Background: The gold-standard treatment for Vancouver type B2 and B3 fractures is revision arthroplasty. This procedure can be prolonged and complex, posing challenges for patients with severe medical comorbidities and reduced physical status. Recently, osteosynthesis has been proposed as an alternative treatment for B2 periprosthetic femoral fractures (PFF) in frail patients, though its efficacy compared to revision arthroplasty has not been studied in detail.

Methods: A retrospective study was conducted from 2012 to 2022, comparing complications, mortality, length of stay, gait ability, hemoglobin decrease, and blood transfusion rates between 44 patients undergoing treatment for B2 or B3 PPF with either stem-revision arthroplasty (n = 28) or open reduction and internal fixation (ORIF) with plates and screws (n = 16).

Results: The results showed no significant differences in mortality, complications, hemoglobin decrease, blood transfusion rate, or length of stay between the two groups. In the stem-revision group, 11 patients (60.7 %) experienced a medical complication, while 7 patients (43.8 %) in the ORIF group had complications (p = 0.778). The mortality rate within the first year post-surgery was 17.9 % (5 patients) in the stem-revision group compared to 18.8 % (3 patients) in the ORIF group (p = 0.943). Surgical complications occurred in 2 patients (7.1 %) in the stem-revision group and in 4 patients (25 %) in the ORIF group (p = 0.101). Blood transfusions were required in 17 patients (60.7 %) in the stem-revision group and in 8 patients (50 %) in the ORIF group (p = 0.829).

Conclusions: This study suggests that ORIF is an acceptable treatment option for patients with B2 or B3 PFF, especially for those with severe medical comorbidities and reduced physical status who may not tolerate revision arthroplasty. However, further research with larger sample sizes and longer follow-up periods is needed to confirm these findings.

Level of evidence: IV.

Background: Canadian Armed Forces (CAF) operate in environments that challenge patient care, especially trauma. Military personnel often find themselves in remote settings without conventional healthcare facilities. Treating traumatic injuries, particularly hemorrhagic shock, often necessitates prehospital blood transfusion. This study aims to present an overview of the current CAF prehospital transfusion practices. Furthermore, the study compared current and developing protocols against expert-recommended guidelines.

Methods: A cross-sectional survey design was employed to describe and compare CAF prehospital blood transfusion practices and protocols against expert recommendations. Topics included protocols, equipment, and procedures. An online survey targeted medical leadership and providers within CAF, with data collected from August 15 to December 15, 2023. Results were summarized descriptively. This study received approval from the Unity Health Toronto Research Ethics Board (REB 23-087).

Results: Units and teams with prehospital blood transfusion capabilities were contacted, achieving a 100 % response rate. Within CAF, Canadian Special Operations Forces Command (CANSOFCOM), Mobile Surgical Resuscitation Team (MSRT), and Canadian Medical Emergency Response Team (CMERT) possess these capabilities, established between 2013 and 2018. These programs are crucial for military operations. CAF has access to standard blood components, cold Leuko-Reduced Whole Blood (LrWB), and factor concentrates from Canadian Blood Services (CBS), available for both domestic and international missions given adequate planning and favorable conditions. Key findings indicate high adherence to recommended practices, some variability in the transfusion process, and potential benefits of standardizing prehospital transfusion practices.

Conclusions: This study provided insights into CAF's implementation of prehospital transfusion practices, highlighting high adherence to national expert recommendations and the importance of structured protocols in military prehospital trauma management.

Implications of key findings: CAF's approach and adoption of prehospital transfusion protocols lay a strong foundation for managing trauma patients in remote settings and for expanding prehospital transfusion capabilities across CFHS deployed assets. Further research is needed to advance military trauma care by adapting prehospital blood transfusion to dynamic tactical landscapes and evolving technologies.

Purpose: We described clinical outcomes for patients with blunt splenic injuries treated with transarterial embolization (TAE) based on their hemodynamic status.

Materials and methods: This is a retrospective two-center study of adult patients with splenic injuries who underwent emergency TAE between January 2011 and December 2022. Patients were divided into two groups; hemodynamically unstable (HDU) and hemodynamically stable (HDS) patients. HDU patients were defined as transient- or non-responders to fluid resuscitation and HDS as responders. When immediate laparotomy was not possible for HDU patients, angiography and embolization were performed. The primary outcome was the survival discharge rate. Rebleeding and splenectomy rate was also investigated.

Results: Of 38 patients underwent emergency TAE for splenic trauma, 17 were HDU patients and 21 were HDS patients. The survival discharge rate was 88.2 % (15/17) in the HDU- and 100 % in HDS patients (p = 0.193). Rebleeding rate was 23.5 % (4/17) in HDU- and 5.0 % (1/21) in HDS patients (p = 0.15). Splenectomy was required for one HDU patient (5.9 %) for rebleeding.

Conclusion: The survival discharge rate of TAE for splenic trauma in HDU patients was acceptable with a low rate of splenectomy. Further comparative studies of TAE versus operative management in HDU patients are needed to prove the usefulness of TAE.

Objective: The primary objective of this study is to assess common sites of injury and the associated imaging findings in penetrating injuries. We pay particular attention to gluteal, anterior abdominal wall and junctional zone injuries. The aim is to highlight areas of diagnostic uncertainty and discrepancy between imaging and surgical findings, to improve review areas in trauma reporting.

Methods: A retrospective, observational study reviewing all paediatric admissions to the emergency department of a major trauma Centre with a penetrating injury, from 2015 to 2019.

Results: Gluteal penetrating injuries are by far the most commonly sustained injury in the adolescent population, making up over 1/3 of cases. The vast majority of these cases sustained superficial injuries or shallow intramuscular haematomas, however in a small group (15%), serious vascular or rectal injuries were demonstrated on dual phase CT, requiring emergent surgical or endovascular treatment. Penetrating injuries to the anterior abdominal wall and junctional zone are less common but are associated with higher morbidity, with 43% of cases demonstrating solid organ or bowel injury. These cases also lead to an increased degree of diagnostic uncertainty.

Conclusion: Gluteal injuries are common and although the overall morbidity of these cases is low, these patients are at risk of serious and life threatening consequences such as vascular and rectal injury and it is imperative that these complications are considered and ruled out via dual phase CT or direct visualization. Anterior abdominal wall and junctional zone injuries are less common, but lead to greater morbidity and also greater diagnostic uncertainty. The use of other salient findings as described in this report can aid diagnostic accuracy and reduce discrepancies.
