Three-dimensional evaluation of the transverse rotator cuff muscle's resultant force angle in relation to scapulohumeral subluxation and glenoid vault morphology in nonpathological shoulders
Alexandre Terrier, Alain Farron, Patrick Goetti, Matthieu Boubat
Background: Static posterior subluxation of the humeral head (SPSH) results in glenohumeral osteoarthritis. Treatment strategies for SPSH with or without resulting osteoarthritis remain challenging. There is growing interest in evaluating the rotator cuff ...
Mosby-Elsevier2024Association of the Posterior Acromion Extension with Glenoid Retroversion: A CT Study in Normal and Osteoarthritic Shoulders
Alexandre Terrier, Alain Farron, Patrick Goetti, Frédéric Vauclair
Posterior eccentric glenoid wear is associated with higher complication rates after shoulder arthroplasty. The recently reported association between the acromion shape and glenoid retroversion in both normal and osteoarthritic shoulders remains controversi ...
MDPI2022Age- and sex-specific normative values of bone mineral density in the adult glenoid
Dominique Pioletti, Alexandre Terrier, Alain Farron, Patrick Goetti, Frédéric Vauclair, Philippe Büchler
The objective of this study was to determine the normative bone mineral density (BMD) of cortical and trabecular bone regions in the adult glenoid and its dependence on the subject's age and sex. We analyzed computed tomography (CT) scans of 441 shoulders ...
WILEY2022Reduction 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). Hypothesis: This study aimed ...
ELSEVIER MASSON, CORP OFF2020Deep learning for the rapid automatic quantification and characterization of rotator cuff muscle degeneration from shoulder CT datasets
Alexandre Terrier, Alain Farron, Elham Taghizadeh, Philippe Büchler
Objectives This study aimed at developing a convolutional neural network (CNN) able to automatically quantify and characterize the level of degeneration of rotator cuff (RC) muscles from shoulder CT images including muscle atrophy and fatty infiltration. M ...
SPRINGER2020Feasibility of an alternative method to estimate glenohumeral joint center from videogrammetry measurements and CT/MRI of patients
Dominique Pioletti, Alexandre Terrier, Alain Farron, Philippe Müllhaupt, 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 ...
TAYLOR & FRANCIS LTD2020Glenoid 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 ...
2020Muscle co-contraction in an upper limb musculoskeletal model: EMG-assisted vs. standard load-sharing
Dominique Pioletti, Alexandre Terrier, Alain Farron, Philippe Müllhaupt, Ehsan Sarshari, Matteo Mancuso
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 ...
TAYLOR & FRANCIS LTD2020Automated CT bone segmentation using statistical shape modelling and local template matching
Alexandre Terrier, Alain Farron, Elham Taghizadeh, Philippe Büchler
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 ...
2019A Robotic Glenohumeral Simulator for Investigating Prosthetic Implant Subluxation
Kamiar Aminian, Alexandre Terrier, Alain Farron, Arash Arami, Matteo Mancuso
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. ...
