“…The influence of the SS and ST ligament on pelvis kinematics has been assessed, deploying a numerical model based on the FE method (Hammer, Scholze, et al, 2019 ; Ramezani et al, 2019 ). The model included fine detail fiber orientations of all pelvic ligaments and the hip joint (Pieroh et al, 2016 ; Schleifenbaum et al, 2016 ) and experimentally obtained load‐deformation data of the SS and ST from human cadavers (Hülse et al, 2009 ). The following hypotheses were addressed:…”

“…The first configuration “Stiffer state” considers the elastic properties of both ligaments to equal a value of 25 MPa, while the second configuration “Soft state” integrated the elastic properties of the ligaments based on previous authors' experiments considering the decreased mechanical stiffness of the SS and ST when compared to the sacroiliac ligaments (Böhme et al, 2011 ; Hülse et al, 2009 ). For the third configuration, “Transected state”, the complex of SS and ST was “transected” unilaterally as done in surgery, for example, for pudendal nerve release.…”

The alteration in mechanical properties of posterior pelvis ligaments may cause a biased pelvis deformation which, in turn, may contribute to hip and spine instability and malfunction. Here, the effect of different mechanical properties of ligaments on lumbopelvic deformation is analyzed via the finite element method. First, the improved finite element model was validated using experimental data from previous studies and then used to calculate the sensitivity of lumbopelvic deformation to changes in ligament mechanical properties, load magnitude, and unilateral ligament resection. The deformation of the lumbopelvic complex relative to a given load was predominant in the medial plane. The effect of unilateral resection on deformation appeared to be counterintuitive, suggesting that ligaments have the ability to redistribute load and that they play an important role in the mechanics of the lumbopelvic complex.
