Question #474

Considering the pelvic inlet, which of the following statements is correct?

The pelvic inlet marks the superior margin of the true pelvis. Above this is the false pelvis or greater pelvis.

The bony edge of the inlet is marked by the pelvic brim and consists of:

  • Sacral promontory
  • Arcuate line of ilium
  • Iliopectineal line
  • Pubic crest

The inlet is angled at up to 50 degrees from the horizontal. In contrast, the pelvic outlet is normally at 15 degrees.

The anteroposterior diameter is measured from the pubic symphysis to the sacral promontory and is greater in females.
