Crack nucleation has been the subject of important contributions in two last decades. Starting from double criterion Leguillon (Eur J Mech A 21:61–72, 2002), present paper suggests that an energy is sufficient for prediction loading level triggers as well its geometrical characteristics. In view application to saturated porous materials, role pore fluid during considered. case low compressibili...

conclusions in this experimental model of open fracture, the chitosan film pure or impregnated with ciprofloxacin was not effective in the prophylaxis of osteomyelitis. results in cultures of the ct group, there was less bacterial growth compared to the results of the cultures of the ic (p = 0.005), c (p = 0.005) and ca (p = 0.009) groups. the inflammation was lower in the ct group compared to ...

INTRODUCTION Post-traumatic osteoarthritis (PTOA) is the unfortunate outcome of many high-energy fractures of the tibial plafond. The severity of the fracture is a major risk determinant. The inability to objectively quantify fracture severity has confounded efforts to determine the efficacy of different treatments aimed at preventing the PTOA development. A CTbased measure of fracture energy w...

Background: The World Health Organization suggested that frailty is a critical indicator influencing successful aging. Previous studies have indicated a high correlation between frailty and bone fracture in older adults. However, few studies have investigated the correlation between the various stages of frailty with bone fracture risk. Purpose: This study investigated the correlation between f...

BACKGROUND Hip fracture is commonly associated with an overwhelming inflammatory response, which may lead to high rates of morbidity and mortality in the elderly. MicroRNAs (miRNAs) play important roles in the functions of immune system. However, the association between miRNA dysregulation and immune disturbance (IMD) related to elderly hip fracture is largely unknown. METHODS In this study, ...

PURPOSE The purpose of this study was to analyze fracture patterns and the magnitude of displacement in the distal radioulnar joint (DRUJ), by three-dimensional (3D) computed tomography (CT), for distal radius fractures with intra-articular displacement of the radiocarpal joint. METHODS We reconstructed 3D images for 72 consecutive patients with displaced intra-articular distal radius fractur...
