Shaft sinking is one of the main parts in underground mine planning. Shaft has various applications in underground mines e.g. minerals exiting flow, gases entrance or exit way, stope developments for exploitation etc. Considering that this section requires an abundance of expenses, management always following the election is the way that both terms have the technical considerations, economic co...

Radial nerve palsy, either axonotmesis or neurapraxia, associated with fractures of the shaft humerus occurred in about 10 percent of the patients with humeral shaft fractures [1,2,3]. Its close relation to the humerus, especially fractures of the middle and the distal thirds of the humerus makes the radial nerve vulnerable to such injuries [4,5,6]. There are many debate about the management of...

BACKGROUND Long-stem tibial components are available for complex primary and revision total knee arthroplasties. Most of the stems' designs are based on anatomic data from Western populations. We conducted a morphologic study to determine the relationship of the tibial shaft to the tibial plateau in Chinese people. METHODS We included knees from fifty Chinese individuals (twenty-five females ...

BACKGROUND Humeral shaft fractures account for 1 to 3% of all fractures in adults and for 20% of all humeral fractures. Non-operative treatment is still the standard treatment of isolated humeral shaft fractures, although this method can present unsatisfactory results. Surgical treatment is reserved for specific conditions. Modern concepts of internal fixation of long bone shaft fractures advoc...

conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...

conclusions the lack of difference between adma levels in patients with pa and eh suggests that endothelial dysfunction is more likely related to hypertension per se than to the specific etiology of elevated blood pressure. results patients with pa had significantly higher concentrations of adma than healthy controls (0.488 ± 0.085 vs. 0.433 ± 0.053 μmol/l, p = 0.027). no difference was found i...

BACKGROUND Footballers constitute a unique group of patients with tibial shaft fractures. They tend to have excellent general health and well developed musculature in the leg, and their fractures are generally closed injuries caused by low velocity trauma. However, little has been reported on the outcome after tibial shaft fractures in this group. OBJECTIVE To identify patterns of injury, res...

Minimally invasive plate osteosynthesis (MIPO) has been used for humeral shaft fractures, but concerns exist about soft tissue injuries. The purpose of this study was to report the surgical technique and clinical outcomes of MIPO using a helical plate for metadiaphyseal complex humeral shaft fractures. Twelve patients with acute displacement involving proximal and middle third humeral shaft fra...

Shaft angular acceleration is one of the most important parameter of rotary machines, the error of angular acceleration increased when the shaft speed up. For this problem, a new high accuracy angular acceleration measurement system is presented, the principle of measurement is self-regulating the period of speed sampling signal according to the proportion of the shaft speed up. This measuremen...

Introduction: A bifocal non-union of shaft of radius associated with ipsilateral non-union shaft of ulna in an adult has not been reported in the literature till date to the best of our knowledge, though few similar cases of fresh fractures have been reported. The case being reported by us is the first of its kind. Case Presentation: We report a case of bifocal non-union of shaft radius with no...
