There are four types of the female pelvis, namely:
Shown below are the types of female pelvis (normal and its variations) along with their features.
Categorised according to Morphology, the pelvis is split into the following 4 types:
- Mesatipellic (normal): When the transverse diameter of the pelvic inlet is somewhat more in relation to the anteroposterior diameter.
- Brachypellic (android type): When the anteroposterior diameter of the pelvic inlet is marginally more in relation to the transverse diameter.
- Platypellic: When the transverse diameter of the pelvic inlet is considerably greater in relation to the anteroposterior diameter.
- Dolichopellic: When the anteroposterior diameter of the pelvic inlet is far more than the transverse diameter.
Fractures of The Pelvis
The pelvis is a ring-like structure. It’s quite powerful and generally takes an immediate violence of high velocity to fracture it. The feeble sites of the ring are sacroiliac region, pubic rami, and pubic symphysis. Lateral compaction of pelvis generally ends in fracture via both pubic rami or fracture 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.
