abstract we report a 71 year-old patient with intertrochanteric fracture who had been managed with dhs and her healed fracture complicated by a subcapital femoral neck fracture. a subcapital femoral neck fracture complicating a healed intertrochanteric fracture is rare but catastrophic event. such cases are managed in a hetereogenous manner, i.e. there exists a mixture of cases treated by eithe...
Anterior tooth crown fracture in children is something that each dentist will confront many times during his professional career.We studied the prevalence of anterior teeth crown fractures between 7-14 years old students in Tehran and some relevant factors like sex, age, the traumatized tooth, amount of overbite and overjet, upper lip coverage, jaw that had fractured tooth or teeth and place of...
conclusions managing such patients needs a proper transport facility, proper care during transport, appropriate evaluation in the hospital and prompt conservative or operative treatment. treatment is usually safe and effective by well trained professionals with good clinical and radiological outcomes. patients and methods thirty patients (22 males, 8 females) with upper cervical spine injuries ...
hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. we present the case of a 26 year old patient involved in motor vehicle accident. clinical and imaging (radiography, ct) examination revealed an intertrochanteric fracture associated with ipsi...
in vitro effect of fiber reinforcement on fracture resistance of incisal edge composite restorations
objective: introduction of fiber-reinforced composites (frc) greatly enhanced the restoration of fractured anterior teeth. the purpose of this study was to assess the effect of fiber reinforcement on fracture resistance of incisal edge composite restorations of variable thicknesses. methods: forty extracted sound human maxillary incisors were divided into four groups of 10. incisal reduction wa...
The onshore oil and natural gas industries of China have started a large-scale development when crude oil reserves have been difficult to recover. The stratum fracture modification is an indispensable measure to efficiently develop oil and gas fields. Hydraulic fracturing is the most important reservoir stimulation technique, but it is still faced with various problems such as the failure to fr...
The fracture mechanics examines the development and expansion of cracks in solids and how they affect the deformation of materials. The stress intensity factors at the tip of the crack and the critical stress intensity factors or fracture toughness of materials are considered in the relevant criteria. There are three main modes of applying forces to a crack including the tensile mode, shear mod...
conclusions higher age of cyclists and increasing speed of the accident opponent significantly increase the likelihood of sustaining facial fractures. the use of bicycle helmets does not significantly reduce the incidence of mid-facial fractures, while being correlated with an even increased incidence of mandibular fractures. background the effectiveness of bicycle safety helmets in preventing ...
introduction there is very limited literature describing the association of lateral condyle mass (lcm) fracture of the distal humerus associated concurrently with olecranon fracture. herein, a case is reported of a displaced lcm fracture with displaced olecranon fracture, due to complex trauma while getting out of a vehicle, which was managed by open reduction and internal fixation. conclusions...
fracture system in carbonate reservoirs is very complex. understanding the features of fractures such as dip, strike and the other parameters can help to distinguish the behaviour of reservoir in any exploration and production plan. image log is the best way to investigate feature planes like fracture and bedding. image log in one of drilled well #10x393 of bangestan reservoir in gachsaran oilf...
