The 4 types of the female pelvis have been described (afterCaldwell and Moloy):

  • Gynecoid.
  • Android.
  • Platypelloid.
  • Anthropoid.

Types of the female pelvis (normal and its variations) and their features.

The table with ID 0 not exists.

Morphologically also the pelvis is split into thefollowing 4 types:

  • Mesatipellic (normal): When transverse diameter of the pelvic inlet is somewhat more in relation to the anteroposterior diameter.
  • Brachypellic (android type): When anteroposterior diameter of the pelvic inlet is marginally more in relation to the transverse diameter.
  • Platypellic: When transverse diameter of the pelvic inlet is considerably greater in relation to the anteroposterior diameter.
  • Dolichopellic: When anteroposterior diameter of the pelvic inlet is far more than the transverse diameter.

Clinical Significance

Fractures of The Pelvis

The pelvis is just like a ring. It’s quite powerful and generally takes an immediate violence of high velocity to fracture it. The feeble ssites of the ring are sacroiliac region, pubic rami, and pubic symphysis. Lateral compaction of pelvis generally ends in fracture via both pubic rami orfracture of pubic ramus on 1 side connected with dislocation of pubic symphysis. Anteroposterior compaction can cause dislocation of pubic symphysis or fracture via pubic rami escorted by dislocation of the sacroiliac joints. The displacement of part of the pelvic ring signals the ring is broken at 2 areas. The soft tissues likely to injure in pelvic fracture are urinary bladder, urethra, and rectum.
