Sorry to hear of your difficult birth, Donbean.
Was this your first baby?
With the mention of pre-eclampsia, I'm wondering if you were induced? One of the big things to watch out for with an induction is that the baby is in a perfect position for birth, otherwise you often get complications. You can't really disregard the value of those last few days and weeks of pregnancy and the Braxton Hicks contractions to line the baby up into an optimum position. Obviously, with pre-eclampsia, you had your health to worry about and it was in no way a "social" induction.
There isn't really anything "abnormal" about a frank breech - as Mary Cronk says, it's a variation on normal. The problem is is that you don't always know what kind of breech you have, and it's a big no-no to force out, by induction and acceleration, a footling or full (cross-legged) breech, because they don't usually fit through the birth canal (at least, safely). The last thing you want to do is force it against the mum's pelvis when it's got nowhere to go.
With a frank breech, the size of the baby's hips is about the same as its unmoulded head, so the chances of a good passage through the pelvis are the same as if the same baby were in a cephalic position.
I didn't have any problems with my frank breech. It was my fifth baby, so this may have made a difference. She came out in one contraction. The main difference in the labour is I had lots of extremely strong braxton-hicks in the days before - which I put down to getting the baby in the right position. In the labour itself, the ctx stayed fairly constant at about 3 mins apart (getting stronger in length and intensity, so we knew labour was progressing) - and they didn't overwhelm me. Consequently, it was a much longer labour - 6 hours instead of about 1-2 hours that I told my midwife to expect.
The only baby complication was a dislocated hip - which resolved itself within a couple of weeks. I don't think the birth itself made a difference to this - it was her sitting in the pelvis for several weeks that did it.
