Any condition which pre-vents the presenting part ofthe foetus from accurately fit-ting the pelvic brim is condu-cive to prolapse of the we find it most com-monly in contracted pelves andwith abnormal important causes are anexcessive amount of liquoramnii and early rupture of themembranes, especially if thepatient be in an upright posi-tion ; also an unusually longcord and low attachments ofthe placenta.
