Pregnant women in mid to late pregnancy need to undergo prenatal screening, mainly to check the physical condition of the fetus. After 4 months of pregnancy, as the various organs of the fetus gradually grow, women can undergo prenatal screening. The ultrasound examination results will display the length of the femur. So, what does fetal femur length refer to?
The femur is actually the thigh bone of the human body, which can be said to be the largest long bone in the human body. The femur length of a fetus refers to the length of its thighs. Measuring the femur length of a fetus is mainly used to predict its physical condition and biological indicators. Because the length of the femur represents the length of the lower limbs of the fetus, the height and weight of the fetus can be estimated.
Normally, women can measure the length of their femur at 13 weeks of pregnancy, and the longer the pregnancy, the longer the femur length will increase. If the length of the femur does not increase continuously or increases slowly, it should be noted that this may be due to delayed fetal development or insufficient nutrition in pregnant women, and nutritional supplementation is needed.
In general, femur length refers to the length of the fetal thigh bone, and detecting femur length can determine the development of the fetus. The length of the femur is related to the duration of pregnancy and genetics in pregnant women. Fetuses with taller parents will also have longer femurs, which means they will be taller.
