Objectives. Vancomycin and fosfomycin are antibiotics commonly used to treat methicillin-resistant Staphylococcus aureus (MRSA) infection. This study compares the in vitro inhibitory effects against MRSA of
Around 1% of total hip replacements are follow by prosthetic joint infection (PJI). There is uncertainty about best treatment method for PJI, and the most recent high quality systematic reviews in unselected patients indicates that re-infection rates following one-stage and two-stage revision arthroplasty are relatively similar. In the absence of evidence randomised controlled trials will help to identify the most clinically and cost-effective treatment for PJI. Before such trials are conducted, there is a need to establish reasons for current practice and to identify whether trials are feasible. This study aimed to deliver research that would inform trial design. Specifically, we aimed to characterise consultant orthopaedic surgeons' decisions about performing either one-stage or two-stage exchange arthroplasty for patients with PJI after hip replacement and to identify whether a randomised trial comparing one-stage with two-stage revision would be possible. Semi-structured interviews were conducted with 12 consultant surgeons from 5 high-volume National Health Service (NHS) orthopaedic departments in the UK. Surgeons were sampled on the basis that they perform revision surgery for PJI after hip arthroplasty and final sample size was justified on the basis of thematic saturation. Surgeons were interviewed face-to-face (n=2) or via telephone (n=10). The interview study took place before design of a multicentre prospective randomised controlled trial comparing patient and clinical outcomes after one-stage or two-stage revision arthroplasty. Data were audio-recorded, transcribed, anonymised and analysed using a thematic approach, with 25% of transcripts independently double-coded. Results: There is no standard surgical response to the treatment of PJI and surgeons manage a complex balance of factors when choosing a surgical strategy. These include multiple patient-related factors, their own knowledge and expertise, available infrastructure and the infecting organism. Surgeons questioned whether evidence supports the emergence of two-stage revision as a method. They described the use of loosely cemented
Infected non-unions of proximal femoral fractures are difficult to treat. If debridement and revision fixation is unsuccessful, staged revision arthroplasty may be required. Non-viable tissue must be resected, coupled with the introduction of an antibiotic-eluting temporary spacer prior to definitive reconstruction. Definitive tissue microbiological diagnosis and targeted antibiotic therapy are required. In cases of significant proximal femoral bone loss, spacing options are limited. We present a case of a bisphosphonate-induced subtrochanteric fracture that progressed to infected non-union. Despite multiple washouts and two revision fixations, the infection remained active with an unfavourable antibiogram. The patient required staged revision arthroplasty including a proximal femoral resection. To enable better function by maintaining leg length and offset, a custom-made antibiotic-eluting
