Brief Answer:
Chances of dwarfism are high; follow up is needed.
Detailed Answer:
Hi Ms. XXXXXXX
Thanks for writing to us.
I can understand your anxiety and the need of the hour.
Length of femur is important for the diagnosis of short long bones. Please furnish the figures if it was measured. Though familial short limbs and IUGR may be considered as causes of short long bones, there are more important skeletal deformities and dyplasias which are sometimes lethal that should be given first priority during the diagnosis. The spine, facial bones, skull, rib cage and thorax should be observed. Shape of the long bones should be observed. Follow up sonograms should be taken and other tests for detecting genetic defects may also be done.
Resistance in the uterine arteries may indicate a small for dates baby, impending PIH or the possibility of preterm delivery. Prophylactic therapy given before 20 weeks is beneficial.
Follow up is essential. Please contact a specialist in high risk pregnancy care to receive further attention.
Hope I have clarified your query. Please feel free to contact if you need further clarifications. I will be happy to help.
