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: humerus fractures include 5% to 8% of total fractures. non-:union: and delayed :union: of gt (gt) fractures is uncommon; however they present a challenge to the orthopedic surgeons. significant controversy surrounds optimal treatment of neglected fractures. the purpose of this article was to perform a comparative study to evaluate the outcomes of open reduction and internal fixation...

Conventional shale gas productivity prediction techniques consider fracture conductivity to be a fixed value, but in actual production processes, changes with time. Therefore, this paper proposed capacity method that considers time-dependent and validates its accuracy using commercial simulators. First, relevant parameters were obtained by fitting the improved long-term test, then seepage model...

Tibial shaft fractures are treated surgically by different methods. In the last few years interlocking intramedullary nailing has emerged as a gold standard for tibia fracture. The clinical and radiological outcome is better complications like compartment syndrome, neurovascular injuries, infection, non-union relatively less of tibia. use ILIM nail also shows reduce risk reoperation. Nail consi...

The “biological restoration” is an excellent technique for reconstruction in young traumatized teeth, which is used as intra-root reinforcement an extracted natural tooth. This article reports a case where an 11-year-old patient had his upper incisors affected by fractures from trauma. Due to the young age of the patient, the absence of the natural tooth fragment, the major structural loss and ...

In a low permeability formation, connectivity of natural and induced fractures determines overall hydraulic diffusivity in fluid flow through this formation defines effective rock permeability. Efficient evaluation fracture is nontrivial task. Here, we utilize topological concept global efficiency to evaluate connectivity. We address the impact key geometrical properties stochastic networks (fr...

Introdouction: The incidence and etiology of maxillofacial fractures are influenced by social, cultural, and environmental factors. Understanding the cause, severity, and temporal distribution of maxillofacial trauma provides an insight into the behavioral patterns of people from different countries and can also assist in establishing clinical and research priorities for effective treatment and...

Background: Femoral shaft fractures are an incapacitating pediatric injury accounting for 1.6% of all pediatric bonyinjuries. Management of these fractures is largely directed by age, fracture pattern, associated injuries, built of the childand socioeconomic status of the family. We retrospectively evaluated the use of elastic stable intramedullary nail (ESIN)in surgical management of femoral s...
