Abstract:
The femurs of 98 Chinese fetuses were observed and measured with radiographic method. A series data of femur-length and -width of different fetal-age groups was obtained. Calculated femur index (width/length?100)showed that the proportion between the femural length and the femural width remained considerably constant dur- ing the development of the fetus. The positive correlation between the length of the femur and the C-R length was revealed by statistical analysis; a regression equation was obtained. The authors suggest that it is possible to take the femural length as a criterion parameter to estimate the fetal age.
