Many women in resource-poor settings lack access to reliable gestational age assessment because they do not know their last menstrual period; there is no ultrasound (US) and methods of newborn gestational age dating are not practised by birth attendants. A bespoke multiple-measures model was developed to predict the expected date of delivery determined by US. The results are compared with both ...

The corona mortis is defined as the vascular connection between the obturator and external iliac systems [1]. Usually, the obturator vessels originate from the internal iliac vessels and traverse the lateral pelvic wall along with the obturator nerve. There are marked variations of these vessels in relation to their origin, course and the distance from the pubic symphysis [2]. The name “corona ...

Parity indicators in human skeletal material are highly desirable yet elusive. In this study, the relationships of dorsal pits and pubic tubercle elongation to parity are investigated in a sample of 148 modern female sets of pubic bones with associated birth information. The elongation of the pubic tubercle shows no significant correlation with number of births, but instead is associated with t...

We studied changes in the width of the symphysis pubis in 32 women examined serially by ultrasound during labor. Measurements were made at the superior border of the symphysis and at its narrowest breadth in the latent phase, the active phase, and the second stage of labor. There was a significant increase in the width of the symphysis between the first and second stages of labor at both measur...

OBJECTIVE To present a new gestational-age-specific percentile curve for symphysis-fundus (SF) height and to determine the effects of maternal and fetal covariates. DESIGN A population-based register study. SETTING Antenatal clinics in Västra Götaland County, Sweden, between 2005 and 2010. POPULATION A total of 42 018 women with ultrasound-dated singleton pregnancies who delivered at Sahl...

OBJECTIVE  To create international symphysis-fundal height standards derived from pregnancies of healthy women with good maternal and perinatal outcomes. DESIGN  Prospective longitudinal observational study. SETTING  Eight geographically diverse urban regions in Brazil, China, India, Italy, Kenya, Oman, United Kingdom, and United States. PARTICIPANTS  Healthy, well nourished pregnant wome...

The contrasting effects of estrogen upon the pubic symphysis and long bones in mice is well known.'0 `` "' At the time new bone was forming in the long bones the number of reticular fibers increased in the marrow.' Because observations were made only after 30 days following implantation of estrone, it was not possible to determine whether these fibers were associated with the formation of new t...

This is a preliminary report on a method of pelvic osteotomy which we have found of value in the treatment of ectopia vesicae. The operation involves complete division of both iliac bones from crest to greater sciatic notch, together with the sacro-tuberous ligaments. A few days later fibrous tissue is removed from the pubic symphysis, the bladder is buried, and the divarication of the recti an...
