Pelvic inlet area is associated with birth mode

Teresa Starrach et al.

Summary: This study examines the pelvic morphology of women who delivered vaginally, had cesarean sections, and were nulliparous using a novel 3D method. The aim is to identify differences in pelvic morphology among these groups.

Changes in plasticity of the pelvic girdle from infancy to late adulthood in Homo sapiens

Anna Maria Kubicka

Summary: Previous research on the effects of body mass on the pelvic girdle focused on adult females and males. This study investigated the association between body mass index (BMI) and pelvic shape during development and assessed the influence of the number of live births in females. The results showed a significant association between BMI and pelvic shape in young females and old males, but the association between the number of live births and pelvic shape in females was not significant. The study suggests that pelvic shape in adult females is less plastic compared to puberty, reflecting adaptations for supporting organs and fetus during pregnancy.

Three-dimensional volumetric muscle reconstruction of the Australopithecus afarensis pelvis and limb, with estimations of limb leverage

Ashleigh L. A. Wiseman

Summary: In order to understand the movement of an extinct species, we reconstructed the missing soft tissues of the skeleton and examined the segmental volume and muscular composition within the body. Using three-dimensional polygonal modeling, we reconstructed 36 muscles of the pelvis and lower limb based on imaging scan data and muscle scarring. Comparison with a modern human revealed similar limb functionality, suggesting comparable bipedal movement in the Australopithecus afarensis specimen AL 288-1. This polygonal muscle modeling approach shows potential for reconstructing soft tissues in hominins and providing information on muscle configuration and space filling.

Pelvic shape change in adult Japanese macaques and implications for childbirth at old age

Naoki Morimoto et al.

Summary: Human pelvic morphology shows sexual dimorphism that is most pronounced during peak fertility and becomes less marked during menopause. This study investigates pelvic development in Japanese macaques and finds that their pelvic morphology changes throughout adulthood, potentially adjusting to the higher obstetrical risks at advanced ages.

Bony birth-canal dimensions and obstetric constraints in hominoids

Natalie M. Laudicina et al.

Summary: Comparative studies have revealed obstetric differences between humans and other primates, indicating that the pelvic morphology and birth canal constraints in nonhuman apes are distinct from that of humans. These differences may be attributed to the adaptations required for bipedality.

Are parturition scars truly signs of birth? The estimation of parity in a well-documented modern sample

Lukas Waltenberger et al.

Summary: This study investigates the association of pelvic features with birth and other body variables in a sample of female individuals from New Mexico. The results suggest that dorsal pubic pitting is significantly associated with the number of births, while most pelvic features increase with age, independent of parity.

An integrative approach to examining the influences of size, phylogeny, and locomotion on os coxae shape variation in primates

Kristi L. Lewton

Summary: The study examines the relationship between three-dimensional os coxae shape and phylogeny, locomotor function, and size in primates. The findings show that phylogeny has a significant but less pronounced effect on shape compared to body size and locomotion. Among all primates, size and locomotion have significant effects on os coxae shape, even when accounting for phylogeny. However, among nonhuman primates, the relationship between locomotion and os coxae shape is not significant when phylogeny is considered.

Computerized restoration of a fossil cranium based on selective elimination of estimated taphonomic deformation

Hideki Amano et al.

Summary: This study presents a method to reconstruct the original antemortem appearance of deformed fossil craniums and successfully applies it to a cranium of Mesopithecus from the late Miocene of Greece. The method does not rely on symmetry assumptions and may contribute to improved accuracy, objectivity, and transparency in virtual reconstruction of deformed cranial fossils.

Effects of hybridization on pelvic morphology: A macaque model

Laura T. Buck et al.

Summary: The study found that the effect of admixture in Macaca mulatta is small and proportional to the relatively small morphological difference between the parent taxa. Sexual dimorphism appears to be the main determinant of pelvic shape in M. mulatta. Unlike the differences between Neanderthals and Homo sapiens, there is no difference in pelvic shape between Chinese and Indian M. mulatta.

Virtual reconstruction of the Kebara 2 Neanderthal pelvis

Mayowa T. Adegboyega et al.

Summary: The lack of well-preserved pelvises in the hominin fossil record has hindered robust analyses of shifts in critical biological processes throughout human evolution. The Kebara 2 pelvis remains one of the best preserved hominin pelvises, providing a rare opportunity to assess Neanderthal pelvic morphology and function. The new reconstructions show differences in pelvic morphology compared to previous measurements, highlighting specific features of the Kebara 2 pelvis.

Assessing the role of the pelvic canal in supporting the gut in humans

Jeanelle Uy et al.

Summary: This research examines how gut size influences the size and shape of the human pelvic canal. In males, larger gut sizes are associated with increased mediolateral canal dimensions at the inlet and midplane, while in females, larger gut sizes are associated with more medially-projecting ischial spines and a longer anteroposterior outlet. These findings suggest adaptations to create space for the gut and reduce the risk of pelvic floor disorders in females.

Sex differences in the pelvis did not evolve de novo in modern humans

Barbara Fischer et al.

Summary: Comparing pelvic sex differences across modern humans and chimpanzees reveals a similar pattern despite differences in magnitude of pelvis shape dimorphism, suggesting that this pattern did not evolve de novo in modern humans but was present in the last common ancestor of humans and chimpanzees.

Predicting pelvis geometry using a morphometric model with overall anthropometric variables

Erik Brynskog et al.

Summary: This study found that overall anthropometric variables can only explain 29% of the variance in pelvis geometry, with important shape variations not captured by these variables. This suggests that these unaccounted for shape variations could have significant implications for injury prediction in traffic safety analysis.

Peripartum Pubic Symphysis Diastasis-Practical Guidelines

Artur Stolarczyk et al.

Summary: The optimal development of a fetus depends on adaptive changes in a woman's body, particularly in the musculoskeletal system. Natural widening of the pubic symphysis and the sacroiliac joints occurs during childbirth and is usually reversible postpartum. Peripartum pubic symphysis separation is a rare condition with no standardized treatment approach.
