A subtrochanteric femur fracture after cannulated screw fixation of a femoral neck fracture is a devastating complication. We hypothesized that an apex-distal screw orientation would tolerate higher loads to subtrochanteric fracture. Human cadaveric femora were instrumented with three cannulated screws in either an apex-distal or an apex-proximal configuration. Specimens were loaded along the m...

conclusions in middle-aged subjects with psc, we found a high rate of non-vertebral fractures and a moderately decreased bmd in lumbar spine and hip. fragility fractures had an impact on physical and mental aspects of hrqol. results in 32% of patients, bmd measured in the hip or spine was below 1.0 standard deviation. a history of fragility fractures (distal forearm and ribs) was reported in si...

When representing visual features such as color and shape in visual working memory (VWM), participants also represent the locations of those features as a spatial configuration of the locations of those features in the display. In everyday life, we encounter objects against some background, yet it is unclear whether the configural representation in memory obligatorily constitutes the entire dis...

0 Abstract “Space syntax” has shown that spatial configuration can be described as a set of lines covering all the areas of a layout and all the ways of moving around the one dimensional and two dimensional boundaries that it comprises. This article proposes alternative formal definitions of linear representations of spatial configuration and ways in which they can be generated. The significanc...

Abstract Background Preoperative posterior tilt is a risk factor for fixation failure in femoral neck fractures. This study aimed to evaluate the configuration of anterior positioning screw proximal plating treatment retroverted fractures terms resisting tilt. Methods We retrospectively analyzed patients with who were fixed by from January 2014 August 2019. All divided into two groups according...

introduction: this study was conducted to determine the pattern of maxillofacial fractures in three age groups of adults, adolescents, and children, using ct scan images. methods: in this cross-sectional study, ct scan images of 230 patients with maxillofacial trauma during one year were examined in terms of the number and site of fractures. the patients were divided into three age groups, chil...

Rats gathered pellets from the tops of 15.5-cm-tall poles. In a matrix of poles, bait was located on the tops of poles arranged in either a square (Experiment 1) or linear (Experiment 2) configuration. The specific locations of baited poles varied unpredictably from trial to trial. The data show that the rats' choices were controlled by the spatial configuration of baited locations. This indica...
