Summary
Obligate bipedalism is a unique feature of humans that results in the femoral head being loaded in a very specific manner in comparison to other primate taxa. The objective of this comparative analysis was to quantify the density variation of subchondral cortical bone in the proximal femur to look at how bipedalism loads the lower limbs differently than other forms of locomotor behavioral routines. High-resolution CT scans were collected from the femur of humans, chimpanzees, and orangutans. Subchondral articular bone was isolated from non-articular bone, and using a centroid probe analysis, continuous apparent density patterns were calculated and displayed using false color mapping. The results of the comparative analysis of the femoral head show that humans display very concentrated patterning within superior regions, orangutans show equal patterning within both superior and inferior regions, and chimpanzees show highly variant patterning of superior and inferior regions somewhere in between the previous taxa. This observation among all three taxa affirms the importance of body weight on the loading patterns of subchondral bone density within the superior portion of the femoral head for primates Subchondral bone provides a broad insight into the loading patterns that the proximal femur undergoes during varied locomotor behaviors, which can be further and more precisely examined in future studies that analyze trabecular architecture below the cortex and the influence of cortical thickness on cortical density.
