胎儿股骨增长模式的研究

Study of femur growth pattern in human fetuses

作者测量了44例3至9月份佳木斯地区胎儿的股骨最大长、中部最大径、中部最小径、骨化段长和重量。结果表明:五项测量指标侧别和性别差异均无显著意义,各项指标的增长与坐高的增长呈平行趋势,增长幅度有差异。最大长、骨化段长和重量增长幅度大,而中部最大径和最小径增长幅度则较小。建立了推算坐高的逐步回归方程。本文结果对于研究胎儿股骨的生长是非常重要的。

Forty four femurs of Jiamusi fetuses(ranging from 3 to 9 months pcsteonception)were studied by the measurement method to define the pattern of femur growth.The femur measure- ments analysed were their maximum length(X1),midshaft maximum breadth(X2),midshaft minimum breadth(X3),ossified shaft length(X4)and weight(X5).The results showed that there was no statistical significance in side and sex difference of these measurements.The increase in these measurements and sitting height showed a parallel trend with different growth rate and the X1,X4 and X5 showed higher growth than X2 and X3.The stepwise regression equation were made for estimating the sitting height.Thus,these findings are important to the knowledge of human femur growth.
