A RARE CASE OF CHANGE OF POSITION OF THE PRESENTED HEAD IN THE PELVIC CAVITY DURING LABOR

In the past 1892, several interesting cases were observed in the maternity ward of the Kharkov obstetric clinic. One of these cases I had to carry out, with the permission of the deeply respected professor N.F. Tolochinov, I find it worthwhile to describe, since it presents some, rare and little known, features regarding the mechanism of childbirth. In this case, there was the so-called posterooccipital presentation, in which there was a change in the position of the head, which had already descended into the pelvic cavity.
