Analogous to this case is that of Lawrence, who details the instance of a woman who had been delivered five times of dead children; she had a very narrow pelvis and labor was always induced at the eighth month to assure delivery.

In her sixth pregnancy she had miscalculated her time, and, in consequence, her uterus ruptured in an unexpected parturition, but she recovered and had several subsequent pregnancies.
Occasionally there is a spontaneous rupture of the vagina during the process of parturition, the uterus remaining intact.

Wiltshire reports such a case in a woman who had a most prominent sacrum; the laceration was transverse and quite extensive, but the woman made a good recovery.
Schauta pictures an exostosis on the promontory of the sacrum.
Blenkinsop cites an instance in which the labor was neither protracted nor abnormally severe, yet the rupture of the vagina took place with the escape of the child into the abdomen of the mother, and was from thence extracted by Cesarean section.

A peculiarity of this case was the easy expulsion from the uterus, no instrumental or other manual interference being attempted and the uterus remaining perfectly intact.
In some cases there is extensive sloughing of the genitals after parturition with recovery far beyond expectation.

Gooch mentions a case in which the whole vagina sloughed, yet to his surprise the patient recovered.
