BACKGROUND For internal fixation of AO classification Type B lateral malleolar fracture, insertion of lag screws into the fracture plane and fixation with a one-third tubular plate as a neutralization plate are the standard treatment procedures. The one-third tubular plate is processed to a hook shape and hung on the distal end of the fibula. In this study, to compare the function of the hook a...

[1] Satellite imagery reveals that a series of large icebergs (B15B in April 2001, C19 in June 2003, and B15A in October 2005) broke up or fractured while exiting the Ross Sea in a narrowly defined area off Cape Adare, Antarctica. Examination of recent swath‐mapped bathymetric observations revealed that the principle agent of these breakups is a previously unknown 9 km long ridge with minimum d...

The aim of Instrumented Gait Analysis is to support clinicians’ decision making process concerning diagnosis and treatment strategies. Movement Analysis systems are used to measure data such as joint kinematics or kinetics during gait in a quantitative way. However, data evaluation is performed subjectively by experienced physicians for a specific clinical problem (diagnose individual disabilit...

Effectiveness of cutting is measured by the ability to achieve a desired rate of material fracture. The work performed by a knife overcomes the material toughness to yield fracture, acts against friction between the material and the blade, and generates shape deformation. This paper studies how to control a robotic arm to achieve a desired time profile of material fracture along a prescribed cu...

rails fracture by the growth of fatigue crack or critical crack is one of the prevalent defects in railway. the rail fracture, failure and stress analysis should be studied in order to prevention of rail fracture. in this paper, new formulation of contact stress for two rolling bodies is presented, where the results are closed to the hertz stress formulation. moreover, stress analysis is done b...

BACKGROUND Hip fractures in the older person lead to an increased risk of mortality, poorer quality of life and increased morbidity. Benzodiazepine (BNZ) use is associated with increased hip fracture rate, consequently Z-drugs are fast becoming the physician's hypnotic prescription of choice yet data on their use is limited. We compared the risk of hip fracture associated with Z-drugs and BNZ m...
