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...

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...

Define shoulder instability and identify the most common causes of shoulder instability in athletes. Shoulder instability encompasses a wide spectrum, from complete dislocations that require manual reduction to microinstability in throwers. When we looked prospectively at West Point cadets, we found that 80% of instability events were subluxations (no manual reduction performed).1 We found that...

Elite Indian athletes who were undergoing training at the NIS, Patiala for the preparation of IX Asian Games held in Delhi in 1982, suffered 317 injuries during the 14 months of training. Of the injuries 64 per cent were observed in males, while 36 per cent were observed in females. Most of the injuries seen were in the lower limbs (59.2 per cent) and when classified according to the tissues in...

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...
