Abdominopelvic injuries are common, and bleeding occurring in both cavities requires various bleeding control techniques i.e., laparotomy, angiographic embolization (AE), and orthopedic fixation. Hence, the use of Trauma Hybrid Operating Room (THOR) in abdominopelvic injuries has theoretical advantages including rapid bleeding control and minimizing patient transportation. The objective of the present study is to evaluate the impact of THOR in abdominopelvic injuries. ⋯ THOR eliminated transit time, resulting in shorter procedure time in abdominopelvic trauma patients requiring bleeding-control intervention. Although overall mortality reduction could not be demonstrated, the mortality due to exsanguination was reduced in THOR group.

Distal femoral fractures are fractures associated with high rates of morbidity and mortality, affecting to three different groups of individuals: younger people suffering high-energy trauma, elderly people with fragile bones and people with periprosthetic fractures around previous total knee arthroplasty. They have been classically treated with conventional plates and intramedullary nails and more recently with locked plates that have increased their indications to more types of fractures. The main objective of the present work is the biomechanical study, by means of finite element simulation, of the stability achieved in the osteosynthesis of femoral fractures in zones 4 and 5 of Wiss, by using locked plates with different plate lengths and different screw configurations, and analysing the effect of screw proximity to the fracture site. ⋯ The obtained results show that more stable osteosyntheses were obtained by using shorter plates. In the cases of longer plates, it results more convenient disposing screws in a way that the upper ones are closer to fracture site. The obtained results can support surgeons to understand the biomechanics of fracture stability, and then to guide them towards the more appropriate osteosynthesis depending on the fracture type and location.
