BackgroundThe proximal femoral nail is a commonly used fixation device for extra-capsular neck of femur fractures at our UK NHS Trust. Fracture-related infection (FRI) is a catastrophic complication that can be associated with internal fixation. FRI is often diagnosed late, and causes significant impact on the patient and healthcare system, leading to extended hospital stays, reduced quality of life, high healthcare costs and increased mortality and morbidity.AimThis study aims to evaluate whether failed proximal femoral nails treated at a major trauma centre in the United Kingdom are undergoing routine intraoperative microbiology sampling, as outlined by the FRI Consensus Group in 2020, and also to establish how often fracture-related infection is present in failed proximal femoral nails.MethodElectronic patient record systems were reviewed over a 4-year period between 2018-2022 to identify patients who had a proximal femoral nailing, and those who required revision surgery. From this cohort, we then identified whether sampling had taken place during revision surgery, and the number of samples taken.Results1041 proximal femoral nails were performed at our trust during the 4-year period. 60 of these implants failed, with 52 of these undergoing revision surgery at our hospital.  Only 56% cases had intra-operative samples taken for microbiology testing, with an average of 9 samples sent per case. Intra-operative sampling confirmed infection in 25% of cases with samples sent.  Of the cases requiring ≥ 3 operations, 75% of cases had confirmed infection.DiscussionThe data shows that more can be done to ensure earlier diagnosis of fracture-related infection in failed proximal femoral nails. We should have a high suspicion of FRI in this cohort of patients. This study highlights the importance of a standardised protocol to ensure routine intra-operative sampling during proximal femoral nail revision surgery.Copyright © 2024 Elsevier Ltd.
