Results of a study of the femoral bicondylar angle in adult and juvenile humans and great apes are presented. These results raise the question of whether or not the measurement reference of this angle is valid. This is because humans and great apes have a very different growth process of the distal epiphyseal suture of the femur during the period between birth and adulthood. The approximately 3 million years old juvenile femoral diaphyses attributed to Australopithecus afarensis (AL 333-110 and AL 333-111) were also studied. These specimens show an insertion of the diaphysis into the epiphysis of the simplified type typical of modern humans. This region is more convoluted in nonhuman anthropoids. Pelvifemoral interrelations are investigated through both longitudinal and cross-sectional radiographic studies of 23 human children. Growth changes in bicondylar and collo-diaphyseal angles, total femoral and femoral neck lengths, and interacetabular distance are correlated with age and to each other. These results are used to demonstrate the distinctive features of the Australopithecus afarensis fossil, AL 288-1.
本文展示了一项针对成年和幼年人类以及大猩猩股骨双髁角的研究结果。这些结果引发了关于该角度测量参考是否有效的问题。这是因为人类和大猩猩在出生至成年期间,股骨远端骨骺缝线的生长过程存在很大差异。对约300万年前归因于阿法南方古猿(AL 333 - 110和AL 333 - 111)的幼年股骨干也进行了研究。这些标本显示骨干插入骨骺的方式为现代人类典型的简化类型。在非人类类人猿中,该区域更为复杂。通过对23名人类儿童进行纵向和横断面放射学研究,对骨盆与股骨的相互关系进行了调查。双髁角和颈干角、股骨总长度和股骨颈长度以及髋臼间距离的生长变化与年龄以及彼此之间存在相关性。这些结果用于展示阿法南方古猿化石AL 288 - 1的独特特征。
