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 ...

A simulation framework for humeral head translations

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

Humeral head translations (HHT) play a crucial role in the glenohumeral (GH) joint function. The available shoulder musculoskeletal models developed based on inverse dynamics however fall short of predicting the HHT. This study aims at developing a simulat ...

Heightened clinical utility of smartphone versus body-worn inertial system for shoulder function B-B score

Kamiar Aminian, Alain Farron, Brigitte Jolles-Haeberli, Cyntia Duc

The B-B Score is a straightforward kinematic shoulder function score including only two movements (hand to the Back + lift hand as to change a Bulb) that demonstrated sound measurement properties for patients for various shoulder pathologies. However, the ...

A framework for forward-dynamics simulation of the human shoulder

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

A vast majority of the available biomechanical models of the human shoulder has been developed based on inverse dynamics, e.g. [1,2]. This imposes a number of limitations on their application. For instance, the glenohumeral joint is approximated as an idea ...

Modelling of the human shoulder as a parallel mechanism without constraints

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

The synthesis of shoulder kinematics, either for simulation in a model or imitation in a robot, is a challenging task because of the contact between shoulder blade and ribcage. As the shoulder moves, the shoulder blade glides over the ribcage. In kinematic ...

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 ...
