Patient specific numerical shoulder model based on medical imaging

The shoulder is often described as the most complex human joint because of its anatomy and the high number of muscles participating in arm movements. The anatomy and the development of muscles depend on personal characteristics and the style of living. The ...

Development of a 3D finite element muscle model

Christoph Anselm Engelhardt

Stability of the shoulder, more precisely the glenohumeral joint, can only be achieved in case of healthy and well coordinated muscular activity in the upper limb. Degenerative deseases like osteoarthritis, muscle deficiencies or injuries can lead to insta ...

Dynamical biomechanical model of the shoulder for muscle-force estimation

Alain Farron

A biomechanical model of the human shoulder complex is proposed for quasi-static and dynamic estimation of the muscle forces and joint reaction forces in the glenohumeral joint. The model bases itself on the Garner & Pandy model but adds a dynamic layer. T ...

Distribution of muscular forces in a numerical musculoskeletal model of the shoulder

Valérie Hélène Emilie Malfroy Camine

The shoulder is a complex joint with many muscles acting between the scapula and the humerus. Thus it is obvious that the mechanical system is indeterminate and an optimization method has to be used to find the muscular forces acting on the glenohumeral jo ...

Postoperative scapula fracture after reversed shoulder arthroplasty

Julien Ston

Reversed shoulder arthroplasty (RSA) is recommended in case of severe muscle deficiency, along with important joint wear. Although having a correct placement of the prosthesis after the operation and a recovery of the mobility, several cases of scapula fra ...

Simulation of postoperative scapula fractures after rTSA

Alice Ghislaine Concordel

Reverse total shoulder arthroplasty (rTSA) is recommended in case of severe muscle deficiency, along with important joint wear. Although having a correct placement of the prosthesis after the operation and a recovery of the mobility, several cases of scapu ...

Development of a test device for assessment of glenoid baseplates for reversed shoulder arthroplasty

Christoph Wenger

When rotator cuff deficiency is present with gleno-humeral osteoarthritis, the current treatment is a reverse total shoulder arthroplasty. The reverse shoulder prosthesis has inverted articular surfaces: a metallic ball (glenosphere) is fixed on the scapul ...

Importance 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 ...

Analysis of onset of dislocation nucleation during nanoindentation and nanoscratching of InP

Christophe Ballif, Johann Michler

Nanoindentation and nanoscratching of an indium phosphide (InP) semiconductor surface was investigated via contact mechanics. Plastic deformation in InP is known to be caused by the nucleation, propagation, and multiplication of dislocations. Using selecti ...

Objective evaluation of shoulder function using body-fixed sensors: a new way to detect early treatment failures?

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

Variable definitions of outcome (Constant score, Simple Shoulder Test [SST]) have been used to assess outcome after shoulder treatment, although none has been accepted as the universal standard. Physicians lack an objective method to reliably assess the ac ...
