Biomechanical and Finite Element Analyses of Alternative Cements for use in Vertebral Kyphoplasty
A vertebral compression fracture occurs when the vertebral body of the spine collapses due to osteoporosis or trauma. Depending on the degree of osteoporosis, the forces required to induce vertebral compression fracture can vary while the forces required to induce fractures via trauma are large. …

The effect of pressure and temperature on the microstructure and mechanical properties of polycrystalline graphites
… electron microscopy were used to examine their fracture surfaces and macro porosity. Mercury porosimetry provided a means of establishing the pore size distribution of pores of less than 20 1-1m diameter. Bulk and skeletal densities were determined from mercury porosimetry and helium pycnometry …

The Use of a Tuning Fork and Stethoscope Versus Clinical Fracture Testing in Assessing Possible Fractures
Traditional fracture testing in the field of athletic training relies heavily on subjective responses of the athlete. Percussion and compression type tests rely on the athlete stating an increase in pain which represents a positive symptom of a possible fracture. The tuning fork and stethoscope …

Genetic Association Study of Osteoporotic Vertebral Compression Fractures in Postmenopausal Women
… VEGF is also known to promote the healing of fractures and hyperhomocysteinemia is associated with the risk of skeletal health problems, such as osteoporosis, low body mineral density, and fracture. 5, 10-Methylenetetrahydrofolate reductase (MTHFR) and thymidylate synthase (TS) are involved in …

Effect of Vertebroplasty with Bone Filler Device and Comparison with Balloon Kyphoplasty
… popular procedures for osteoporotic vertebral compression fractures. Although the kyphoplasty has a superior effect, it destroys normal vertebral trabecular structure and it has a higher cost. PURPOSE: To analyze vertebroplasty with a bone filler device compared with conventional kyphoplasty. …

Hierarchical Assembly Strategy and Multiscale Structural Origin of Exceptional Mechanical Performance In Nacre
… <p>Particularly fascinating is the fracture toughness enhancement of nacre through exquisitely collecting mechanically inferior calcium carbonate (CaCO3) and biomolecules. The sandwich-like microarchitecture with a geometrically staggered arrangement can induce crack deflection along …
