BACKGROUND Insufficient cement distribution (ICD) in the fractured area has been advocated to be responsible for unsatisfied pain relief after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCFs). However, little is known about risk factors for the occurrence of ICD. OBJECTIVE The present study aimed to identify independent risk factors of the emergence o...

To investigate the association of polymorphisms within candidate genes which we hypothesized may contribute to stress fracture predisposition, a case-control, cross- sectional study design was employed. Genotyping 268 Single Nucleotide Polymorphisms- SNPs within 17 genes in 385 Israeli young male and female recruits (182 with and 203 without stress fractures). Twenty-five polymorphisms within 9...

We present an experimental approach for investigating the potential for bioremediation of Ž . volatile organic compounds VOCs in fractured rock vadose zones. The experimental work was performed with rock samples and indigenous microorganisms from the site of the United States Ž . Department of Energy’s Idaho National Engineering and Environmental Laboratory INEEL , located in a basalt flow basi...

Ageing is accompanied by reduced functioning of the immune system, termed immunesenescence which is associated with increased risk of infection and mortality. However the immune system does not operate in isolation and can be modified by many environmental factors, including stress. In this study we determined whether physical stress (hip fracture) and psychological distress (depressive symptom...

introduction: vertical root fracture (vrf) is common in endodontically treated teeth. conventional and digital radiographies have limitations for detection of vrfs. cone-beam computed tomography (cbct) offers greater detection accuracy of vrfs in comparison with conventional radiography. this study compared the effects of metal artifacts on detection of vrfs by using two cbct systems. methods a...

BACKGROUND We characterize in this report the mechanism and type of skull fracture in urban populations of Iran. METHODS Data including the general characteristics, mechanism of trauma, abbreviated injury scale, Glasgow coma scale, duration of hospitalization, and outcome of trauma patients registered from 1999 to 2004 were extracted from the Iranian National Trauma Registry database. RESUL...

Min Ma National University of Defense Technology Department of Astronautical Technology Changsha, 410073, China Abstract. A single fringe phase shifting technique is presented for extracting the whole-field displacement distribution from single fringe patterns. By making a small modification in the traditional Fourier transform (FFT) method for fringe processing, the proposed method is capable ...

BACKGROUND Lack of fracture movement could be a potential cause of periprosthetic femoral fracture (PFF) fixation failures. This study aimed to test whether the use of distal far cortical locking screws reduces the overall stiffness of PFF fixations and allows an increase in fracture movement compared to standard locking screws while retaining the overall strength of the PFF fixations. METHOD...

8 [1] In this paper we quantify the influence of geometry and 9 distribution of surface roughness to the directional 10 anisotropy of fluid flow and transport properties of a 11 single fracture. Roughness of fractures appears to have first 12 order control on how they behave mechanically and 13 hydraulically. We directly quantified the surface roughness 14 of a single fracture using high-resolu...
