Detailed explanation-1: -The obstetric conjugate: Measured from the sacral promontory to the point bulging the most on the back of the symphysis pubis, located about 1 cm below its upper border. It measures 10.5 cm on average; it is the lesser anteroposterior diameter.
Detailed explanation-2: -Transverse diameters: Bituberous diameter = 11 cm : between the inner aspects of the ischial tuberosities. Bispinous diameter = 10.5 cm : between the tips of ischial spines.
Detailed explanation-3: -Obstetric diameters of the pelvic inlet-UpToDate. The three anteroposterior diameters of the pelvic inlet are the true conjugate (average diameter 11.0 cm), obstetric conjugate (average diameter 10.5 cm), and diagonal conjugate (average diameter 12.5 cm). Also shown is the anteroposterior diameter of the mid-pelvis.
Detailed explanation-4: -The transverse diameter, measured between the posterior parts of the ischial tuberosities, is about 115 mm.
