Multicenter Study
Predicting tibia shaft nonunions at initial fixation: An external validation of the Nonunion Risk Determination (NURD) score in the SPRINT trial data.
Predictive models are common in orthopedic research; however, most models are not validated in an external population. The Nonunion Risk Determination (NURD) score was developed using a single-center cohort of 382 patients to reliably predict tibia shaft nonunions at the time of initial intramedullary nail fixation. The purpose of this study was to externally validate the NURD score using data from the SPRINT Trial. ⋯ Based on our external validation, the NURD score lacks generalizability as it underperforms with respect to discrimination in the SPRINT trial data. However, after adjusting for case-mix differences, the performance of the NURD score is comparable between the two datasets, suggesting robust reproducibility.

Multicenter Study
The effect of anticoagulation on outcomes after liver and spleen injuries: A research consortium of New England centers for trauma (ReCONECT) study.
Liver and spleen injuries are the most commonly injured solid organs, the effects of anticoagulation on these injuries has not yet been well characterized. ⋯ The use of anticoagulation did not result in a difference in outcomes among patients with spleen and/or liver injuries.

Complication Rates after Lateral Plate Fixation of Periprosthetic Distal Femur Fractures: A Multicenter Study.
Periprosthetic fractures of the distal femur can be challenging injuries to treat; nonunion rates of up to 22% have been reported. The purpose of this study was to determine the rate of complications and nonunion in a multicenter series, and to identify patient or surgical factors that were associated with nonunion. ⋯ In this series of 55 patients with periprosthetic distal femur fractures treated with precontoured lateral locking plates, 18% developed nonunion and the overall complication rate was 24%. No patient or surgical variables were identified as risk factors. Future research should seek to identify patients at high risk for complication and nonunion who could benefit from alternative fixation strategies or distal femoral replacement.

Review Multicenter Study
Epidemiologic characteristics of traumatic fractures during the outbreak of coronavirus disease 2019 (COVID-19) in China: A retrospective & comparative multi-center study.
Amid the outbreak of coronavirus disease 2019 (COVID-19), effective measures have been taken in China to suggest people wearing masks and staying at home. The majority of the people stayed at home, which had an obvious impact on the occurrence of traumatic fractures. This study aimed to describe the epidemiologic characteristics of traumatic fractures during the COVID-19, and provide reference for targeted control measures for the whole world by proposing China's experiences. ⋯ Our findings confirmed the importance of the measures to restrict people's movement and wear masks in the prevention of the spread of COVID-19. The epidemiological characteristics of traumatic fractures amid the epidemic changes dramatically, and more attempts should be focused on the prevention of low energy injuries of elderly population.

Multicenter Study Observational Study
Accuracy of early warning scores for predicting serious adverse events in pre-hospital traumatic injury.
Traumatically injured patients are at higher risk of serious adverse events. Numerous physiological scoring systems are employed as diagnostic and/or prognostic tools. The objective of this study was to evaluate the scales most commonly used by emergency medical services for the early detection of prehospital serious adverse events. ⋯ All scoring systems were able to detect prehospital serious adverse events early in traumatic injury; therefore, any of the scoring systems could be useful and represent an ideal tool for routine use by emergency medical services in cases of traumatic injury.
