Femoral shaft fractures are among the most severe injuries of the skeleton. They are associated with high morbidity and mortality. The most appropriate treatment depending on the type of fracture and location level should be chosen. A finite element model of the femur has been developed, analyzing various types of fractures in the subtrochanteric and diaphyseal supracondylar area, with several gap sizes, being stabilized with a single combination of screws for the intramedullary nail. The mechanical strength of the nail against bending and compression efforts was studied comparing two materials for the nail: stainless steel and titanium alloy...

BACKGROUND: Blunt trauma is the most frequent mechanism of injury in multiple trauma, commonly resulting from road traffic collisions or falls. Two of the most frequent injuries in patients with multiple trauma are chest trauma and extremity fracture. Several trauma mouse models combine chest trauma and head injury, but no trauma mouse model to date includes the combination of long bone fractures and chest trauma. Outcome is essentially determined by the combination of these injuries...

BACKGROUND: Recognizing patients at risk for pulmonary complications (PC) is of high clinical relevance. Migration of polymorphonuclear leukocytes (PMN) to inflammatory sites plays an important role in PC, and is tightly regulated by specific chemokines including interleukin (IL)-8 and other mediators such as leukotriene (LT)B4. Previously, we have reported that LTB4 indicated early patients at risk for PC after trauma. Here, the relevance of LTB4 to indicating lung integrity in a newly established long-term porcine severe trauma model (polytrauma, PT) was explored...

Christine W Paine, Joanne N Wood
Skeletal surveys (SSs) have been identified as a key component of the evaluation for suspected abuse in young children, but variability in SS utilization has been reported. Thus, we aimed to describe the utilization patterns, yield, and risks of obtaining SS in young children through a systematic literature review. We searched PubMed/MEDLINE and CINAHL databases for articles published between 1990 and 2016 on SS. We calculated study-specific percentages of SS utilization and detection of occult fractures and examined the likelihoods that patient characteristics predict SS utilization and detection of occult fractures...

In their post-traumatic course, trauma patients suffering from multiple injuries have a high risk for immune dysregulation, which may contribute to post-injury complications and late mortality. Monocytes as specific effector cells of the innate immunity play a crucial role in inflammation. Using their Pattern Recognition Receptors (PRRs), notably Toll-Like Receptors (TLR), the monocytes recognize pathogens and/or pathogen-associated molecular patterns (PAMPs) and organize their clearance. TLR2 is the major receptor for particles of gram-positive bacteria, and initiates their phagocytosis...

OBJECTIVE: In a context of bone fragility, primitive and subsequent fractures are a growing problem in the industrialized countries where the mean age of the population is constantly increasing. Among the various factors that favor a fragility fracture, the most important is osteoporosis, a pathology that can be prevented through diagnostic screenings and treated by pharmacological and rehabilitative therapies. The aim of this study is to identify the subjects who are likely to have a higher risk of subsequent fractures of the trochanteric region through a retrospective radiographic evaluation of patients affected by low-energy trochanteric fractures and operated by intramedullary fixation between June 2013 and June 2015, so they can be targeted for prevention interventions...

Osteophytes are a typical radiographic finding during osteoarthritis (OA), but the mechanisms leading to their formation are not well known. Comparatively, fracture calluses have been studied extensively; therefore, drawing comparisons between osteophytes and fracture calluses may lead to a deeper understanding of osteophyte formation. In this study, we compared the time courses of osteophyte and fracture callus formation, and investigated mechanisms contributing to development of these structure. Additionally, we investigated the effect of mechanical unloading on the formation of both fracture calluses and osteophytes...

Skeletal tibial traction is a temporizing measure used preoperatively for femoral fractures to improve the length and alignment of the limb and provide pain relief. The goal of this study was to identify possible neurovascular morbidity associated with the use of bedside skeletal tibial traction to treat femur fractures. All femoral fractures treated with proximal tibial traction during a 10-year period at an urban level I trauma center were retrospectively reviewed. The medical record was reviewed to determine whether a pin-related complication had occurred...

Intertrochanteric femur fractures are common injuries associated with significant patient morbidity and mortality and high societal costs. Although intramedullary devices have shown promise for treating a wide range of intertrochanteric femur fractures, improper technique can lead to malalignment, fracture displacement and/or iatrogenic fractures. In particular, a "wedge effect" has been described, in which the passage of conical reamers and the intramedullary nail itself results in distraction of intertrochanteric fragments with lateralization of the shaft from the femoral neck and varus malalignment...

INTRODUCTION: Impalement injury is a rare type of mechanical injury following forceful insertion of projecting object into the body. Careful planning for removal of the impaling object is essential to decrease the blood loss and preserve the function of the injured organ. PRESENTATION OF CASE: A 27 year-old male fell from 4m height over a U shaped projecting up metallic bar. The bar penetrated the left side of the pelvis and traversed through the left iliac bone causing a comminuted fracture in the supra-acetabular region extending to the left psoas muscle, injuring the viscera and causing fracture of the right femur...
