The Thompson hemiarthroplasty is a common treatment option for acute neck of femur fractures in the elderly population. Our department noted a significant number of patients returning with thigh pain, radiographic loosening and femoral osteolysis following cemented implantation of the titanium alloy version of the Thompson hemiarthroplasty. We are not aware of any previous reports documenting complications specific to the titanium Thompson implant and a retrospective cohort study was therefore initiated following clinical governance approval. 366 titanium alloy Thompson prostheses were implanted for hip fracture treatment between 2017 and 2020. As of February 2023, 6 of these have been revised at our hospital. 5 were revised for symptomatic femoral osteolysis and 1 presented with an acute periprosthetic fracture. All revised cases were determined to be aseptic. 32 living patients were excluded from recall on compassionate grounds due to permanent nursing home residence. 47 living patients were identified of which 33 attended for xray. 28 deceased and/or nursing home resident patients who had pelvis x-rays in the previous 12 months were also included in the analysis. Including the 6 index hips already revised, a total of 61 hip xrays were analysed, of which 19 hips (31.1%) showed radiographic evidence of femoral osteolysis or loosening. We conclude that there is a concerning incidence of femoral osteolysis and implant loosening associated with the titanium Thompson implant. We have discontinued use of the implant and reported our experience to the MHRA. We encourage other Scottish Health-Boards who use this implant to consider enhanced follow-up

Introduction. Surgical site infections (SSI) are related to a surgical procedure and affect the surgical wound or deeper tissues. With continuing emphasis on clinical governance and quality control, there is increasing demand from both patients and government for methods of assessing surgical results. Rates of morbidity and mortality may play important roles in these assessments. When crude comparisons between hospitals in the incidence of SSI are made, these should at least be stratified by the type of procedure. The aim of this study is to fix SSI incidence in relation to surgical procedure. Methods. This report contains data of 19.948 procedures collected from 1996 to 2008 at a Specialist Orthopaedic Hospital and analyzed by a specific software designed for the study of infection in orthopaedic and trauma surgery. The SSI surveillance is focused on categories of surgical procedure (Hip Arthroplasty, Knee Arthroplasty, Spine Surgery and Hip Fracture Surgery) with each category containing a defined set of similar procedures. A basic of demographic data and details about operation itself are collected for each procedure. Patients are followed up throughout their hospital stay and after hospital discharge. We present the incidence of SSI by risk group and surgical procedure. SSI are categorized in type, moment of diagnosis and micro-organisms reported. Analysis of the data was performed (SPSSv15.0 ®). Statistical methods used to determine significance were the independent samples t test, Pearson X2 test, Odds ratio and Spearman correlation coefficient, with a significance level of p<0,05. Results. Rates of SSI are highest in hip hemiarthroplasty after fracture and in hip and knee revision procedures. Rates of SSI increase with the number of risk factors present in the patient, especially after fracture procedures. The most common infecting micro-organism was coagulase-negative staphylococcus, followed by Staphylococcus aureus, enterococci and streptococci. 38% of the infections arise after one year of surveillance. Conclusions. Our results confirm difference in rates of SSI depending of surgical procedure in orthopaedic and trauma surgery. We believe that our decision to monitor infection with a long term follow up it's the better way to avoid under-reporting of infection. Our study has also demonstrated the extent to which the emerging problem of infection due to MRSA has affected orthopaedic surgery. The risk of acquiring SSI caused by MRSA was particularly high in patients after hip fracture surgery. Rates of SSI increase with the number of risk factors present in the patient, especially after fracture procedures. Globally, the most common infecting micro-organism was coagulase-negative staphylococcus, followed by Staphylococcus aureus, enterococci and streptococci. 38% of the infections arise after one year of surveillance

Aims

We assessed the value of the Clinical Frailty Scale (CFS) in the prediction of adverse outcome after hip fracture.

We describe the impact of a targeted performance improvement programme and the associated performance improvement interventions, on mortality rates, error rates and process of care for haemodynamically unstable patients with pelvic fractures. Clinical care and performance improvement data for 185 adult patients with exsanguinating pelvic trauma presenting to a United Kingdom Major Trauma Centre between January 2007 and January 2011 were analysed with univariate and multivariate regression and compared with National data. In total 62 patients (34%) died from their injuries and opportunities for improved care were identified in one third of deaths.

Three major interventions were introduced during the study period in response to the findings. These were a massive haemorrhage protocol, a decision-making algorithm and employment of specialist pelvic orthopaedic surgeons. Interventions which improved performance were associated with an annual reduction in mortality (odds ratio 0.64 (95% confidence interval (CI) 0.44 to 0.93), p = 0.02), a reduction in error rates (p = 0.024) and significant improvements in the targeted processes of care. Exsanguinating patients with pelvic trauma are complex to manage and are associated with high mortality rates; implementation of a targeted performance improvement programme achieved sustained improvements in mortality, error rates and trauma care in this group of severely injured patients.
