Scattering amplitude of a single fracture under uniaxial stress

Remotely sensing the properties of fractures has applications ranging from exploration geophysics to hazard monitoring. Newly developed capabilities to measure the in-plane component of dense laser-based ultrasound wave fields allow us to test the applicab ...

Theoretical bounds for the influence of tissue-level ductility on the apparent-level strength of human trabecular bone

Frédéric Edouard Juillard

The role of tissue-level post-yield behavior on the apparent-level strength of trabecular bone is a potentially important aspect of bone quality. To gain insight into this issue, we compared the apparent-level strength of trabecular bone for the hypothetic ...

Influence of the moisture content on the fracture characteristics of welded wood joint. Part 1: Mode I fracture

John Botsis, Joël Cugnoni, Parviz Navi, Martin Rhême

Friction welding is a joining technique for wood materials. The positive aspects of this technique are the speed of processing and the absence of chemical or mechanical agents, but the welded joints are not water resistant. To understand better the effect ...

Cement distribution in vertebroplasties: imaging and simulation

Vincent Stadelmann

Prophylactic vertebroplasty, the percutaneous injection of bone cement into a weak vertebral body (VB), has been shown to reinforce the bone and possibly to minimize fracture risks. Cement leakage is still a common occurrence that can cause severe complica ...

Simulation of postoperative scapula fractures after rTSA

Alice Ghislaine Concordel

Reverse total shoulder arthroplasty (rTSA) is recommended in case of severe muscle deficiency, along with important joint wear. Although having a correct placement of the prosthesis after the operation and a recovery of the mobility, several cases of scapu ...

Theory and laboratory experiments of elastic wave scattering by dry planar fractures

Thomas Emmanuel Blum

Remote sensing of fractures with elastic waves is important in fields ranging from seismology to nondestructive testing. In many geophysical applications, fractures control the flow of fluids such as water, hydrocarbons or magma. While previous analytic de ...

Laser Excitation of a Fracture Source for Elastic Waves

Thomas Emmanuel Blum

We show that elastic waves can be excited at a fracture inside a transparent sample by focusing laser light directly onto this fracture. The associated displacement field, measured by a laser interferometer, has pronounced waves that are diffracted at the ...

Effects of Tissue-Level Ductility on Trabecular Bone Strength

Frédéric Edouard Juillard

Osteoporosis is one of the most common skeletal diseases that lead to an accelerated bone loss due to an imbalance in bone turnover. This low bone mass and degraded bone microarchitecture cause a reduction in mechanical properties and an associated increas ...

Bone regeneration and stem cells

Dominique Pioletti

This invited review covers research areas of central importance for orthopaedic and maxillofacial bone tissue repair, including normal fracture healing and healing problems, biomaterial scaffolds for tissue engineering, mesenchymal and foetal stem cells, e ...

Engineering of living autologous human umbilical cord cell-based septal occluder membranes using composite PGA-P4HB matrices

Peter Modregger, Marco Stampanoni

Interventional closure of intracardiac wall defects using occluder devices has evolved as a highly attractive treatment option. However, incomplete and delayed healing reactions often result in a major risk of residual defects, thromboembolism, or device f ...
