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...

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...

Background: Conventional fixation methods of posterior wall acetabular fractures feature the use of plating and lagscrews. However, fixation of posterior wall fractures with buttress plating alone offers potential advantages by avoidingthe hardware complications related to hardware placement through the wall fragment. The purpose of this study wasto examine if buttress plating...

conclusion for the identification of nasal bone fractures, ct was significantly superior to conventional radiography. although a staff radiologist showed better values in the identification of nasal bone fracture and differentiation between depressed and non-depressed fractures than a trainee, there was no statistically significant difference in the interpretation of conventional radiography an...

purpose: surgeons performing an ilioinguinal exposure for acetabular fracture surgery need to be aware of aberrant findings such as inguinal hernias and spermatic cord lesions. the purpose of this study is to report these occurrences in a clinical series of adult males undergoing acetabular fracture fixation and a series of adult male cadavers. the secondary aim is to characterize these abnorma...

in this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. for this purpose the 3-d unsteady euler equations in cylindrical coordinate are averaged in tangential direction. therefore, the equations are reduced to a 2-d system. by averaging the tangential component of momentum equation, a blade force will result. axial and r...

  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) wi...

osteoporosis is the most common metabolic bone disease. in addition to morbidity, osteoporotic fractures also increase mortality risk in affected patients. enough evidence is not available to indicate that, like western countries, osteoporosis is a public health problem in iran. therefore emrc planned to estimate the burden of osteoporotic fractures in year 2001 based on existing sources of dat...

background:  little is known about trends and predictors of hardware related infection following open reduction and internal fixation (orif) of extremity fractures, one of the major causes of failure following orif. the present study was designed and conducted to determine trends and predictors of infection-related hardware removal following orif of extremities using a nationally representative...
