OBJECTIVE This report presents bone measurement data from dual-energy X-ray absorptiometry scans of the lumbar spine and proximal femur for persons aged 8 years and over from the National Health and Nutrition Examination Survey (NHANES) 2005-2008. METHODS Means, standard deviations, and selected percentiles were calculated for the proximal femur and lumbar spine (total and subregions) by sex,...

One of the most important but least studied environmental factors playing a major role in bone physiology is gravity. While the knowledge of deleterious effects of microgravity on the skeleton is expanding, little is known about hypergravity and its osteogenic potential. Centrifugation was used to assess effects of 21-day continuous 2- or 3-g acceleration on femur and L2-vertebra of 7-wk-old ma...

Retrograde interlocking nail was used as the method of fixation in 35 different cases of combination of complex femoral fractures. We performed this procedure in fractures of femoral shaft associated with fracture neck femur, pathological fractures of proximal third of femur with trochanteric pathology, ipsilateral fracture of femur and tibia in polytrauma cases with multiple other injuries, in...

SUMMARY Determination of gestational age have several usages in obstetrics and gynecology. The relation between fetal femur length and gestational age has determined in this research using real time sonography. 1000 iranian pregnant women between 12-40 weeks of gestation with accuratic last menstrual period and with out the history of diabetes lllellitus, hypertension, renal disease and fetal ...

BACKGROUND Clinical factors that affect the likelihood of abuse in children with femur fractures have not been well elucidated. Consequently, specifying which children with femur fractures warrant an abuse evaluation is difficult. Therefore the purpose of this study is to estimate the proportion of femur fractures in young children attributable to abuse and to identify demographic, injury and p...

BACKGROUND Tumors of the distal femur and diaphysis with proximal metaphyseal extension into the femur present a challenge for limb salvage. The conventional treatment consists of limb salvage with total femur replacement. This case study aims to present preliminary results and experience with short-stem reconstruction, focusing on the mechanical stability of the procedure. METHODS Sixteen sh...

BACKGROUND Fractures of the tibia and femur are common after automobile versus pedestrian (AVP) injuries. This study evaluates the effect of age on the type of fracture and the incidence and type of associated injuries. METHODS All patients involved in an AVP crash from January 1, 1995, through June 30, 2006, were included in the study. Variables obtained from our trauma registry included age...

The authors performed a cadaveric study to evaluate the efficacy of multiple fluoroscopic projections in detecting intra-articular penetration of the screws during femoral neck fracture fixation and also to determine the most suitable radiographic projection. Models of intra-articular penetration in 8 normal proximal femur specimens were created by placing the pins in different quadrants of the...

simultaneous fractures of the femoral neck and shaft are not common injuries, though they cannot be considered rare. herein, we report our experience with a patient with bilateral occurance of this injury. up to the best of our knowkedge this is the first case reported in literature in which correct diagnosis was made initially. both femurs were fixed using broad 4.5 mm dynamic compression plat...

background: fractures of the femoral shaft are mostly the result of high-energy accidents that also cause multiple trauma injuries, in particular ipsilateral knee and hip injuries. the purpose of this study was to investigate the incidence of injuries associated with femoral shaft fractures and how many of them were undetected. methods: we studied 148 patients (150 femoral shaft fractures) with...
