Muscle co-contraction in an upper limb musculoskeletal model: EMG-assisted vs. standard load-sharing

Dominique Pioletti, Philippe Müllhaupt, Alexandre Terrier, Alain Farron, Matteo Mancuso, Ehsan Sarshari

Estimation of muscle forces in over-actuated musculoskeletal models involves optimal distributions of net joint moments among muscles by a standard load-sharing scheme (SLS). Given that co-contractions of antagonistic muscles are counterproductive in the n ...

Predicting Transdermal Fentanyl Delivery Using Mechanistic Simulations for Tailored Therapy

Alexandre Terrier

Transdermal drug delivery is a key technology for administering drugs. However, most devices are "one-size-fits-all", even though drug diffusion through the skin varies significantly from person-to-person. For next-generation devices, personalization for o ...

Predrilled locking compression plate is more accurate than tension band wiring in restoring articular geometry of the ulnar greater sigmoid notch after olecranon Chevron osteotomy

Alexandre Terrier, Frédéric Vauclair, Patrick Goetti

Introduction: The olecranon Chevron osteotomy (OCO) is commonly used to approach complex intraarticular fractures of the distal humerus. Predrilled tension band wiring (TBW) has historically been used to fix OCO. However, clinical outcomes are burdened by ...

Reduction of scapulohumeral subluxation with posterior augmented glenoid implants in anatomic total shoulder arthroplasty: Short-term 3D comparison between pre- and post-operative CT

Alexandre Terrier, Alain Farron, Patrick Goetti

Background: Failure rates in anatomic total shoulder arthroplasty (aTSA) are higher in case of asymmetric glenoid bone loss secondary to posterior wear, and in persistent static posterior subluxation of the humeral head (PSH). ...

Glenoid bone strain after anatomical total shoulder arthroplasty: In vitro measurements with micro-CT and digital volume correlation

Dominique Pioletti, Alexandre Terrier, Alain Farron, Yasmine Boulanaache

Glenoid implant loosening remains a major source of failure and concern after anatomical total shoulder arthroplasty (aTSA). It is assumed to be associated with eccentric loading and excessive bone strain, but direct measurement of bone strain after aTSA i ...

A Robotic Glenohumeral Simulator for Investigating Prosthetic Implant Subluxation

Kamiar Aminian, Alexandre Terrier, Alain Farron, Matteo Mancuso, Arash Arami

Total shoulder arthroplasty (TSA) is an effective treatment for glenohumeral (GH) osteoarthritis. However, it still suffers from a substantial rate of mechanical failure, which may be related to cyclic off-center loading of the humeral head on the glenoid. ...

Automated CT bone segmentation using statistical shape modelling and local template matching

Alexandre Terrier, Philippe Büchler, Alain Farron, Elham Taghizadeh

Accurate CT bone segmentation is essential to develop chair-side manufacturing of implants based on additive manufacturing. We herewith present an automated method able to accurately segment challenging bone regions, while simultaneously providing anatomic ...

Patellar bone strain after total knee arthroplasty is correlated with bone mineral density and body mass index

Dominique Pioletti, Alexandre Terrier, Philippe Büchler, Elham Taghizadeh, Adeliya Latypova

Patella-related complications after total knee arthroplasty (TKA) remain a major clinical concern. Previous studies have suggested that increased postoperative patellar bone strain could be related to such complications, but there is limited knowledge on p ...

Effect of a collar on subsidence and local micromotion of cementless femoral stems: in vitro comparative study based on micro-computerised tomography

Dominique Pioletti, Alexandre Terrier, Valérie Hélène Emilie Malfroy Camine

Purpose The aim of this study is to quantitatively compare the difference in primary stability between collarless and collared versions of the same femoral stem. Specifically, we tested differences in subsidence and micromotion. Methods Collarless and coll ...

A statistical shape model to predict the premorbid glenoid cavity

Alexandre Terrier, Philippe Büchler, Alain Farron, Steve Michel Berger, Daniel Abler

Background: This study proposes a method for inferring the premorbid glenoid shape and orientation of scapulae affected by glenohumeral osteoarthritis (OA) to inform restorative surgery. ...

Dual mobility cups provide biomechanical advantages in situations at risk for dislocation: a finite element analysis

Alexandre Terrier, Valérie Parvex, Maïka Réane Guillemin, Adeliya Latypova

Purpose Constrained devices, standard implants with large heads, and dual mobility systems have become popular options to manage instability after total hip arthroplasty (THA). Clinical results with these options have shown variable success rates and signi ...

Importance of trabecular anisotropy in finite element predictions of patellar strain after Total Knee Arthroplasty

Dominique Pioletti, Alexandre Terrier, Adeliya Latypova

Patellar fracture and anterior knee pain remain major complications after Total Knee Arthroplasty (TKA). Patient-specific finite element (FE) models should help improve understanding of these complications through estimation of joint and bone mechanics. Ho ...

Effect of changes of femoral offset on abductor and joint reaction forces in total hip arthroplasty

Alexandre Terrier, Maïka Réane Guillemin, Adeliya Latypova, Hannes Andreas Rüdiger

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 ...
