However, the present experimental results to 300掳C confirmed that two types of brittle fracture exist and that the fracture type changes when the compressive strength becomes equal to the frictional strength. This tends to confirm previous speculations that many crustal fractures are of the high-...
(DFM) can deal with large-scale fractures explicitly and provide higher numerical simulation accuracy. However, due to the complex geometry of the fracture network, it is very difficult to generate the required unstructured conforming mesh, which makes DFM complex and inflexible in dealing with ...
Among the types of orthopedic hardware such as pins, screws and plates, external fixators, intramedullary nail (IMN), and prostheses, pins are the simplest orthopedic devices for fixing fractures which brought about a great transformation in the field of orthopedics [7, 8]. Over the years, vari...
Comparison of minimally invasive surgery for non-flail chest rib fractures: a prospective cohort study Background: To evaluate therapeutic efficacy of minimally invasive and small incision surgery [minimally invasive surgery (MIS)] in patients with non-flail... Y Li,E Gao,Y Yang,... - 《Journa...
Objective To assess the effects of closed reduction with percutaneous pinning and open reduction with pinning for treatment of children with type Ⅲ supracondyla fractures.Methods Data sources were studied and identified by using the Pubmed Medline database,Ovid Medline database and CNKI database,scan...
The biomechanical capacity of “Barrel Hoop Plate (BHP)” in the treatment of the posterolateral tibial plateau (PL) depression fractures remains unknown. In this study, two kinds of posterolateral tibial plateau depression models involving mild slope-type depression fracture (MSDF) and local sink ho...
The position of the second cuneiform is crucial to the integrity of the transverse arch of the foot. Proper initial treatment of these fractures includes precise reduction and stable fixation via open or closed methods so that the second metatarsal is restored as the tenon within a solid mortise...
Ciliated cells have tiny hairs (cilia) on their surface. There are multiple ciliated cells inside the nasal passage which can trap foreign particles (dust, germs, etc.) and effectively 'sweep' them to the back of the throat. Smell receptors are also present around the nasal passage to help...
7 Reasons for the global device recall of Navion were 11 structural failures between one and four years of follow up (e.g., type IIIb endoleaks, fractures and loss of seam integrity, stent ring enlargement).7 The present findings are comparable with previous porcine ex vivo studies and show...
