Macromechanics and polycaprolactone fiber organization drive macrophage polarization and regulate inflammatory activation of tendon in vitro and in vivo
Angelina D. Schoenenberger,Herbert Tempfer,Christine Lehner,Jasmin Egloff,Marita Mauracher,Anna Bird,Jonas Widmer,Katharina Maniura-Weber,Sandro F. Fucentese,Andreas Traweger,Unai Silvan,Jess G. Snedeker,Jess G. Snedeker +12 more
TL;DR: It is suggested that macrophages play a potentially important role as mechanosensory cells in tendon repair, and insight into how biological response might be therapeutically modulated by rational biomaterial designs that address the biomechanical niche of recruited cells is provided.

Biomechanical contribution of spinal structures to stability of the lumbar spine-novel biomechanical insights.
Jonas Widmer,Jonas Widmer,Frédéric Cornaz,Gita Scheibler,José Miguel Spirig,Jess G. Snedeker,Mazda Farshad +6 more
TL;DR: The small variability of contribution patterns are observed, suggesting distinct adaptation of the structures to one another, the biomechanical characteristics of one structure have to be put in context of the whole spinal segment.

Kinematics of the Spine Under Healthy and Degenerative Conditions: A Systematic Review
Jonas Widmer,Paolo Fornaciari,Marco Senteler,Marco Senteler,Tabitha Roth,Tabitha Roth,Jess G. Snedeker,Jess G. Snedeker,Mazda Farshad +8 more
TL;DR: A baseline definition of the spectrum of normal spinal kinematics is defined that allows a comparable definition of kinematic of the degenerative lumbar spine and stands at the precipice of technological breakthroughs that can power future large-scale studies.

Minimal mechanical load and tissue culture conditions preserve native cell phenotype and morphology in tendon-a novel ex vivo mouse explant model.
Stefania L. Wunderli,Stefania L. Wunderli,Jonas Widmer,Jonas Widmer,Niklaus Amrein,Niklaus Amrein,Jasper Foolen,Jasper Foolen,Unai Silvan,Unai Silvan,Olivier Leupin,Jess G. Snedeker,Jess G. Snedeker +12 more
TL;DR: It is concluded that onset of tissue degeneration can be suppressed by low‐magnitude mechanical loading, and a minimal explant culture model featuring serum‐free medium with low mechanical loads seems to provide a useful foundation for further investigations.

Individualized prediction of pedicle screw fixation strength with a finite element model.
Jonas Widmer,Jonas Widmer,Marie-Rosa Fasser,Marie-Rosa Fasser,Eleonora Croci,Eleonora Croci,José Miguel Spirig,Jess G. Snedeker,Jess G. Snedeker,Mazda Farshad +9 more
TL;DR: An automated tool able to predict patient-specific screw fixation strength through finite element simulation was developed and Experimental and simulation pull-out strengths were highly correlated and the mean error was 20.25%.
