The pelvic inlet separates the pelvis into the greater/false pelvis (comprising the ala of the ilium above the arcuate line) and the lesser/true pelvis (Brown, 2010). The pelvic inlet is bounded by the sacral promontory, arcuate line, iliopubic eminence, pectineal line, pubic crest, and the pubic symphysis.
What is pelvis inlet?
The pelvic inlet or superior aperture of the pelvis is a planar surface which defines the boundary between the pelvic cavity and the abdominal cavity (or, according to some authors, between two parts of the pelvic cavity, called lesser pelvis and greater pelvis). It is a major target of measurements of pelvimetry.
What is normal pelvic inlet?
Pelvic inlet: The obstetrical conjugate is the distance between the sacral promontory and the inner pubic arch; it should measure 11.5 cm or more. The diagonal conjugate is the distance from the undersurface of the pubic arch to sacral promontory; it is 2 cm longer than the obstetrical conjugate.
