O33: Maternal care for known or suspected disproportion
O33.8: Maternal care for disproportion of other origin
In the pelvis there are various pelvic bones. At the back of the body the pelvic bones are connected to the sacrum of the spinal column. There is a joint on either side of the sacrum for this purpose. The pelvic bones plus the sacrum form the bony pelvic ring or girdle. In front, the pelvic bones are tightly joined to one another by ligaments and cartilage fiber.
If the size of the pelvis and the child are not a good match, this can cause problems and, for example, make the birth take longer or make a Caesarean necessary.
