In brief: Rare - bad!

Locked twins are monochorionic/monoamniotic twins that have locked heads so that the breech presenting one cannot be delivered because the cephalic second twin is holding it in utero by locking their jaws.
Extremely rare and potentially lethal, unless a cesarean section is promptly undertaken.
