Contemporary locking plates promote biological fixation through indirect reduction techniques and by elevating the plate from the bone. They have improved fixation strength in osteoporotic bone. Periarticular locking plates are rapidly being adopted for bridge plating of periprosthetic femur fractures. When these plates are used for indirect reduction and bridge plating osteosynthesis, fracture...
This article takes a single-tower cable-stayed bridge with steel-UHPC composite deck steel box girder as the research object and develops different casting plans for UHPC layer on deck. It analyzes influence of factors such block sequence deck, whether or not to set up post-casting section, counterweights range it additional deformation stress formed during construction stage, exploring impact ...
We treated 15 patients with atrophic nonunion of a diaphyseal fracture of the humerus with an associated bony defect using an autogenous cancellous bone graft and a plate to bridge the defect. There were nine men and six women with a mean age of 48 years. The mean length of the bony defect was 3 cm. At a mean follow-up of 30 months only one fracture failed to unite. This suggests that, in the p...
PURPOSE The purpose of this study was to investigate the effects of transplantation of an in vitro-generated, scaffold-free, tissue-engineered cartilage tissue analogue (CTA) using a suspension chondrocyte culture in a rabbit growth-arrest model. MATERIALS AND METHODS We harvested cartilage cells from the articular cartilage of the joints of white rabbits and made a CTA using a suspension cul...
The load-bearing performance of a RC simply supported beam bridge was comprehensively detected and evaluated. appearance detection results show that there is large area damaged exposed reinforcement in the main girder diaphragm plate bridge. detecting material condition state parameters durability insufficient, risk steel corrosion large, strength concrete poor. load test bearing capacity does ...
The growth plate is responsible for longitudinal growth of children's long bones. However, being a cartilaginous tissue, the growth plate has a limited ability for regeneration and thus injured growth plate is often repaired by bony tissue resulting in bone growth defects of the involved limb. Understanding the pathophysiology of growth plate bony repair and developing preventative treatments r...
Bridges are often built in locations susceptible to multiple extreme hazards. Meeting some or all of these constraints drives the development of innovative multi-hazard design concepts. This paper presents the results of research conducted to develop and experimentally validate such multi-hazard bridge pier concepts. The first concept is a pier-bent made of concrete filled steel tube columns. F...
Based on Zhonghua Road Bridge in Liaocheng city, a single tower hybrid cable-stayed bridge, the stress of steelconcrete joint girder is studied using finite element method with software MIDAS and ANSYS. The beam model whole bridge established CIVIL, from which internal forces critical sections steel–concrete under six adverse conditions are obtained. Then, results applied refined solid-shell Wi...
A belt-conveyor bridge is built inside a ring-stiffened cylindrical shell. The unknown variables are the shell thickness as well as the thickness and the number of flat rings. Optimum solutions are evaluated for different bridge lengths. The design constraints relate to the local shell buckling strength, to the panel ring buckling and to the deflection of the bridge. The cost function includes ...
