Femoral Torsion: Impact of Femur Position on CT and Stereoradiography Measurements

American Journal of Roentgenology, 2017
The purpose of this study is to evaluate stereoradiographic measurements of femoral torsion with different femoral positions, in comparison with CT measurements, with use of the current standard axial-slice technique. We hypothesize that CT measurements vary with femoral spatial positioning because of the resulting projection onto the CT plane, whereas

Torsional vibration induced with the position dependent impacts

2022
The important issue of the torsional vibration induced with impacts which depend on position is investigated in terms of nonlinearities that can still be handled with modal superposition. The considered models involve non-classical damping and rigid body modes.

Nonlinear oscillations of the torsion oscillator with impact masses

1997
This paper deals with nonlinear oscillations of the torsion oscillator with reciprocal rigidly connected impact masses. It is assumed that two impulses occur at one interval of the disturbing torsion moment. The asymptotic Krilow-Bogolyubov-Mitropolyskiy method is applied, along with the stereomechanical impact theory for the inclusion of impact ...
