Spina bifida

So my husband injured his back a few months ago working out. The pain went away but then it came back and the pain would come and go. He went to the doctors last week and they had him get an X-ray. The doctors office called him today and told him he has Spina bifida and some bad disks in his back and the are putting in a referral for him to see a orthopedic surgeon. Since my husband works a lot and he is not the type to ask questions he has put me in charge of all of that. Which is fine because at least I will make the appt and ask questions. The only problem I am having is what do i ask? I have started doing a little research today and it seems like there are different types. Does anyone have experience with this? If so what should I ask and are there any good resources I can look into until we see the doctor?
