한국인태아골반의 중량

Abstract

The author has measured the weights of the pelves of 365 Korean fetuses ranging from the 4th to the 10th fetal months. computed their indices to body weight and determined their parameters. and the following conclusions have been drawn. 1). The weight of pelvis increases about 30 times during above ranging period. 2). The increasing rate of the weight of pelvis is lower than that of the body weight by 9th fetal month. but higher in 10th. 3). No difference is found in the weight of pelvis between both sexes. 4). No difference is found in the weight of hip bone between right and left sides.
