“…Sonography has again been applied to measure the approximate cephalic radius of the metatarsals. The mean intersubject values are well in accordance with the range of values measured by Largey and colleagues (Largey et al, 2007) on a larger set of bones using CT scanning.…”

In the present study we have estimated the temporal elongation of the plantar aponeurosis (PA) during normal walking using a subject-specific multi-segment rigid-body model of the foot. As previous studies have suggested that muscular forces at the ankle can pre-load the PA prior to heel-strike, the main purpose of the current study was to test, through modelling, whether there is any tension present in the PA during early stance phase. Reflective markers were attached to bony landmarks to track the kinematics of the calcaneus, metatarsus and toes during barefoot walking. Ultrasonography measurements were performed on three subjects to determine both the location of the origin of the PA on the plantar aspect of the calcaneus, and the radii of the metatarsal heads. Starting with the foot in a neutral, unloaded position, inverse kinematics allowed calculation of the tension in the five slips of the PA during the whole duration of the stance phase. The results show that the PA experienced tension significantly above rest during early stance phase in all subjects (P<0.01), thus providing support for the PA-preloading hypothesis. The amount of preloading and the maximum elongation of the slips of the PA decreased from medial to lateral. The mean maximum tension exerted by the PA was 1.5 BW (body weight) over the three subjects.

“…Our method for determining torsion is similar to the approach used by Largey et al (2007), although their process for determining the articular axes differed from that used here. Largey et al (2007) determined the proximal and distal axes based on the crosssectional properties of the metatarsal shaft, whereas here these axes were determined as the major axes of the articular surfaces.…”

“…Largey et al (2007) determined the proximal and distal axes based on the crosssectional properties of the metatarsal shaft, whereas here these axes were determined as the major axes of the articular surfaces. In keeping with previous studies (Largey et al, 2007), medial rotation of the metatarsal heads (i.e., pronation) was considered positive torsion, while lateral rotation (i.e., supination) was considered negative torsion. A small intraobserver repeatability study was done to assess the reliability of our method.…”

The Dmanisi hominins inhabited a northern temperate habitat in the southern Caucasus, approximately 1.8 million years ago. This is the oldest population of hominins known outside of Africa. Understanding the set of anatomical and behavioral traits that equipped this population to exploit their seasonal habitat successfully may shed light on the selection pressures shaping early members of the genus Homo and the ecological strategies that permitted the expansion of their range outside of the African subtropics. The abundant stone tools at the site, as well as taphonomic evidence for butchery, suggest that the Dmanisi hominins were active hunters or scavengers. In this study, we examine the locomotor mechanics of the Dmanisi hind limb to test the hypothesis that the inclusion of meat in the diet is associated with an increase in walking and running economy and endurance. Using comparative data from modern humans, chimpanzees, and gorillas, as well as other fossil hominins, we show that the Dmanisi hind limb was functionally similar to modern humans, with a longitudinal plantar arch, increased limb length, and human-like ankle morphology. Other aspects of the foot, specifically metatarsal morphology and tibial torsion, are less derived and similar to earlier hominins. These results are consistent with hypotheses linking hunting and scavenging to improved walking and running performance in early Homo. Primitive retentions in the Dmanisi foot suggest that locomotor evolution continued through the early Pleistocene.

“…In humans, there is very little torsion in the first metatarsal, with progressively more torsion from the second to fifth metatarsals ( Fig. 9b) (Elftman and Manter, 1935a;Aiello and Dean, 1990;Largey et al, 2007). The opposite occurs in the apes where there is progressively less torsion from the second to fifth metatarsal, allowing the forefoot to lie in an inverted position (Morton, 1922;Lewis, 1980;Aiello and Dean, 1990).…”

Earliest complete hominin fifth metatarsal—Implications for the evolution of the lateral column of the foot

StW 114/115, from Sterkfontein, South Africa, is the earliest complete hominin fifth metatarsal. Comparisons of StW 114/115 to modern humans, extant apes, and partial hominin metatarsals AL 333-13, AL 333-78, SKX 33380, OH 8, and KNM-ER 803f reveal a similar morphology in all six fossils consistent with habitual bipedality. Although StW 114/115 possesses some primitive characters, the proximal articular morphology and internal torsion of the head are very human-like, suggesting a stable lateral column and the likely presence of lateral longitudinal and transverse tarsal arches. We conclude that, at least in the lateral component of the foot of the StW 114/115 individual, the biomechanical pattern is very similar to that of modern humans. This, however, may not have been the case in the medial column of the foot, as a mosaic pattern of hominin foot evolution and function has been suggested. The results of this study may support the hypothesis of an increased calcaneo-cuboid stability having been an early evolutionary event in the history of terrestrial bipedalism.
