...Ru Tao; Michele J Grimm Childbirth or labor, as the final phase of a pregnancy, is a biomechanical process that delivers the fetus from the uterus. It mainly involves two important biological structures in the mother, the uterus—generating the pushing force on the fetus—and the pelvis (bony pelvis...

... to the stress distribution of a real physiological gait load. In the experimental part of this study, four fourth generation Sawbones pelvises of full composite type with model number 3415 [ 10 ] were tested. After a preliminary optical inspection of each artificial pelvis and comparing the four...

... are defined as bonded contacts replicating the physical nature of Sawbones pelvises. Thanks to muscles, ligaments, connecting joints, and soft tissues, the pelvis is wrapped and maintained in place in the musculoskeletal system of the human body. In the FE model, the pelvis is attached to the environment...

... with the biomechanical behavior of a cadaveric pelvis in double leg stance configuration under physiologic loading, and to utilize the validated model to compare open book versus intact strain patterns during gait. A cadaveric pelvis was experimentally tested under compressive loading in double leg stance, intact...

...Jiajing Yang; Gaiping Zhao; Haifei Xu; Fei Wang To present the ligament effects on sacroiliac joint (SIJ) stability and human pelvis biomechanical characteristics in two different positions by using three-dimensional (3D) finite element (FE) models of pelvis. Based on the computed tomography (CT...

.... The objective of this study was to study the effect of boundary condition on the pelvic biomechanics predictions. A 3D FE model of a pelvis using subject-specific estimates of intact bone structures, main ligaments and bone material anisotropy by computed tomography (CT) gray value was developed and validated...

.... In the augment case, the load path between the femoral head and the pelvis now passes through the augment as the superior rim of the acetabulum has been replaced. Contact-induced stress in the augment is similar in magnitude to that seen in the superior rim of the baseline case, although the stress pattern...

..., cortex involvement, and cement modulus affect pelvic bone stresses and strains under single-legged stance loading. Experiments were performed on a male cadaver pelvis under conditions of intact, periacetabular defect, and cement-filling with surface strains recorded at three strain gage locations...

...Andrew E. Anderson; Christopher L. Peters; Benjamin D. Tuttle; Jeffrey A. Weiss A better understanding of the three-dimensional mechanics of the pelvis, at the patient-specific level, may lead to improved treatment modalities. Although finite element (FE) models of the pelvis have been developed...
