Numerical model of the ankle joint for the study of total ankle replacement

Total ankle replacement (TAR) is a successful short-term procedure but after ten years the implants have low survival rates involving numerous complications. Today the mechanism that leads to the failure of TAR remains unclear. Therefore there is a need a ...

Design and test of a MEMS strain-sensing device for monitoring artificial knee implants

Kamiar Aminian, Philippe Renaud, Alexandre Terrier, Arnaud Bertsch, Arash Arami, Willyan Hasenkamp Carreira

This paper describes the development of a polyimide-based MEMS strain-sensing device. Finite element analysis was used to investigate an artificial knee implant and assist on device design and to optimize sensing characteristics. The sensing element of the ...

Soft tissue artifact assessment during treadmill walking in subjects with total knee arthroplasty

Jean-Philippe Thiran, Kamiar Aminian, Arnaud Barré

Accurate measurement of knee kinematics during functional activities suffers mainly from soft tissue artifact (STA): the combination of local surface deformations and rigid movement of markers relative to the underlying bone (also called rigid STA movement ...

Development of an Assistive Motorized Hip Orthosis

Hannes Bleuler, Reymond Clavel, Mohamed Bouri, Jeremy Olivier, Amalric Louis Ortlieb

With the increase of life expectancy, a higher number of elderly need assistance to maintain their mobility and their independance. The hip joint is crucial for walking and is problematic for a large number of aged people. In this paper we present a novel ...

A Novel Approach to Reducing Number of Sensing Units for Wearable Gait Analysis Systems

Kamiar Aminian, Brigitte Jolles-Haeberli, Arash Salarian

Gait analysis methods to estimate spatiotemporal measures, based on two, three or four gyroscopes attached on lower limbs have been discussed in the literature. The most common approach to reduce the number of sensing units is to simplify the underlying bi ...

Effect of a pathological scapular tilt after total shoulder arthroplasty

Dominique Pioletti, Alexandre Terrier, Alain Farron

Total shoulder arthroplasty (TSA) is an accepted and most successfully used treatment for different shoulder pathologies. Different risk factors for the failure of the prosthesis are known. A pathological scapular orientation, observed in elderly people or ...

Remote Powering and Wireless Communication of a Smart Knee Prosthesis

Oguz Atasoy

With the advance in microelectronics and microsystems, better instruments in every domain are designed and built. For many years, scientists have tried to understand nature, and engineers to mimic the perfect design. One example of this is the human knee, ...

A thin-layer interface model for wave propagation through filled rock joints

Jian Zhao, Wei Wu, Jianbo Zhu

The present study essentially employs a thin-layer interface model for filled rock joints to analyze wave propagation across the jointed rock masses. The thin-layer interface model treats the rough-surfaced joint and the filling material as a continuum med ...

Relationship between interfacial micromotion and bone density around cementless hip implant

Valérie Parvex

The hip is one of the most injured joint in the body with ageing. Osteoarthritis and degenerative diseases often lead to the necessity of a total hip arthroplasty in order to reduce pain and increase mobility. The advantage of cementless implants resides i ...

Importance of the subscapularis muscle after total shoulder arthroplasty

Dominique Pioletti, Alexandre Terrier, Alain Farron, Valérie Hélène Emilie Malfroy Camine, Xabier Larrea

Background: The rotator cuff muscles are the main stabilizer of the glenohumeral joint. After total shoulder arthroplasty using anterior approaches, a dysfunction of the subscapularis muscle has been reported. In the present paper we tested the hypothesis ...
