In brief: Femur length
Ultrasound imaging of the fetus can determine femur length with great accuracy.
The normal relationship between the bones of the lower leg and femur is 1:1. If the femurs are short, either a constitutionally normally small fetus (frequently offspring of short parents), intrauterine growth restriction (iugr) or a skeletal dysplasia may exist. Normal short fetuses exhibit appropriate interval growth.

In brief: If you mean length
of the femur on a fetal ultrasound, ask your OB about its significance & if there are other findings that suggest dwarfism. You may wish to consult a Fetal-Maternal Medicine specialist.
Dwarfism can be diagnosed on FUS from 16-32 weeks, depending on the type. Anxiety during pregnancy has its own risks. Don't add to your concerns about advanced maternal & paternal age needlessly; seek an answer.
