The ultrasound femur length as a predictor of fetal length.


A linear relationship between the ultrasound fetal femur length and the crown-heel length of the fetus is described. The formula for calculating the fetal length in centimeters was found to be 6.18 + 0.59 x femur length in millimeters. The value and potential uses of the calculated length of the fetus are discussed.
