We aimed to determine whether the outcome of severely injured patients differs based on admission time (office hours vs. non-office hours) at a tertiary trauma centre without an in-house trauma surgeon consultant available at all times. We also studied subgroups of patients presenting with a New Injury Severity Score (NISS) ≥ 25 and patients experiencing major bleeding. ⋯ We found that arrival time did not affect mortality among patients with severe blunt trauma treated at a tertiary trauma centre without an in-house trauma surgeon consultant available at all times. Thus, this type of unit can maintain a standard of care during non-office hours by investing in precise treatment protocols and continuous education. However, our results do not apply to penetrating trauma injury patients.

The incidence of invasive treatment of rib fracture has increased significantly over the last decade however the evidence of improved patient outcomes to support this is lacking. A systematic review was performed to identify patient reported outcome measures (PROMs) used in the assessment of outcomes following chest wall injury. The quality of evidence for the psychometric properties of the identified PROMs was graded using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. ⋯ The lack of validated outcome measures for rib fracture patients is a significant limitation of the current literature. Further studies are needed to provide validated outcome measures to ensure accuracy of the reported results and conclusions. As interventions for rib fractures have become more common in both research and clinical practice this has become an urgent priority.

Multicenter Study
Potential bone fragility of mid-shaft atypical femoral fracture: Biomechanical analysis by a CT-based nonlinear finite element method.
The authors previously reported a CT-based nonlinear finite element analysis (nonlinear CT/FEA) model to investigate loading stress distribution in the femoral shaft of patients with atypical femoral fractures (AFFs). This showed that stress distribution, influenced primarily by femoral bowing, may determine the location of AFF. Here, we demonstrate the locational characteristics associated with AFFs in an Asian, specifically Japanese, population regarding bone strength. This is the second report from our multicentre research project suggesting a possible new concept of diagnostic criteria or treatment according to AFF subtype. ⋯ AFF has different features, in terms of bone strength, depending on fracture location. At the very least, Japanese patients with mid-shaft AFF could be at high risk of hip fracture because of bone fragility, in contrast to the firm bone of subtrochanteric AFF. For internal fixation of mid-shaft AFF using an IM nail, cervical screw insertion toward the femoral head might be recommended to prevent possible hip fracture.

Intramedullary nailing is already established technique for the treatment of two and three-part fractures of proximal humerus. The aim of the study was to prospectively evaluate the efficacy and functional outcome after treatment of four-part fractures of proximal humerus with Multiloc proximal humeral nail. ⋯ Level 2b - monocentric prospective cohort study.
