Previous research has revealed that Japanese macaques (Macaca fuscata) trained in bipedal performance (Saru-mawashi) display a number of functionally related external skeletal changes, as well as some site-specific endostructural cortical and cancellous adaptations. Through radiography assisted by digital image processing, we investigated the trabecular pattern of the ilium and femoral neck of Sansuke, a macaque habitually bipedally trained for 8 years. A set of eight regions of interest on Sansuke were recorded for subtle structural characterization of the cancellous network and compared to a sample of 5 ilia and 23 femurs from 26 adult wild Japanese macaques. The measured variables include trabecular thickness, trabecular bone volume, and degree of anisotropy. As a whole, the site-specific textural characteristics of the cancellous network detected on the ilium and proximal femur of the bipedally trained macaque can be interpreted as functional adaptive responses to more compressive loads dissipated along the axis from the sacro-iliac to the coxo-femoral joint, and back.
