This finding is typically identified on second trimester prenatal ultrasound, as femur measurements are part of the algorithm for pregnancy dating. While often there are no other abnormalities, the following should be included in the care plan:

Should I be worry about short femur length pregnancy?

Conclusions: Isolated short femur length on second-trimester sonography is associated with a greater than 3-fold increased risk of fetal growth restriction and an increased risk of preterm birth. Serial growth assessment may be warranted in these cases.

What causes short femur in fetus?

In most cases, researchers suspect congenital short femur is caused by a disruption during early prenatal development, which can be caused randomly, or as a result of an outside force such as an infection or trauma.

What does short femur length mean in third trimester?

During the third trimester a very short femur may indicate a bone dysplasia and the work-up should be the same as in the second trimester. A short femur may correspond to dwarfism of late development, a growth-retarded foetus or constitutional shortness.

Do Down syndrome babies have short femurs?

Abstract. Short stature is a well-recognized component of Down syndrome. The femur lengths of affected fetuses have been observed to be shorter than normal, with a ratio of actual to expected femur length of less than 0.91 indicating a high risk of trisomy.

What does a short femur length on ultrasound mean?

Measured from the blunt end of the bone to the shaft, the femur length is generally measured in millimeters. A short femur length finding on ultrasound may indicate the need for further testing to rule out certain conditions.

What happens if your femur length is too short?

Some studies have raised concerns about the sufficiency of the placenta to provide an adequate nutritional environment for fetuses with short femur lengths. Because of that, short femur length is linked to adverse pregnancy outcomes such as fetuses that are small for gestational age, babies born with low birth weight, and preterm birth. 4

What is short femur diaphysis length?

Short FL was defined as a femur diaphysis length below the 5 th percentile of the chosen reference curve, corresponding to the mean minus 1.645 SD. Information about prenatally and postnatally detected chromosomal abnormalities was obtained from the Danish Cytogenetic Central Register (DCCR).

What did the Tech say about the femur measurement?

The tech said everything looked normal but said “the femur is on the shorter side, so that might explain why the fundal measurement is lower”. She didn’t elaborate but just said baby could be on the shorter side, and ended with “all good!”. Overall baby measured 49th percentile, 6 lbs 7 oz I think.
