Aims. In the UK, the NHS generates an estimated 25 megatonnes of carbon dioxide equivalents (4% to 5% of the nation’s total carbon emissions) and produces over 500,000 tonnes of waste annually. There is limited evidence demonstrating the principles of sustainability and its benefits within orthopaedic surgery. The primary aim of this study was to analyze the environmental impact of orthopaedic surgery and the environmentally sustainable initiatives undertaken to address this. The secondary aim of this study was to describe the barriers to making sustainable changes within orthopaedic surgery. Methods. A literature search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines through EMBASE, Medline, and PubMed libraries using two domains of terms: “orthopaedic surgery” and “environmental sustainability”. Results. A total of 13 studies were included in the final analysis. All papers studied the environmental impact of orthopaedic surgery in one of three areas: waste management, resource consumption, and carbon emissions. Waste segregation was a prevalent issue and described by nine studies, with up to 74.4% of hazardous waste being generated. Of this, six studies reported recycling waste and up to 43.9% of waste per procedure was recyclable. Large joint arthroplasties generated the highest amount of recyclable waste per procedure. Three studies investigated carbon emissions from intraoperative consumables, sterilization methods, and through the use of telemedicine. One study investigated water wastage and demonstrated that simple changes to practice can reduce water consumption by up to 63%. The two most common barriers to implementing environmentally sustainable changes identified across the studies was a lack of appropriate infrastructure and lack of education and training. Conclusion. Environmental sustainability in orthopaedic surgery is a growing area with a wide potential for meaningful change. Further research to cumulatively study the carbon footprint of orthopaedic surgery and the wider impact of environmentally sustainable changes is necessary.

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
