Glenoid bone strain after anatomical total shoulder arthroplasty: In vitro measurements with micro-CT and digital volume correlation

Dominique Pioletti, Alexandre Terrier, Alain Farron, Yasmine Boulanaache

Glenoid implant loosening remains a major source of failure and concern after anatomical total shoulder arthroplasty (aTSA). It is assumed to be associated with eccentric loading and excessive bone strain, but direct measurement of bone strain after aTSA i ...

Additive manufacturing of hierarchical injectable scaffolds for tissue engineering

Philippe Renaud, Niccolo Piacentini, Thomas Michael Braschler, Ariane Rochat

We present a 3D-printing technology allowing free-form fabrication of centimetre-scale injectable structures for minimally invasive delivery. They result from the combination of 3D printing onto a cryogenic substrate and optimisation of carboxymethylcellul ...

Helium effects on irradiation assisted stress corrosion cracking susceptibility of 316L austenitic stainless steel

Ignasi Villacampa Roses

The formation and growth of cracks by irradiation assisted stress corrosion cracking (IASCC) in light water reactor internals is a critical issue for a safe long-term operation of nuclear power plants. The IASCC susceptibility at relatively low dose is dom ...

20 Hz X-ray tomography during an in situ tensile test

Andreas Mortensen

This paper describes an in-situ tensile test in synchrotron tomography achieved for the first time with a frequency of 20 tomograms per second (20 Hz acquisition frequency). This allows us to capture rapid material fracture processes, such as that of a met ...

Following dislocation patterning during fatigue

Helena Van Swygenhoven, Steven Van Petegem, Nicolò Grilli, Ainara Irastorza Landa

Precursors of failure are dislocation mechanisms at the nanoscale and dislocation organization at the mesoscale responsible for long-range internal stresses and lattice rotation. Detailed information on the link between both scales is missing, computationa ...

Time course of bone screw fixation following a local delivery of zoledronate in a rat femoral model – a micro-finite element analysis

Dominique Pioletti, Alexandre Terrier, Ulrike Kettenberger, Adeliya Latypova

A good fixation of osteosynthesis implants is crucial for a successful bone healing but often difficult to achieve in osteoporotic patients. One possible solution to this issue is the local delivery of bisphosphonates in direct proximity to the implants, A ...
