Can a fetus with short humerus and femur not have abnormalities?

I am 34 weeks pregnant and 36 years old. At 26 weeks gestation my baby's femur measured normal, but humerus was 1 week and 2 days behind. At 34 weeks the humerus is 3 weeks behind and femur is 1 week and 6 days. The BPD measured 34 weeks. Face profile was normal. No other markers were assessed. An amniocentesis was offered, but we declined because I will be having a C-Section in 5 weeks and it takes 2 weeks to get the results. Everything I've found on the internet screams downs syndrome and I am a nervous wreck. My husband is about 5'10 and I'm almost 5'6. My grandfather is about 5'0. Can this be a factor?
My question is: Can my baby still be born without problems with these measureents?

At my 32 week scan they told me he had short femur bone and his growth had slowed down  therefore they had me coming in to do fetal wellbeing scans and measuring scans nearly every 2 days at the hospital fir nearly a month, they then had me to go to another hospital a few weeks ago for them to do a scan as apparently their scanning equipment was better. When the doc came in all she was focussed on was telling me and my partner that it could be a sign of downes syndrome (i missed the 13wk scan for this and given my age 37 being a higher risk of it) I was beside myself. I was given 2 options the blood test and wait afew weeks for results or the needle in the stomach. I opted for the needle in the stomach as i wanted to know the results sooner as id been told theyd want to getthe baby out at 37 weeks because of the smal size (basically hes 2wks behind in growth) and 37wks wasnt far away.  I finally got the results over the phone bout the fish results for the main 3 chrimozones concerned 3 days later and came back al normal for downes downs (longest 3 days ever), then i got a report sent to me saying all the ither chromozome test came back normal aswell therefore putting my mind at ease that i was just having a short baby.  
I am having a csection nxt week, ill be 38wks and they were booked out for 37wks but have never been so scared in all my life knowing for little over a month that something could be wrong then be told i was high risk of him being downes. Now ill be just glad when hes finally here with nithing to worry about next week.
Small femur bones can just mean small baby, i was given all worrying scenarios throughout the process from 32wks due to the size and how far behind he was.
Like mine ive found that by the end of it all theres nothing to worry Bout and in some cases theyre told not the greatest of news but come out perfectly fine.
Go with ur gut or do what you feel is best and ask questions dont just go with what ever your told, do what u need to do to reassure yourself to put your mind at ease.
scans are usually a little bit out, dont worry too much bout how small the femur bone is if everything else is fine, ur just having a small baby.

On my 30 week ultrasound, my baby boy showed with a short femur and a high level of amniotic fluid.  Though at a follow-up visit a specialist did everything he could to assure me that the measurements were fine and with no other markers did not indicate any abnormalities, the feeling that my baby may have Downs or some other genetic abnormality never completely left me.  He was born perfectly healthy, without Downs or any other condition, 8 weeks later.  His legs actually do seem on the shorter side, but while my father his 6-feet tall, a couple generations back on my father's side the men in the family barely stood 5 feet tall.

I'm writing to just be one more voice that says DON'T WORRY and TRUST THE DOCTORS not the little voice in your head that is terrified by the SLIM chance that something is not as you thought.  I wasted many weeks checking message boards and checking and checking and crying and worrying.  Everything was just fine like the specialist said.  In fact, I had a very strange and admittedly illogical fear well in the back of my mind until he was several months old that somehow his abnormality was just escaping detection by his pediatrician, me, and everyone else.  I would routinely ask his pediatrician if anything looked "off" about him because that feeling just wouldn't leave me alone.  Hormones, you know?

Without other major markers or alarms, the short femur means NOTHING.  Relax and enjoy the rest of your pregnancies!  My baby boy is a cooing, laughing, happy, crawling 9-month old bundle of perfect health!

Hi I've just been for my 12 week scan and the scan has showen fluid inside the baby's head( the fluid is between the head and the skin,the skin should  be attached to the head but its not) and also the baby's limbs are disproportionately short..I have been told to terminate the pregnancy as this is just the start of underlying problem. But I don't want to so the next option is to do a genetics test and a fluid test..has anybody been through this,if you could please comment I am devastated.. The consultant has said this baby will be severely disabled..

I just came across your post and although it was a couple of months ago just wondered what has been happening since as my wife and I are in the same type of situation. Where along in her pregnancy is she now or have you had the baby and what was the outcome? I hope everything is or has turned out ok? Tom

My wife is 27 years old. At the latest scanning report says the FL & HL is 27 -29 weeks compared to rest of biometric parameters 35 - 38 weeks. and suggestive of short limb, suspicious club foot, polyhydramnios.

My wife is so panic.

Anyone can give the answer

Hi, my daughter turned out completely normal.  Her birth weight was low (~4lb7oz) but is a sharp and adorable, proportioned ~ 3 year old now.  Part of me regrets ever having the tests but I was so thankful to have the second opinion and finally get the images analyzed by the specialists down in LA.  No one is ever conclusive but hearing "it's probably not dwarfism" was a huge relief even if it came late into the pregnancy.  

We chose to have her induced about 2 weeks early suspecting the actual problem was an under-performing placenta (could be but they never could confirm either way).  

It's actually amazing how many doctors who have such confidence in their assessments are unaware of active research in this area.  As I was methodically documenting measurements at every chance (they wanted only visits every 2 weeks but we slipped in a few in the hospital when they were just checking fluid levels), he reaction was always something like  "well that's interesting, hmm".  By the end of this ordeal, I felt I was teaching him more about these things.  

Good luck!

Our baby boys femur measured in the 10th percentile. But he is perfectly normal he'll be 3 in November. His femur is still,a, little shorter but he's built like his father. My husband is 5'8 sorry legs like 29in inseam short lol a femur is shorter in comparison as well. But we never worried bc everything else logged normal and I am 4'10 and his grandfather was only 5'3 lol plus, all the over short ppl in the family lol. Try not to worry too much dear.

Hello, I wanted to post my story to try and prevent anyone else from going through the stress I did during my pregnancy. I used to search these boards daily trying to find reassurance to the point of unhealthy obsession and I really wish I had focussed on enjoying being pregnant and put my worries aside.

A private scan at 18 weeks and my 20 week NHS scan both showed my daughter's femur length to be behind the other measurements by up to a week, plotting between the 25th and 50th percentile lines on my baby's growth chart. After googling 'short femurs' I began to worry.

An ultrasound scan at 32 weeks then revealed I had a mild case of polyhydramnios, or excess amniotic fluid surrounding my baby, and that the femur length had now dropped down to the 9th percentile, between 2 and 3 weeks 'behind' the other measurements which were on or above the 50th percentile. After googling polyhydramnios my worry increased (it can indicate chromosome abnormalities) and despite the poly being attributed to a mild case of gestational diabetes I became absolutely convinced my baby had down syndrome, even though there were no other markers.

Ultrasound scans every two weeks (because of the diabetes) were also less than reassuring - the femur remained on the 9th percentile and at one point when I was 36 weeks the femur measured at 33 weeks while head circumference measured 38 weeks! When i mentioned my concerns to my consultant she dismissed my fears saying they didn't even use an isolated short femur as a soft marker but it did little to reassure me and I became obsessed to the point I was in tears most days, not eating, googling in the middle of the night, analysing my ultrasound scan pictures for 'signs' and ultimately putting strain on my relationship, my unborn baby and myself.

Even though I would love and want my baby no matter what, I was worried sick about our/her future and was battling between acceptance some days and, I'm ashamed to say,  outright fear of meeting her.

I went into labour at 40 weeks and even told the midwife delivering my baby that she might have down syndrome.

My daughter was born after a 9 hour labour and she did not have down syndrome. She was however, only 5lbs 16 so tiny all over!

Because of my worries throughout pregnancy I wasn't 'convinced' she was, for want of a better word, 'normal' and had her checked over by a senior peaditrician who thought I was mad (in hindsight I probably was!). When she asked me why I thought my baby might have down syndrome and I mentioned short femurs, she looked genuinely shocked and said they don't even consider that a marker in isolation, and said my daughter's legs didn't look short anyway!

Apart from the smallness my baby was/is perfect and healthy and is doing very well.

Sorry for the essay but I just could have done with something like this when I was pregnant. Please don't worry away your pregnancy like I did as I really think I made myself mentally and physically ill and put my baby at risk because of the worry (which ironically was probably the cause of her tiny size).

Also, when I was actually in labour I seemed to find a sense of peace with the situation, and I knew then that I would love her and do my best for her no matter what, and the fear of ds seemed to just disappear. She would be my baby regardless! There is also so much support out there and ds really isn't the end of the world.

I hope this helps you. Please, listen to the professionals and not dr google! Relax and enjoy the rest of your pregnancy!

Hi , im only 13 weeks and scared to death to loose my baby boy.... i had an ultrasound around 12 weeks that indicated 8 mm NT so they hurried and made me another apt in another town with dr who could run some test.. we ran an ultra sound there and they noticed the femurs were shorter.. and are now saying that my baby might have skeletal dysplasia
I did the CVS yesterday and waiting for more results.... they are basically telling me the baby wont survive with this  and would probably give birth to a still born :(,,, and trying to make me make a desicion for abortion.. they arent giving me a 100% they are sure this is what is wrong..

Hi Everyone,

Thank you for sharing your stories and offering comforting advice. We just found out at 17 weeks that our baby girls femur is short. We are scheduled for a Amnio in 2 weeks, AAAAAAAAHHH the wait! Is there any advice out there that would help during this difficult time because we are nervouse it might be Downs.
Thanks

Hi,
I just wanted to ask mommy2451 (or anyone else with a similar situation) more about how the doctor had handled the seemingly great outcome of your child.  It sounded like at birth the femurs was 5 weeks behind and the humerus was 6 weeks behind.  However, at 4 months of age, your baby 'caught up' or do you think the measurements throughout your pregnancy were actually wrong?

The reason I'm asking is because my wife and I also are now (at 24 weeks) hearing that our baby's femurs and humerus are behind around 3 weeks.  The doctor looked at the placenta blood flow and it looked fine.  We also had a CVS done early on and came up negative.  The doctor is now hinting there's a significant possibility of dwarfism since he cannot explain the bones being short; he seems about 2-3 children with dwarfism born each year.   He went even so far as to 'cross his fingers' at us during our last visit - really pouring fuel on our anxiety fire.  

I'm so glad to read all of these posts but am trying to understand whether
a) short femur, humerus (even 3 weeks) is not really a concern or
b) ultrasounds can just be inaccurate.  The prediction of being behind even 6 weeks can be entirely wrong.

I also did some more digging and found this site
http://www.geneticsofpregnancy.com/Encyclopedia/Achondroplasia_and_hypochondroplasia.aspx?pid=62&cid=106

which mentions
"As for diagnostic testing. Achondroplasia can be identified in the early weeks of pregnancy only by testing for the gene mutation in amniotic fluid cells. This test can be considered as soon as the combination of short femur and increased head circumference has been found, although in approximately 99% of cases the result is normal. "

I take this to mean that of all the cases where bones are short, diagnostic testing (of dwarfism) turns out to be 99% normal - resulting in normal babies.  If this is really true, I'm entirely turned off by the whole prenatal testing which, at least in our case, doesn't seem to be giving us this type of statistical, practical viewpoint on our situation.  

Sorry to vent but it sounds like everyone else seems to having similar stories.
Thanks

I have a friend who is pregnant with a high risk for a baby with downs syndrome and when she told me she said she hadn't even told her family yet and she didn't want to tell anyone as she didn't want to hear "oh that *****, I'm sorry"
Anyway she went on to say how grateful she would feel to be given a baby with downs syndrome,  she went on to tell me that they are such special people, they are so loving and they have such sweet spirits, and she would be so happy that she got to raise such a wonderful human being :-)
It will be a responsibility as there are things they can not do by themselves, but instead of being sad that you may have a child that's not "normal" be grateful that you get to be a mother to such a great and loving child.
When she told me I nearly cried as I had never heard anyone say anything as lovely as that, she just had such so much love, and it inspired me :-)

Not saying that your baby will have downs btw, just sharing a wonderful story of a wonderful friend :-)

I hope everything will be fine.

Even though I dont normally write in forums (just read), I needed to write this to give more hope and courage to suffering couples.

On  the 30th week of my wife's pregnancy we were told after an ultra sound that the baby's long bones (femur and humerus) are short (about 1.5 - 2 weeks behind).

24 hours ago my baby girl was born healthy with a length measurment 52 cm (20.47 inches).

Just keep your positive thoughts, Ultra Sounds cannot be perfect

I was in the same boat as you just earlier this year.
I was 34 pg with my 3rd At 20 weeks they noticed short femur and humerus.  I proceeded to worry and research for the next 20 weeks.  I was really worried because I would go in every 2 weeks for measuring ultrasounds and they were still growing, but so slow!  At 39 weeks humerus measured 33 weeks and the femurs at 34 weeks.

My husband is 5'8" andI am 5'6" (and one of the tallest in my family)
1 day overdue Nathan was born.  Healthy, normal,and the longest of my 3 babies!!!
He is now 4 months old and 16 lbs and 25 inches long.  They think the short measurments are just an indicator that he might not be 6'5" you know?

Please don`t worry. The ultrasound can lie sometimes.
I had the same experience with my little girl. When I was pregnant at every us scan the femur was shorter for 1 week compared with gestational age. Now my daughther is 2 month old and she looks perfect. It is genetic, my housband and I are short stature.
Also before delivery the doctor told me that she probably weights more than 7 pounds but she was less.
So, I`m sure you will have a very healthy baby.
