Randomized Controlled Trial
A prospective randomized controlled trial of a bioresorbable calcium phosphate paste (alpha-BSM) in treatment of displaced intra-articular calcaneal fractures.
Displaced intra-articular calcaneal fractures are devastating injuries and pose a therapeutic challenge. The purpose of this study was to determine whether open reduction internal fixation (ORIF) plus an injectable bioresorbable calcium phosphate paste (alpha-BSM [bone substitute material]) is superior to ORIF alone in the treatment of calcaneal bone voids encountered after operative treatment of displaced intra-articular calcaneal fractures. ⋯ These results support the use of an injectable, in situ hardening calcium phosphate paste to fill the bone void after a displaced intra-articular calcaneal fracture. There was no impact on general health, limb specific function, and pain past 2 years and no associated complications with alpha-BSM use, supporting it safety as an augment to ORIF.

Treatment of distal femoral fractures by percutaneous plating without direct manipulation of the fracture fragments leads to good clinical outcome. Percutaneous plating has traditionally involved using a dynamic condylar screw (DCS) and the less invasive stabilization system (LISS) was reported. The biomechanical study showed that the LISS had the enhanced ability to withstand higher loads. However, there were no clinical comparison study of distal femoral fractures treated with DCS and LISS. The aim of this study was to outline any differences in clinical and radiological results between the DCS and the LISS for treating distal femoral fractures. ⋯ Minimally invasive percutaneous plating with the DCS or the LISS provides good outcome with few complications in the treatment of distal femoral fractures. Both systems minimize soft tissue trauma. LISS seems to have lower risk of early implant loosening than the DCS.

As outcome to severe trauma is frequently affected by massive blood loss and consecutive hemorrhagic shock, replacement of red blood cell (RBC) units remains indispensable. Administration of RBC units is an independent risk factor for adverse outcome in patients with trauma. The impact of massive blood transfusion or uncrossmatched blood transfusion on the patients' immune response in the early posttraumatic period remains unclear. ⋯ We exhibited for the first time a serial, sequential screening analysis of monocyte messenger RNA expression patterns in patients with multiple trauma indicating a strongly significant association between the patients' genomic response in blood monocytes and massive or uncrossmatched RBC substitution.

Many trauma centers use the pan-computed tomography (CT) scan (head, neck, chest, and abdomen/pelvis) for the evaluation of blunt trauma. This prospective observational study was undertaken to determine whether a more selective approach could be justified. ⋯ In this small sample, physicians were willing to omit 27% of scans. If this was done, two injuries requiring immediate actions would have been missed initially, and other potentially important injuries would have been missed in 17% of patients.

Hurricane Katrina, which struck the Gulf Coast of the United States in August 2005, initially displaced over a million people from their primary place of residence. Displaced older adults subsequently faced challenges, such as new or inferior living conditions, which could increase vulnerability to serious or life-threatening injuries such as hip fracture. The aim of this study was to determine whether Katrina victims who were displaced for a prolonged period of time were more likely to experience injuries than nondisplaced victims. ⋯ Prolonged displacement is associated with increased risk of fracture in older adults. Emergency planners should screen temporary housing for injury hazards, and clinicians should regard displaced older adults as a vulnerable population in need of interventions such as risk communication messaging.
