Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Correlations between cancellous bone architecture and its dynamic behaviour [PDF]
Previous studies showed that in vivo evaluation of the fracture risk of cancellous bone can be assessed by identifying the relationships between its microarchitecture description extracted from clinical imaging and its mechanical properties.

【Abstract】With rapid advancement in surgical techniques and improvement in implant materials, rate of internal fixation for pubic symphyseal disruption in rotationally and vertically unstable pelvic ring injuries has increased. Among various modes of

Jordan et al. test two titanium cable-clamp implants to reduce pubic symphyseal gapping. Using synthetic bone models and cadaver specimens they show that their implants provide stabilities equivalent to that of a traditional symphyseal plate fixation.

Posttraumatic Osteolysis of the Pubic Bone Simulating Malignancy [PDF]
Posttraumatic osteolysis (PO) of the os pubis is a diagnostic entity characterized at radiography by rapidly progressing destructive changes in fractures of the pubic body or rami. Fourteen patients with PO are here reported of whom in 8 the radiographic course of the condition was followed. They were all post-menopausal women and 7 were predisposed to

The mechanism of labor in nonhuman primates: A look inside
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

A biomechanics study on ligamentous injury in anterior-posterior compression type II pelvic injury
Background Anterior-posterior compression (APC) type II pelvis fracture is caused by the destruction of pelvic ligaments. This study aims to explore ligaments injury in APC type II pelvic injury.

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.
