Good question! I looked into cords more than shoulders this go, and learned some nifty stuff. Completely fascinating what the placenta and cord can do. Guess shoulders should be my next interest, since the latest arrival had to be helped out - Ty's broad sexy shoulders seem genetic.
I do know that cracked infant collar bones and broken mother's tailbone do occur from this sort of thing, so while painful and hard to think about… it's a way.
Yes, they also say that sometimes collarbones and tailbones have to be broken to solve shoulder dystocia. I however have doubts as whether a mother can do that through sheer pushing force alone.
If that position doesn't work, the other way to fix it is to move down onto all-fours. In most of the birth videos I've seen that had shoulder dystocia they used this position first, and it worked. I think its Ina May Gaskin maneuver?
Another thing is to apply pressure on mother's pubic bone. I'm not sure how well this would work if you're alone though? I'm sure there's other videos where you can see it done but the one that comes to mind is this one: hxxps://www.youtube.com/watch?v=3LO1KzkRwmU
Also, they can usually just help the shoulders turn manually, or reach in and help an arm be born (if the arm position is the problem). But I don't know if these would be viable options if you were delivering alone.
Breaking the baby's collarbone like you mentioned would only be used as an absolute last resort option… Because that could cause nerve damage or paralysis or other issues later in life.
I'm sure there are other things you could do, but that's all I can think of right now! Please share this story when you're finished with it though, because it sounds hot.
My ideas sound hot, but I wish my writing was as good as my ideas. I should've paid more attention in english classes lol.
Another option. Sort of. That site is full of fantastic information (and links to birth stories) but a pain to navigate mobile. A couple of positions and exercises helped me out with the intense discomfort of the last few weeks.
