O33: Maternal care for known or suspected disproportion
O33.4: Maternal care for disproportion of mixed maternal and fetal 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.
There are various reasons why the size of your pelvis and the size of your child are not a good match. There are reasons for this both with you and with your child. For example, the mother’s pelvis can be narrower than usual, or be unusually shaped. The child may be unusually big or have a particularly large head.
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.
