O65.5: Obstructed labour due to abnormality of maternal pelvic organs

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 different levels within the pelvis. During the birth the child must pass through the different levels. In a normal birth the child passes through the pelvis head first. If the child’s head is to be able to pass through the different levels, it has to turn in different places.

There are different organs in the pelvis. These include, for example, the last section of the intestine, the bladder and the womb. During the birth the child must go past these organs. The birth canal, which the child uses to pass through the pelvis, is also in the pelvis. You have pelvic organs or parts of your birth canal that have changed.

There were problems during the birth due to the changes in your pelvic area. Problems like these can make a birth take longer than usual. It may also be the case that the child cannot then be born in the usual way, but that a Caesarean is required.
