I don't but a good friend of mine does... she has a lil girl and had a long labor but turned out well. She was in labor for 3 days trying to go vaginal but it didn't end up happening. Also she had to be put out for her c-section because the scoliosis made the epidural not take (I guess they tried several times and just wouldn't work because of where her spine was fused)
In the end though, healthy baby and healthy mama!
I had the herrington rods put in my back when I was about 12 years old - I had an S-curve and they only corrected the top curve, so I still have a slight curve in my lower back. I had my DD in Aug of 2006 and did it completely drug free - I could have had an epidural, the anesthesiologist wanted an x-ray of my back (which I still has from when I was 12) but I decided on a natural birth to begin with.
I didn't find my scoliosis or herrington rods to be a factor in my pregnancy or L&D in any way whatsoever. In fact, I think it may have helped if that makes sense, the rods helped support my back during pregnancy and I never had any back pain. Not sure that would have been the case without rods.
