Dissipation Can Act as a Mechanobiological Signal in Cartilage Differentiation

Dominique Pioletti, Philippe Abdel Sayed, Arne Christian Vogel

Knee cartilage is a soft tissue having viscoelastic properties. Under cyclic loadings, viscoelastic materials dissipate mechanical loadings through heat generation. In knee cartilage, this heat might not be convected because of the tissue avascularity, res ...

Cartilage self-heating contributes to chondrogenic expression

Dominique Pioletti, Philippe Abdel Sayed, Arne Christian Vogel, Mohamadreza Nassajian Moghadam

Articular cartilage is a soft tissue showing inelastic properties. Under cyclic loading, inelastic materials may dissipate mechanical energy into heat. In knee cartilage, due to an intrinsic reduced heat convection related to its avascularity, a local temp ...

Damping properties of the nucleus pulposus

Dominique Pioletti, Arne Christian Vogel

Background: The nucleus pulposus is extremely deformable and it is not uncommon to observe strain amplitudes as large as 12.5% in physiological loading conditions. It has been shown that the nucleus pulposus contributes to the damping properties of the int ...

Prediction of spatio-temporal bone formation in scaffold by diffusion equation

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Alireza Roshan Ghias, Arne Christian Vogel

Developing a successful bone tissue engineering strategy entails translation of experimental findings to clinical needs. A major leap forward towards this goal is developing a quantitative tool to predict spatial and temporal bone formation in scaffold. We ...

Thermomechanical Hysteresis of Biological and Synthetic Hydrogels : Theory, Characterisation, and Development of a Novel Deformation Calorimeter

Arne Christian Vogel

The nucleus pulposus of the intervertebral disc is a gelatinous viscous hydrogel that has an essential role in the mechanics of the intervertebral disc joint. The viscoelastic properties of the nucleus pulposus significantly change in the course of time an ...

Effect of supraspinatus deficiency on humerus translation and glenohumeral contact force during abduction

Alexandre Terrier, Arne Christian Vogel, Alain Farron, Adrian Reist

BACKGROUND: Supraspinatus deficiency is the most frequent and important problem associated to rotator cuff pathologies. It reduces shoulder stability and can lead to osteoarthritis. The goal of this study was to develop a numerical model of the shoulder to ...

An algorithm to allow humerus translation in the indeterminate problem of shoulder abduction

Alexandre Terrier, Arne Christian Vogel, Alain Farron, Massimiliano Capezzali

The shoulder is one of the most complex joints of the human body, mainly because of its large range of motion, but also because of its active muscular stabilisation. Actually, the numerous stabilizing muscles and degrees of freedom yield indeterminate biom ...
