Atomic aluminum content (x) effect on fretting-corrosion of Ti1-xAlxN coatings for orthopedic applications

Normal micro-movements at the bone-implant interface originate fretting-corrosion processes, thus releasing wear debris from the bone and metallic devices and compromising the fixability of the implant. Titanium aluminum nitride (Ti1-xAlxN) coatings have b ...

Finite element modelling of micromotion at the bone-implant interface

Madge Audrey Marie Martin

A good implant primary stability is closely associated with long-term success of total hip arthroplasty. Excessive interfacial micromotion around the femoral component after cementless hip replacement is related to aseptic loosening of the stem and affects ...

Adverse tissue reaction to corrosion at the neck-stem junction after modular primary total hip arthroplasty

Stefano Mischler, Pierre Mettraux

Complications related to the neck-stem junction of modular stems used for total hip arthroplasty (THA) are generating increasing concern. A 74-year-old male had increasing pain and a cutaneous reaction around the scar 1 year after THA with a modular neck-s ...

Tribocorrosion of passive metals in the mixed lubrication regime: theoretical model and application to metal-on-metal artificial hip joints

Stefano Mischler, Shoufan Cao

Wear is a key problem limiting the lifetime and performance of total hip arthroplasty. The synovial fluid, acting as lubricant, can alleviate the wear of implants but also introduces corrosion. The interaction of mechanical wear and electrochemical corrosi ...

Development of an in situ controllable polymerization tool and process for hydrogel used to replace nucleus pulposus

Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Andreas Schmocker, Azadeh Khoushabi

Currently implants or tissue replacements are inserted either as a whole implant or by injecting a liquid which polymerizes to form a solid implant at the appropriate location. This is either highly invasive or not controllable. We developed a tool to perf ...

Finite element modelling of the bone-implant interface and experimental validation

Céline Samira Wyss

Excessive interfacial micromotion endangers the implant primary stability by favoring the formation of a fibrous tissue layer at the bone-implant interface. It was recently proposed that implant micromotion induces fluid flow in the granulation tissue that ...

A patient-specific numerical musculoskeletal knee model

Adeliya Latypova

Total Knee Arthroplasty (TKA) is a well-accepted surgical treatment of severe cases of osteoarthritis. Surgery is associated with improved pain level, knee function and health-related quality of life. Despite advances in surgical techniques and implant des ...

Mobilities after the car

Alexandre André Robert Rigal, André Ourednik, Jade Rudler

For many, the self-evident use of the car blends out other possible mobilities. We seek a way to unfold the future by questioning other ways of moving around and living. In order to do so, we consider automobility as a problem to which solutions can be fou ...

Design guidelines for concentrated photo-electrochemical water splitting devices based on energy and greenhouse gas yield ratios

Sophia Haussener, Mikaël Dumortier

Device and system design choices for solar energy conversion and storage approaches require holistic design guidelines which simultaneously respect and optimize technical, economic, sustainability, and operating time constraints. We developed a simulation ...

In vivo electrochemical corrosion study of a CoCrMo biomedical alloy in human synovial fluids

Stefano Mischler

The present study was initiated with the aim to assess the in vivo electrochemical corrosion behaviour of CoCrMo biomedical alloys in human synovial fluids in an attempt to identify possible patient or pathology specific effects. For this, electrochemical ...
