Multicenter Study
Introduction of a mobile device based tertiary survey application reduces missed injuries: A multi-center prospective study.
Missed injuries during the initial assessment are a major cause of morbidity after trauma. The tertiary survey is a head-to-toe exam designed to identify any injuries missed after initial resuscitation. We designed a novel mobile device application (Physician Assist Trauma Software [PATS]) to standardize performance and documentation of the tertiary survey. This study was undertaken to assess the feasibility of introducing PATS into routine clinical practice, as well as its capacity to reduce missed injuries. ⋯ The implementation of a mobile tertiary survey application significantly reduced missed injuries at both a higher- and medium-volume trauma center. The use of this application resulted in a significant improvement in compliance with documentation of the tertiary survey.

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.

Infection after operative fixation of tibia plateau fractures. A risk factor analysis.
Surgical fixation of tibial plateau fractures has been shown to improve long-term functional outcomes, but a major complication is that of postoperative infection which can be deleterious to long-term outcomes. This study aims to assess the impact of common comorbidities on the risk of postoperative infection. ⋯ This study has identified excessive alcohol consumption as the only independent risk factor for postoperative infection in patients with all types of tibial plateau fracture treated with operative fixation. No relationship between smoking, diabetes nor obesity was found for postoperative infection.
