Instrumented Knee Prosthesis for Force and Kinematics Measurements

Kamiar Aminian, Philippe Renaud, Pierre-André Farine, Peter Ryser, Catherine Dehollain, Arnaud Bertsch, Brigitte Jolles-Haeberli, Eric Meurville, Arash Arami, Steve Tanner, Willyan Hasenkamp Carreira, Shafqat Ali, Oguz Atasoy, Matteo Simoncini

In this work, we present the general concept of an instrumented smart knee prosthesis for in-vivo measurement of forces and kinematics. This system can be used for early monitoring of the patient after implantation and prevent possible damage to the prosth ...

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 ...

Amputation and prosthesis implantation shape body and peripersonal space representations

Andrea Serino, Elisa Canzoneri

Little is known about whether and how multimodal representations of the body (BRs) and of the space around the body (Peripersonal Space, PPS) adapt to amputation and prosthesis implantation. In order to investigate this issue, we tested BR in a group of up ...

A numerical model of the ankle to analyze joint prostheses

Valérie Parvex

The ankle is one of the most injured joint in the body. However, it remains a new field of study in biomedical orthopedics. With the increased life span, more people suffer from arthosis and joint problems. That is why the improvements done in arthroplasty ...

LTCC-Based Sensors for Mechanical Quantities

Thomas Maeder, Carolin Lohrberg

Besides their excellent dielectric and thermo-mechanical characteristics Low Temperature Cofiring Ceramics (LTCC) are also well suited for the fabrication of 3D micromechanical components such as sensors for mechanical quantities. This paper describes the ...

Numerical analysis of a 3-screws baseplate for reverse shoulder arthroplasty

Anouk Grandgeorge

Reverse shoulder arthroplasty has become the classical treatment for glenohumeral joint arthritis associated with rotator cuff dysfunction. The design of the prosthesis, the fixation of the implant and the surgical technique are however still to be improve ...

Tightening force and torque of nonlocking screws in a reverse shoulder prosthesis

Dominique Pioletti, Alexandre Terrier, Alain Farron, Francesco Merlini, Miguel Gortchacow, Stephanie Kochbeck

Background. Reversed shoulder arthroplasty is an accepted treatment for glenohumeral arthritis associated to rotator cuff deficiency. For most reversed shoulder prostheses, the baseplate of the glenoid component is uncemented and its primary stability is p ...

A musculoskeletal shoulder model based on pseudo-inverse and null-space optimization

Dominique Pioletti, Denis Gillet, Alexandre Terrier, Alain Farron, Philippe Müllhaupt, Yvan Michellod, Martin Aeberhard

The goal of the present work was assess the feasibility of using a pseudo-inverse and null-space optimization approach in the modeling of the shoulder biomechanics. The method was applied to a simplified musculoskeletal shoulder model. The mechanical syste ...

Comparison of polyethylene wear in anatomical and reversed shoulder prostheses

Dominique Pioletti, Alexandre Terrier, Alain Farron, Francesco Merlini

Wear of polyethylene is associated with aseptic loosening of orthopaedic implants and has been observed in hip and knee prostheses and anatomical implants for the shoulder. The reversed shoulder prostheses have not been assessed as yet. We investigated the ...

Strength of the baseplate fixation of a reversed shoulder prosthesis

Stephanie Kochbeck

A reversed shoulder prosthesis is the general treatment of glenohumeral arthritis and concomitant rotator cuff arthropathy. However, failure due to loosening of the components remains a concern. The purpose of this study was to examine the forces that occu ...
