O65.0: Obstructed labour due to deformed pelvis

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.

The shape of your pelvis has changed. The shape of the pelvis can be changed because, for example, the sacrum is unusually shaped. The pelvic bone may also be shaped differently.

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.

When the pelvis has a different shape, the child’s head may not be able to pass through certain parts of the pelvis as easily. It may also be that the head is unable to turn as easily as normal.

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.
