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...

Projection-based embedded discrete fracture model (pEDFM) is an effective numerical to handle the flow in fractured reservoirs, with high efficiency and strong generalization of models. However, this paper points out that pEDFM fails barriers most cases, identifies physical projection configuration fractures a key step pEDFM. This presents proves equivalence theorem, which explains geometric na...

Studies of the hydrate cores have shown that natural fractures can be frequently observed in reservoirs, resulting a fracture-filled hydrate. Therefore, it is highly necessary for industries to predict gas well productivity reservoirs. In this work, an embedded discrete fracture model applied characterize gas-hydrate The non-linear mass and energy conservation equations which are discretized wi...

  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: Tibial and femoral fractures, commonly seen in emergency departments, may be associated with various knee ligament injuries. The aim of this study was to determine the prevalence of such fracture-associated knee ligament problems, with especial attention to rapid diagnosis. Methods: This study was carried out in patients with femoral or tibial fractures who were operated on in Imam...

ABSTRACT Mandibular condyle fractures are relatively common. Because of longterm morbidity of temporomandibular joint dysfunction and ankylosis, correct management of these fractures are very important. The contraversy between closed and open approaches, has not yet been solved in the management of these fractures. In this article, we reviewed 302 cases of mandibular fractures since 19...

Background: Comminuted subtrochanteric fractures have been a challenge for orthopedic surgeons in terms of appropriate reduction and stable fixation. Numerous methods have been used for the fixation of comminuted subtrochanteric fractures among which some are accompanied with technical difficulties and complications of their own. Regarding the results of previous studies, we decided to evaluate...

Discrete fracture network (DFN) model simulations, where a fracture network can have a natural heterogeneity, is one of the most effective approaches in fluid flow analyses for naturally fractured and enhanced geothermal reservoirs. In the DFN model simulations, fractures are modeled by a pair of parallel smooth plates although real fractures have rough surfaces. Numerous field and laboratory o...
