Feasibility of an alternative method to estimate glenohumeral joint center from videogrammetry measurements and CT/MRI of patients

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

Videogrammetry is commonly used to record upper limb motions. However, it cannot track the glenohumeral joint center (GH). GH is required to reconstruct upper limb motions. Therefore, it is often estimated by separately measuring scapular motions using sca ...

A statistical shape model to predict the premorbid glenoid cavity

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

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. ...

Effects of glenoid inclination and acromion index on humeral head translation and glenoid articular cartilage strain

Dominique Pioletti, Alexandre Terrier, Alain Farron, Christoph Anselm Engelhardt

Previous clinical studies have reported associations between glenoid inclination (GI), the acromion index (AI), and the critical shoulder angle (CSA) on the one hand and the occurrence of glenohumeral osteoarthritis and supraspinatus tendon tears on the ot ...

A semi-automated quantitative CT method for measuring rotator cuff muscle degeneration in shoulders with primary osteoarthritis

Alexandre Terrier, Alain Farron, Julien Ston, Antoine Dewarrat

Background: Rotator cuff muscle degeneration is an important parameter to consider when planning shoulder arthroplasty. Hypothesis: We hypothesized that rotator cuff muscle degeneration is correlated with scapulohumeral subluxation in patients planned for ...

Increasing upper limb training intensity in chronic stroke using embodied virtual reality: a pilot study

Olaf Blanke, José del Rocio Millán Ruiz, Andrea Serino, Gangadhar Garipelli, Thomas Schmidlin, Odile Hélène Chevalley

Background: Technology-mediated neurorehabilitation is suggested to enhance training intensity and therefore functional gains. Here, we used a novel virtual reality (VR) system for task-specific upper extremity training after stroke. The system offers inte ...

Effect 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 ...

Alignment of collagen fiber in knitted silk scaffold for functional massive rotator cuff repair

Dominique Pioletti, Weiliang Shen, Ting Zhu, Jiayun Huang

Rotator cuff tear is one of the most common types of shoulder injuries, often resulting in pain and physical debilitation. Allogeneic tendon-derived decellularized matrices do not have appropriate pore size and porosity to facilitate cell infiltration, whi ...

Effect of Patient Specific Parameters on Degenerative Shoulder Diseases

Christoph Anselm Engelhardt

Osteoarthritis and rotator cuff tears are two common and wide spread shoulder diseases leading to significant restrictions in the daily life of the affected. The pathogenesis is not fully understood yet. A chronic process triggered by multiple causes is as ...

Importance of a three-dimensional measure of humeral head subluxation in osteoarthritic shoulders

Alexandre Terrier, Alain Farron, Julien Ston

Hypothesis: During total shoulder arthroplasty (TSA), humeral head subluxation may be difficult to manage. Furthermore, there is a risk for postoperative recurrence of subluxation, affecting the outcome of TSA. An accurate evaluation of the subluxation is ...

Improving anterior deltoid activity in a musculoskeletal shoulder model – an analysis of the torque-feasible space at the sternoclavicular joint

Alexandre Terrier, Alain Farron, David Ingram, Christoph Anselm Engelhardt

Modelling the shoulder's musculature is challenging given its mechanical and geometric complexity. The use of the ideal fibre model to represent a muscle's line of action cannot always faithfully represent the mechanical effect of each muscle, leading to c ...

Comparison of an EMG-based and a stress-based method to predict shoulder muscle forces

Dominique Pioletti, Alexandre Terrier, Alain Farron, Philippe Müllhaupt, Valérie Hélène Emilie Malfroy Camine, Christoph Anselm Engelhardt, David Ingram

The estimation of muscle forces in musculoskeletal shoulder models is still controversial. Two different methods are widely used to solve the indeterminacy of the system: electromyography (EMG)-based methods and stress-based methods. The goal of this work ...

Evaluation of the muscular activity duration in shoulders with rotator cuff tear using inertial sensors and electromyography

Kamiar Aminian, Alain Farron, Cyntia Duc

Shoulder disorders, including rotator cuff tears, affect the shoulder function and result in adapted muscle activation. Although these adaptations have been studied in controlled conditions, free-living activities have not been investigated. Based on the k ...
