I’m not sure about the relationship with femurs and downs. I think I saw it when I googled short femurs. Did you have any testing done first tri? I had an NT scan so I didn’t give much thought to the correlation of femurs and downs when I saw it online.

Yes i had nt scan, but i found some stories when short femurs were only marker during pregnancy so I'm still worried. Now less because they caught up:-)

My LO had a short femur marker at our 20 week scan and was told it could be anything from downs, dwarfism, skeletal dysplasia etc.... it turns out that doctor had no clue what he was talking about. A month later (and countless hours of stress and worry and research because the doctor REFUSED to answer any questions at the appointment) I went back to my regular OB for a checkup and mentioned what the doctor at the scan had said. They said it didn't seem right but sent me immediately to a high risk doctor for a detailed u/s. That doctor (who was amazing and patient and actually answered questions) said that a femur measurement in isolation really does not tell you anything at all. That there would be other markers as well such as a short humorous bone (from what i remember, he was speaking in terms of dwarfism and skeletal issues... i dont remember if he mentioned downs in this particular conversation). He said that the measurements in and of themselves are not wholly accurate or trustworthy...one technician might place the starting measurement in one spot and another just slightly off of that same starting spot...but that slight difference might make a big difference in where the baby is measuring...remember that we are talking about millimeters here.

Especially since your LO has caught up, if there are no other markers then I would try not to worry about it too much. 25% is awesome (i believe it's if you're measuring under 4% that they consider it to be "short" but i'm reaching back a couple years in my memory so that might be off). I'm sorry you are having to worry so much and I hope you can find some answers from your doctor soon to help alleviate some of the anxiety.

As a sidenote, my son had caught up after that month (babies go through different states of growth spurts). He was born around the 50th percentile for length and is now around 86% or so at age 4.

thanks. My doctor isn't worried. I read too much in google, I don't know why, it only scares me. My baby's femur was ok on anatomy scan, but short on 22, 24, 26 and 28 week scan ( i have them very often not because of femur lenght) and finally on 30week scan they has caught up and were on 25%. I hope they will still grow. She is overally not very big ad her head, belly and femur are now all around 20-30 %.

My sons femur length was five weeks behind his tummy measurement and two weeks behind his head measurement by the time he was born, heís fine just s little shorter than average but looked perfectly proportioned when he was born. If there was an issue other markers would have been picked up as well. Itís hard but try not too worry.
