“…Upadhyay et al (1990) found no significant relationship between femoral anteversion and social class, order in family, parental age at birth, or birth presentation in children aged 2-15 years. Biomechanical forces are a primary contributing factor for the angle of anteversion during early growth and development (Tardieu, 2010;Bonneau et al, 2011). Nevertheless, generally the research supports a mechanical explanation for most of the variation in femoral torsion (LeVeau and Bernhardt, 1984;Tardieu, 2010;Bonneau et al, 2011), and Upadhyays and colleagues' (1990) results could be interpreted in this light.…”

Average femoral torsion has been reported to differ among populations, and several studies have observed a relatively high prevalence of femoral anteversion asymmetry in Native Americans, especially females. This study investigates sexual dimorphism and temporal trends in femoral torsional asymmetry among the Arikara from the seventeenth to the early nineteenth century. To establish if there are population differences, femoral torsion was first measured using a direct method on a diverse comparative sample of Native Americans from the Southwest, Midwest, and Great Plains as well as American Whites and Blacks. To examine temporal trends among the Arikara, femoral torsion was examined using the orientation of the maximum bending rigidity at subtrochanteric in 154 females and 164 males from three temporal variants of the Arikara Coalescent tradition. There is significant sexual dimorphism in femoral torsional directional and absolute asymmetry among most Native American samples, but not among American Whites and Blacks. Among the Arikara there is significant sexual dimorphism in femoral torsional asymmetry in all three temporal variants, and asymmetry in femoral torsional asymmetry increased significantly from the protohistoric to the early historic period among females. The increased femoral torsional asymmetry is likely associated with a common side-sitting posture observed in historic photographs of Great Plains females. Historic Arikara females may have habitually sat in this compulsory position for extended periods while conducting domestic chores. The dramatic change from the protohistoric to historic period suggests a cultural change in sitting posture among females that was widespread across the Northern Plains.

“…The fact that this ability has been maintained with increasing frequency requires the morphology of infants to allow bipedalism very early in life. This assumption does not exclude the potential influence of epigenetic factors [Tardieu, 2010]. Palaeo-anthropological studies on locomotor behaviour precursory to permanent bipedalism commonly regard hominoids as a potential model [Crompton et al, 2008[Crompton et al, , 2010.…”

Bipedal Behaviour in Olive Baboons: Infants versus Adults in a Captive Environment

The olive baboon is described as a committed quadrupedal primate. However, available data show that they actually use a variety of locomotor and postural modes. Bipedalism is observed occasionally but spontaneously in captivity and in the wild. As observed in other Catarrhini, immature baboons appear to be more bipedal than adults: this study aims to provide the necessary quantitative data to support this hypothesis, as none has been available so far. The locomotor and postural repertoire was quantified for two age classes: infants beginning to forage independently, and adults. Our results show that infants appear to have a wider repertoire than adults, and bipedal postures and locomotion in infants, although infrequent, appear to distinguish them clearly from adults. In captivity, behavioural context and morphology are the two main factors that could explain age-related positional differences, given a constant ecological context.

“…Aus der Anthropologie ist bekannt, dass der reife aufrechte Gang unter anderem mit einer zunehmenden, ökonomisch vorteilhaften Spurverschmälerung einherging. Im Laufe der Evolution rückte das Femur immer mehr zum Körperschwerelot, was zum einen dadurch möglich wurde, dass sich am Kniegelenk ein vordem nicht existenter Valguswinkel ausbildete [30,31]. Zudem entwickelte sich, relativ spät in der Entwicklungsgeschichte, Abb.…”

Zusammenfassung Hintergrund Apophysen und Apophysenfugen unterscheiden sich in ihrem Aufbau nicht wesentlich von Epiphysen und Epiphysenfugen, im Gegensatz zu diesen tragen sie jedoch nicht zum Längenwachstum der Extremitäten bei. Sie sind den jeweilig benachbarten Gelenken zugeordnet. Das apophysäre Wachstum bestimmt hierbei Hebellängen und beeinflusst die Gelenkform und -struktur. Der formative Reiz hierzu geht von Muskeln aus, die sehnig an den Apophysen inserieren oder diese überwölben. Apophyse des Trochanter major Die Apophyse des Trochanter major trägt wesentlich zur Kraftarmlänge des Hüftgelenkes bei. Ihre Wachstumsleistung bestimmt, ob sich der Schenkelhals valgisch oder varisch entwickelt, letztendlich hängt davon auch ab, ob eine Hüfte dezentriert oder nicht. Tibiaapophyse Die Tibiaapophyse gibt vor, wie stark das Tibiaplateau nach ventral oder dorsal geneigt ist (tibialer Slope) und beeinflusst somit die sagittale Stabilität des Kniegelenkes. Ist sie verletzt, dann entwickelt sich ein schwierig zu behandelndes Genu recurvatum. Calcaneusapophyse Die Calcaneusapophyse gibt die Länge und Stellung des Fersenbeines vor und trägt hiermit entscheidend zum Drehmoment des oberen Sprunggelenkes bei. Zusammenfassung Zusammenfassend lässt sich sagen, dass Apophysen als Stellschrauben angesehen werden können, welche das Wachstum, die Form und Struktur ihrer benachbarten Gelenke lenken.
