Hello, I would be happy to help you with your question.
I am so sorry about this news. This is a serious problem and you need someone to explain these results to you better! By 28 weeks, the limbs
should be completely developed. In answer to your question, no the baby will not be able to develop the arms and legs. The findings that they described to you can be incredibly varied, so before assuming the worst, it sounds like you need to ask for a visit with someone who can explain these results to you better. Also, you need to ask if there were any other findings of concern. Again, I am so sorry about this news.
