This article reviews acute dislocations of the distal radioulnar joint (DRUJ) and distal ulna fractures. Acute dislocations can occur in isolation or in association with a fracture to the distal radius, radial metadiaphysis (Galeazzi fracture), or radial head (Essex-Lopresti injury). Distal ulna fractures may occur in isolation or in combination with a distal radius fracture. Both injury patter...

Understanding the kinematics of the carpus is essential to the understanding and treatment of wrist pathologies. However, accurate measurement of the kinematics of the carpal bones is difficult because they are small bones undergoing complex movements of small amplitudes. As a result, to date, there is no clear consensus on carpal kinematics. Moreover, most studies only investigate single rotat...

we introduce a new concept of general $g$-$eta$-monotone operator generalizing the general $(h,eta)$-monotone operator cite{arvar2, arvar1}, general $h-$ monotone operator cite{xiahuang} in banach spaces, and also generalizing $g$-$eta$-monotone operator cite{zhang}, $(a, eta)$-monotone operator cite{verma2}, $a$-monotone operator cite{verma0}, $(h, eta)$-monotone operator cite{fanghuang}...

background: osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. osteoporosis can be diagnosed easily with the use of dual-energy x-ray absorptiometry (dxa) equipment. the aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine ls in pre- and post-menopausal women from isfaha...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...
