To explore the utility of legacy demographic factors and ballistic injury mechanism relative to popular markers of socioeconomic status as prognostic indicators of 10-year mortality following hospital discharge in a young, healthy patient population with isolated orthopedic trauma injuries. ⋯ Low SES is associated with a greater hazard of long-term mortality than ballistic injury mechanism, race, gender, and medically diagnosable behavioral risk factors in a young, healthy orthopedic trauma population with isolated extremity injury.

3D-navigation for percutaneous sacroiliac (SI) screw fixation is becoming increasingly common and several studies report great advantages of this technology. However, there is still limited clinical evidence on the efficacy regarding radiation exposure for patient and personnel. ⋯ Our data clearly suggests that the use of 3D-navigation for percutaneous SI screw fixation decreases radiation exposure for medical personnel, while increasing radiation exposure for patients. Furthermore, intraoperative precision is improved, even in more challenging operations.

The aim of this study is to investigate stiffness and the maximum load to failure values of single- and double-screw fixation of oblique medial malleolus fractures using partially threaded cancellous screws. Our hypothesis is that single-screw fixation of medial malleolus fractures after SER injuries provides similar stiffness when compared with double-screw fixation. ⋯ Fixation with one 4.0 mm partially threaded cancellous screw was not shown to be biomechanically inferior to fixation with two 4.0 mm partially threaded cancellous screws in an oblique fracture of the medial malleolus, supporting previous clinical studies that have shown that one screw is sufficient for fractures of the medial malleolus.

Project Safe Neighborhoods: Dallas (PSND) is part of a national initiative that partners federal, state, and local stakeholders and law enforcement to reduce violent crime, especially firearm violence, in select communities. The authors' hospital is located centrally in PSND's target areas, and the trauma center's service area fully covers the target areas. This cohort study evaluated PSND's effectiveness by examining if PSND's April 2018 launch was associated with decreases in (1) violent crime or (2) the rate of patients presenting with firearm and assaultive injuries. ⋯ Results suggest PSND was ineffective. Criminal activity in the target area was not reduced relative to its pre-intervention levels or relative to the non-target areas. Offenders may have moved outside the target areas to evade increased scrutiny. Additionally, rates of firearm and assaultive injuries increased. As trusted third parties, trauma centers should consider evaluating local crime and injury prevention programs for effectiveness.

Hip fracture patients are recommended to undergo surgery within 24-36 h. The present study aimed to analyze the current status of hip fracture surgery among the elderly in China. ⋯ The major issues in diagnosing and treating elderly patients with hip fractures in China are the long waiting time for surgery and the low surgery rate.
