頭蓋最大長と骨盤計測値の間の有意な関連--短頭化現象問題の解決に向けて Significant Associations between Cranial Length and Pelvic Measurements: Toward the Solution of the Brachycephalization Problem
Search this Article
As a step toward elucidating the causes of brachycephalization, correlations between neurocranial and pelvic measurements were examined using principal component analysis and Kaiser's normal varimax rotation methods. The results show that, while cranial breadth has no systematic relation with any pelvic measurements, cranial length is significantly associated with the height of the innominate, maximum pelvic breadth, and anterior upper spinal breadth in both sexes. These findings support the previous suggestion from the analyses of the sacrum that the form of the maternal pelvic inlet has been and is still one of the most important determinants for the neurocranial form, and suggest the possibility that one of the causes for brachycephalization may be a secular change in the shape of the pelvis.
