Economic Analysis of Bisphosphonate Use after Distal Radius Fracture for Prevention of Hip Fracture
Background: Osteoporosis is a common condition among the elderly population, and is associated with an increased risk of fracture. One of the most common fragility fractures involve the distal radius, and are associated with risk of subsequent fragility fracture. Early treatment with bisphosphonates has been suggested to decrease the population hip fracture burden. However, there have been no p...
متن کاملprediction of the subsurface crack growth lifetime in railroad wheel of the iranian railway system
in the last decade, decrease of the wear rate, increase in the axel load, and the velocity of the trains have changed the main damage mechanism of railway wheels from wear to rolling contact fatigue (rcf). rcf may lead to surface and subsurface cracks. the interaction between wear and rcf, removes the surface cracks, but the subsurface crack propagate gradually, and may lead to deeper and more ...
متن کاملApplication of New Front-end Electronics for Non-destructive Testing of Railroad Wheel Sets
For more than 6 years, the automated ultrasonic and eddy-current systems for the inspection of railroad wheel sets, developed by Fraunhofer IZFP and Fraunhofer TEG, have been field-hardened through daily operation at various maintenance facilities of the Deutsche Bahn (DB). The testing stations are equipped with IZFP’s multi-channel electronics, a modular PC integrated system operating inside 1...
متن کاملRecurrent hip fracture prevention with osteoporosis management
Abstract Background: Osteoporosis is a major public health threat, and hip fracture is a serious consequence of osteoporosis. Apatient with an osteoporosis-related hip fracture has an increased risk for a second hip fracture. The effect of osteoporosis management on the risk of recurrent hip fracture was evaluated in this study. Methods: 58 hip fracture patients older than 50yr and BMD < 2.5 w...
متن کاملStructural Health Monitoring of Railroad Wheels Using Wheel Impact Load Detectors
This paper proposes two quantitative criteria for removing railroad wheels from service, based on real-time structural health monitoring trends that are developed using data collected from trains while in-service. The data is collected using Wheel Impact Load Detectors (WILDs). These impact load trends are able to distinguish wheels with a high probability of failure from high impact wheels wit...
