Question
What should I do if a fetus has abnormal proportions?
Answer
At 33+6 weeks, the fetal biparietal diameter is 8.5 centimeters, the femur length is 5.84 centimeters, and the humerus length is 5.24 centimeters. The estimated fetal weight is 1706+297 grams. Are these proportions normal? Urgent! Hello, a biparietal diameter of 4.3 centimeters is within the normal range for pregnancy week 18; the femur length of 1.8 centimeters is within the normal range for pregnancy week 15. The normal reference value for the biparietal diameter at week 17 of pregnancy is 3.97±0.44 centimeters, and the femur length is 2.52±0.44 centimeters. Your child’s leg length is indeed shorter than the normal value. It is not excluded that this could be due to a measurement error. Short legs are not necessarily caused by a lack of calcium. Most pregnant women encounter the issue of short legs during an ultrasound, and most of them are normal after birth. Leg length can be related to the angle of the ultrasound and the fetus’s position.
