Fetal femur length at 40 weeks is 69mm, is the leg short?

Patient's question:

No

Doctor's answer:

Hello, it's not like that, it's perfectly normal. Sometimes ultrasounds can also have errors. At 40 weeks of pregnancy, the average biparietal diameter (BPD) of the fetus is 90 ± 6.3 mm, the average abdominal circumference is 301.4 ± 20.17 mm, and the average femur length is 71 ± 5.2 mm.
