obtained using bivariate mixed effects models. This study utilized the QUADAS-2 criteria and was reported following the PRISMA statement.Aim
