The line between the closest bone points of the ischial spines: 9.5 to 11.5 cm. [6] Pelvic outlet Sagittal pelvic outlet diameter Same, but may require minor side-to-side scrolling to visualize both end points. The closest bony points of the sacrococcygeal joint and the pubic bone next to the symphysis.
One of the biggest issues with the pelvic shape for childbirth is the Ischial spine. Since the ischial spines support the pelvic floor, if the spines are too far apart it can lead to a weakened pelvic floor muscles. This can cause issues as pregnancy progresses, such as difficulty carrying the fetus to full term.
The ischial spine is part of the posterior border of the body of the ischium bone of the pelvis. It is a thin and pointed triangular eminence, more or less elongated ...
When the presenting part is at the ischial spines the station is 0 (synonymous with engagement). If the presenting fetal part is above the spines, the distance is measured and described as minus stations, which range from −1 to −4 cm. If the presenting part is below the ischial spines, the distance is stated as plus stations ( +1 to +4 cm).
Bishop score, also Bishop's score or cervix score, is a pre-labor scoring system to assist in predicting whether induction of labor will be required. [1] It has also been used to assess the likelihood of spontaneous preterm delivery. [2]

In obstetrics, the presentation of a fetus about to be born specifies which anatomical part of the fetus is leading, that is, is closest to the pelvic inlet of the birth canal.
Between ischial tuberosities: 10–11 cm Interspinous distance: Between anterior superior iliac spines: 26 cm (female) Intercristal distance: Between furthest lateral points of iliac crest: 29 cm (female) External conjugate: Spinous process of fifth lumbar vertebra: Upper edge of symphysis ~20 cm Intertrochanteric distance: Between femurs: 31 cm
The body contains a prominent spine, which serves as the origin for the superior gemellus muscle. The indentation inferior to the spine is the lesser sciatic notch. Continuing down the posterior side, the ischial tuberosity is a thick, rough-surfaced prominence below the lesser sciatic notch. This is the portion that supports weight while ...
