A textbook of obstetrics . rapid in the rachitic pelvis,because of the shallow canal and the expanded outlet. Injuriesto the childs head and to the maternal tissues from pressure arecommon. In the former, a sharp indentation may be seen on thatportion of the skull pressed against the promontory in the effortsto secure engagement, the so-called spoon-shaped depression,with fracture ^\ the parietal bone. Localized necroses are notinfrequently seen in the maternal structures, where they have beennipped between the childs head and prominent portions of thepelvic bones—namely, in the cervical tissues over the promon-tory, or very rarely in the posterior vaginal vault, and in theanterior vaginal wall behind the symphysis and the ridge of thepubic bones. When the slough separates, openings may beestablished between the birth-canal and the peritoneal cavity,the bowel, the bladder, and a ureter.
