- Abstract
The paper aims to discover the development rule of fetal parital bone. One hundred and eighty parietal bones of 5-38th weeks old were observed and measured. With the Noback’s method every fetus was made transparent and then dyed dark red by the Alizarin red. The measured data are added to differential and integral calculus formula to calculate parietal ossification length and make correlated regression analysis. The results show that the time of ossification of different parts of fetal parietal bones are between the 9th and the 38th week. The parietal sagittal ossification length is 85.12 1.07mm and the coronary ossification length is 82.62 1.24mm. from the 37th to the 38th week, parietal coronary ossification bending appears. from the 13rd to the 14th week with the bending height being 3.74 0.47, and sagittal ossification bending occurs from the 17th to the18th week with the bending height being 1.60 0.45. Correlation analysis shows that parietal sagittal ossification length and coronary ossification length have highly positive correlation with gestational age respectively r=0.9926, 0.9869 P 0.01 . Two regression equations are established, and parietal ossification diameter length can be estimated. It can be concluded that fetal parietal sagittal ossification length is greater than coronary ossification length. Coronary ossification bending appears earlier than sagittal ossification bending but sagittal bending height is greater than coronary bending height.
