A, spina bifida should be able to be found in utero. The ultrasounds on the baby would be able to see if there's an opening on the spine. However, tethered cord isn't found through ultrasound while you are pregnant. It would have to be found after the baby is born. I'll call you while I'm on my way home today and talk to you more.
Re: spina bifida? what do you know about it?
