Infection of the musculoskeletal (MSK) system is a dreaded complication that seems to be on the rise. Many factors, such as resistant bacteria or poor host factors, may influence such rise. This increase leads to greater resource consumption, especially due to antibiotic (ATB) prescription. Strategies must be created to detect patients at risk and prevent such infections. Hospital administrators should be made aware of the costs and impact of MSK infections in order to understand the need to prevent such complications. Therefore, our goal is to characterize the infected orthopaedic patient and evaluate the cost associated with ATB prescription in such cases. This is a retrospective and descriptive study, based on patient record analysis of all patients treated at our department, from January 2013 to March 2015. We identified 177 patients with a MSK infection and an isolated infectious agent. There was no predominance of either sex. Approximately 50% of patients were aged between 66 and 85 years old. Most frequent agents were MSSA (30,2%) and MRSA (21,8%), followed by Streptococcus species (8,9%) and Pseudomonas aeruginosas (7,1%). Although most patients were infected by a single agent, 18,6% had two or more causative agents isolated in cultures. Of those, 69,7% had either MSSA or MRSA as one of the isolated agents. Most commonly affected area was the hip (39,5%), followed by the knee (23,2%) and ankle (21,5%). Nearly all patients had had prior surgery, with arthroplasty and osteosynthesis as the most common procedures (52,4% and 33,3%, respectively). Infection related admission was responsible for a total of 6.116 hospital bed-days, with the majority of patients staying in hospital for up to 30 days (77,3%). Total cost of hospital ATB administration was 61.365,61€, with approximately 346,7€ spent in each patient. This corresponds to 42,6% of the total cost of medication during hospital stay (144.146,1€ of total cost, with 814,4€ per patient). The typical infected orthopaedic patient is aged 66 to 85 years old, was operated to his hip or knee, and either an arthroplasty or osteosynthesis was performed. Staphylococcus aureus remains the most common agent. MSK infections have significant costs associated with their treatment, and clinical departments should periodically re-evaluate discharged patients in order to understand what groups are at risk of developing such a complication. Only a correct identification of all these factors makes it possible to create a targeted preventive strategy, in order to reduce costs to the institution.
Accurate diagnosis of peri-prosthetic joint infection is critical to allow adequate treatment. Currently, the criteria of the Musculo-Skeletal Infection Society (MSIS) serve as a validated reference tool. More recently, these criteria have been modified for better accuracy. The goal of this study was to compare retrospectively the diagnostic accuracy of these two different tools in cases of known peri-prosthetic hip or knee infection or in aseptic cases and to analyze one additional criterion: presence of an early loosening (prior to 2 years after implantation). All cases of hip or knee prosthesis exchange operated on at our department during the year 2017 have been selected. There were 130 cases in 127 patients: 67 men and 60 women, with a mean age of 69 years − 69 total hip (THA) and 61 total knee (TKA) arthroplasties. 74 cases were septic and 53 cases were aseptic. All criteria included in both classifications were collected: presence of a fistula, results of bacteriological samples, ESR and CRP levels, analysis of the joint fluid, histological analysis. Additionally, the presence of an early loosening was recorded. The diagnosis accuracy of the classical MSIS classification and of the 2018 modification were assessed and compared with a Chi-square test at a 0.05 level of significance.Introduction

Aims. The aim of this paper was to present the clinical features of
patients with musculoskeletal sources of methicillin-sensitive Staphylococcus
aureus (MSSA) septicaemia. Patients and Methods. A total of 137 patients presented with MSSA septicaemia between
2012 and 2015. The primary source of infection was musculoskeletal
in 48 patients (35%).
High-energy injuries can result in multiple complications, the most prevalent being infection. Vancomycin powder has been used with increasing frequency in orthopaedic trauma given its success in reducing infection following spine surgery. Additionally, large, traumatic injuries require wound coverage and management by dressings such as negative pressure wound therapy (NPWT). NPWT has been shown to decrease the ability of antibiotic cement beads to reduce infection, but its effect on antibiotic powder is not known. The goal of this study was to determine if NPWT reduces the efficacy of topically applied antibiotic powder. Complex musculoskeletal wounds were created in goats and inoculated with a strain of Aims
Methods
We compared the use of broth culture medium for
samples taken in theatre with the standard practice of placing tissue
samples in universal containers. A total of 67 consecutive patients
had standard multiple samples of deep tissue harvested at surgery
and distributed equally in theatre either to standard universal
containers or to broth culture medium. These samples were cultured
by direct and enrichment methods. The addition of broth in theatre to
standard practice led to an increase in sensitivity from 83% to
95% and an increase in negative predictive value from 77% to 91%.
Placing tissue samples directly into broth in the operating theatre
is a simple, inexpensive way to increase the sensitivity of cultures
from infected patients, and does not appear to compromise the specificity
of these cultures. Cite this article:
Aim.
To date, few studies have investigated the feasibility of the loop-mediated isothermal amplification (LAMP) assay for identifying pathogens in tissue samples. This study aimed to investigate the feasibility of LAMP for the rapid detection of methicillin-susceptible or methicillin-resistant Staphylococcus aureus (MSSA or MRSA) in tissue samples, using a bead-beating DNA extraction method. Twenty tissue samples infected with either MSSA (n = 10) or MRSA (n = 10) were obtained from patients who underwent orthopedic surgery for suspected

Aims. Total femoral arthroplasty (TFA) is a rare procedure used in cases of significant femoral bone loss, commonly from cancer, infection, and trauma. Low patient numbers have resulted in limited published work on long-term outcomes, and even less regarding TFA undertaken for non-oncological indications. The aim of this study was to evaluate the long-term clinical outcomes of all TFAs in our unit. Methods. Data were collected retrospectively from a large tertiary referral revision arthroplasty unit’s database. Inclusion criteria included all patients who underwent TFA in our unit. Preoperative demographics, operative factors, and short- and long-term outcomes were collected for analysis. Outcome was defined using the

Aims. The duration of systemic antibiotic treatment following first-stage revision surgery for periprosthetic joint infection (PJI) after total hip arthroplasty (THA) is contentious. Our philosophy is to perform an aggressive debridement, and to use a high local concentration of targeted antibiotics in cement beads and systemic prophylactic antibiotics alone. The aim of this study was to assess the success of this philosophy in the management of PJI of the hip using our two-stage protocol. Methods. The study involved a retrospective review of our prospectively collected database from which we identified all patients who underwent an intended two-stage revision for PJI of the hip. All patients had a diagnosis of PJI according to the major criteria of the
