The SOLARIO trial is a randomised controlled non-inferiority trial of antibiotic strategy for bone and joint infection. SOLARIO compares short or long post-operative systemic antibiotic duration, for patients with confirmed infections, who had local antibiotics implanted and no infected metalwork retained when undergoing surgery. This analysis compared systemic antibiotic use in the short (intervention) and long (standard of care) arms of the trial, in the 12 months after index surgery. Data was collected prospectively from study randomisation, within 7 days of index surgery. All systemic antibiotics prescribed for the index infection were recorded, from health records and patient recall, at randomisation, 6 weeks, 3-6 months and 12 months after study entry. Start and end dates for each antibiotic were recorded.Aim

People awaiting surgery for bone and joint infection may be recommended to stop smoking to improve anaesthetic and surgical outcomes. However, restricting curative surgical treatment to non-smokers on the basis of potentially worse surgical outcomes is not validated for functional outcomes or quality of life differences between patients who do and do not smoke. This study used secondary analysis of trial data to ask: do peri-operative non-smokers have a greater improvement in their quality of life 12 months after surgery for bone and joint infection, compared with non-smokers? Participants in the SOLARIO and OVIVA clinical trials who had complete baseline and 12 month EQ-5D-5L or EQ-5D-3L scores were included. Smoking status was ascertained at baseline study enrolment from participant self-report. Normalised quality of life scores were calculated for participants at baseline and 12 months, based on contemporaneous health state scores for England. Baseline and 12 month scores were compared to calculate a post-operative increment in quality of life.Aim

The FitBone lengthening nail (Orthofix UK) is an intramedullary device licensed for the lengthening of long bones in adults in the UK. It contains a motor powered by electricity transmitted via an induction coil placed underneath the skin. It was developed in Germany two decades ago but uptake in the UK has only started more recently. The aim of this study was to review the first cohort of FitBone lengthening nails in a unit with significant experience of other lengthening nails (including PRECICE and Stryde). Demographic, clinical and radiological data was prospectively collected on all FitBone cases starting in February 2022. Accuracy of lengthening rate, patient satisfaction and implant issues were all considered. Complications and learning points were recorded and discussed by the multidisciplinary team involved in the patients care.Introduction

A greater emphasis has been placed on fracture related infection (FRI) orthopaedic practice as a separate entity in recent years. Since the publication of the FRI consensus definition and guidelines, there has been an increase in the published literature on the topic and a move towards considering FRI as separate from general orthopaedic practice and as work that requires a more specialist approach. The aim of this study was to audit current FRI practice in the UK. Orthopaedic practice related to FRI in the UK was audited using a semi-structured questionnaire. Respondents were from a range of institutions, specialties and clinical roles to reflect the multi-disciplinary nature of treating FRI. The online tool SurveyMonkey was used to share the survey at the 2022 annual meeting of the British Limb Reconstruction Society. Twenty-one questions were asked in the following domains: scope of practice, theatre and clinic capacity, availability of the multidisciplinary team, renumeration for work and scope of FRI networks.Introduction

The Exeter™ V40 cemented polished tapered stem system has demonstrated excellent long-term outcomes. This paper presents a systematic review of the existing literature and reports on a large case series comparing implant fractures between the Exeter V40 series; 125 mm and conventional length stem systems. A systematic literature search was performed adhering to PRISMA criteria. In parallel we performed a retrospective single centre study of Exeter™ V40 femoral stem prosthetic fractures between April 2003– June 2020. There are 25 reported cases of such prosthetic fractures confined to small case series and case reports within the literature. We report an additional 19 cases to the literature (mean age 66.3 ± 11.7 years; 12 female [63%]; body mass index 32.9 ± 5.9 kg/m2). The mean time from index procedure to fracture was 7.8 years (2.5–16.3, ±3.6). Exeter V40 stem fracture incidence was 0.27%. Incidence was significantly higher in 125 mm length stems compared to ≥150 mm length stems (1.26% vs 0.13%, respectively, p <0.001) and revision arthroplasty (1.209% vs 0.149%, p <0.001). When comparing different stem length cohorts, 125-mm short-stem were associated with stem body fractures (92% vs 29%, p = 0.0095), earlier time to fracture (6.2 vs 11.0 years, p = 0.0018), younger patient age at time of fracture (62.7 vs 72.6 years old, p = 0.037) and female sex (75% vs 43%, p = 0.33). This case series in conjunction with the systematic review provides evidence stem morphology plays a role in femoral implant fracture. This complication remains rare, although we report a significantly higher incidence at up to 17 years follow-up than in the literature. As femoral geometries remain the same, increasing BMIs in THR patients should raise concern. Short 125 mm length Exeter V40 stems undoubtedly have a role in restoring anatomy and biomechanics in smaller femoral geometries, although the surgeon has to appreciate the higher risk of stem fracture and the associated predisposing factors which may necessitate meticulous surgical technique and planning.
