Translation of biomechanical concepts in bone tissue engineering: from animal study to revision knee arthroplasty

Dominique Pioletti, Alexandre Terrier, Brigitte Jolles-Haeberli, Alireza Roshan Ghias

Bone defects in revision knee arthroplasty (RKA) are often located in load-bearing regions. The goal of this study was to determine if a physiologic load could be used as an in situ osteogenic signal to the scaffolds filling the bone defects. In order to a ...

Development and experimental validation of a finite element model of total ankle replacement

Alexandre Terrier, Xavier Crevoisier, Xabier Larrea

Total ankle replacement remains a less satisfactory solution compared to other joint replacements. The goal of this study was to develop and validate a finite element model of total ankle replacement, for future testing of hypotheses related to clinical is ...

Benefit of Cup Medialization in Total Hip Arthroplasty is Associated With Femoral Anatomy

Alexandre Terrier, Francesc Levrero Florencio

Medialization of the cup with a respective increase in femoral offset has been proposed in THA to increase abductor moment arms. Insofar as there are potential disadvantages to cup medialization, it is important to ascertain whether the purported biomechan ...

FE modeling of micromotion at the bone-implant interface

Denis Stauffer

Nowadays, pain and mobility issues of the hip such as arthritis bring more and more people to go through a hip replacement. The primary stability of an implant is essential for the long-term success of hip arthroplasty. Excessive micromotion is an indicato ...

The Relationship between PSD-95 Clustering and Spine Stability In Vivo

Graham Knott, Bohumil Maco

The appearance and disappearance of dendritic spines, accompanied by synapse formation and elimination may underlie the experience-dependent reorganization of cortical circuits. The exact temporal relationship between spine and synapse formation in vivo re ...

Quantitative estimation of foot-flat and stance phase of gait using foot-worn inertial sensors

Kamiar Aminian, Xavier Crevoisier, Hossein Rouhani, Benoît Mariani

Time periods composing stance phase of gait can be clinically meaningful parameters to reveal differences between normal and pathological gait. This study aimed, first, to describe a novel method for detecting stance and inner-stance temporal events based ...

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 ...

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

Younouss Faye

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 ...
