BACKGROUND We studied Y-STRUT® (Hyprevention, France), a new percutaneous internal fixation device, in combination with bone cementoplasty to prevent hip fracture. METHODS Between February 2013 and February 2015, a total of 16 femoral necks in 4 osteoporotic and 12 oncologic patients have been considered for prophylactic consolidation in this prospective multicentre pilot study involving 4 di...

The optic strut and the anterior clinoid process represent bony structures that are closely related to anatomically and clinically significant elements such as the cavernous sinus, the internal carotid artery, the optic nerve and the pituitary gland. The objective of our study was to quantify dimensions of the optic strut and anterior clinoid process, and to determine variations in positions an...

BACKGROUND Three-dimensional design simulations of coronary metallic stents utilizing mathematical and computational algorithms have emerged as important tools for understanding biomechanical stent properties, predicting the interaction of the implanted platform with the adjacent tissue, and informing stent design enhancements. Herein, we demonstrate the hemodynamic implications following virtu...

OBJECTIVES/HYPOTHESIS This experimental study in a rabbit model aimed to investigate the use of glass ionomer cement as a tissue adhesive on the dorsal L-strut. STUDY DESIGN Sixteen adult male New Zealand White rabbits were used. The rabbits were equally divided into two groups as the control and the study groups. METHODS The nasal septum was exposed through a superior approach. A graft was...

Purpose We evaluated the medium- to long-term outcomes of cortical strut allografts used to treat periprosthetic bone defects to better understand the correlation between radiological and clinical outcomes. Materials and Methods We retrospectively reviewed outcomes from 19 patients undergoing cortical strut allografts to treat periproshtetic bone defects from 2001 to 2015. The mean age at ind...

This paper describes the use of two simple electromagnetic methods for detecting strut fractures in prosthetic heart valves. The first method involves immersing the heart valve in a uniform time varying electromagnetic field and measuring the perturbation of the field in regions proximate to the strut. In vitro tests done to date indicate that the method is capable of discriminating between int...

Legumes have been an integral part of sustainable agriculture for hundreds, if not thousands, of years, and they are likely to become even more important in the future. This is because legumes are able to form nitrogen-fixing symbioses with rhizobia that allow them to grow in the absence of added nitrogen fertilizers. In addition, legumes are able to form mycorrhizal symbioses with fungi that p...

Quasi-static uniform compression tests and low-velocity concentrated impact tests were conducted to reveal the failure mechanisms and energy absorption capacity of two-layer carbon fiber composite sandwich panels with pyramidal truss cores. Three different volume-fraction cores (i.e., with different relative densities) were fabricated: 1.25%, 1.81%, and 2.27%. Two-layer sandwich panels with ide...
