Residual hip dysplasia in children: osseous and cartilaginous acetabular angles to guide further treatment-a pilot study
Purpose In case of residual hip dysplasia (RHD) in children, pelvic radiographs are sometimes insufficient to precisely evaluate the entire coverage of the femoral head, when trying to decide on the need for further reconstructive procedures. Methods This ...
BMC2019Biomechanical effects of passive hip springs during walking
Passive spring-like structures can store and return energy during cyclic movements and thereby reduce the energetic cost of locomotion. That makes them important components of the human body and wearable assistive devices alike. This study investigates how ...
2019Effect of changes of femoral offset on abductor and joint reaction forces in total hip arthroplasty
Alexandre Terrier, Adeliya Latypova, Hannes Andreas Rüdiger, Maïka Réane Guillemin
Anatomical reconstruction in total hip arthroplasty (THA) allows for physiological muscle function, good functional outcome and implant longevity. Quantitative data on the effect of a loss or gain of femoral offset (FO) are scarce. The aim of this study wa ...
Springer Verlag2017Impact of the Femoral Head Position on Moment Arms in Total Hip Arthroplasty: A Parametric Finite Element Study
Alexandre Terrier, Valérie Parvex
Background: Although the importance of accurate femoral reconstruction to achieve a good functional outcome is well documented, quantitative data on the effects of a displacement of the femoral center of rotation on moment arms are scarce. The purpose of t ...
Elsevier2016Impact of individual anatomy on the benefit of cup medialisation in total hip arthroplasty
Alexandre Terrier, Hannes Andreas Rüdiger, Valérie Parvex
Introduction: In total hip arthroplasty, cup medialisation with compensatory increase of femoral offset has been proposed to increase the moment arms of abductor muscles. However, this technique is associated with a loss of acetabular bone stock. Previous ...
Wichtig Publishing2016Benefit 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 ...
Lippincott, Williams & Wilkins2014FPM SIMULATIONS OF A HIGH SPEED WATER JET VALIDATION WITH CFD AND EXPERIMENTAL RESULTS
François Avellan, Ebrahim Jahanbakhsh, Christian Vessaz
The present paper reports the development of Finite Particle Method (FPM) in the framework of a high-speed water jet simulation. The FPM kernel is used to improve the consistency of standard SPH for non-uniform particle distribution. The time integration i ...
Springer2014Sensitivity of hip tissues contact evaluation to the methods used for estimating the hip joint center of rotation
Daniel Thalmann, Ronan Boulic, Jérôme Schmid, Ehsan Arbabi
Computer-based simulations of human hip joints generally include investigating contacts happening among soft or hard tissues during hip movement. In many cases, hip movement is approximated as rotation about an estimated hip center. In this paper, we inves ...
Springer-Verlag2012Importance of polyethylene thickness in total shoulder arthroplasty: A finite element analysis
Dominique Pioletti, Alexandre Terrier, Alain Farron, Vittoria Brighenti
Background: Articular surfaces reconstruction is essential in total shoulder arthroplasty. Because of the limited glenoid bone support, thin glenoid component could improve anatomical reconstruction, but adverse mechanical effects might appear. Methods: Wi ...
Elsevier2012Finite element analysis of knee squat with an osteochondral defect
In this work a 3D musculoskeletal model of the knee joint, that can simulate a squat movement, has been developed. Such a model would be useful to understand the biomechanics of the knee. The model consisted of all the the bones with their articular surfac ...
