O26.7: Subluxation of symphysis (pubis) in pregnancy, childbirth and the puerperium

The front part where your two pelvic bones are connected has loosened or slightly shifted.

The pelvis is made up of different bones. There are 3 bones on each side which each merge to form one large pelvic bone. A joint connects these two large pelvic bones to the sacrum at the back of the body. The sacrum is part of the lower spine. The two pelvic bones plus the sacrum form a bony pelvic ring or girdle. In front, the two pelvic bones are tightly joined to one another by ligaments and cartilage fiber.

During pregnancy, the firm connection at the front, between the two large pelvic bones, can loosen a little. This can be normal and encouraged by certain pregnancy messenger substances. In your case, however, this connection has loosened a lot, and the gap between the two large pelvic bones is wider than normal.

When the connection between the large pelvic bones loosens, these bones may become misaligned. You can then have various problems. These include pain when climbing up the stairs, for example. You may find that you waddle slightly.

The symptoms can occur in pregnancy or after the birth.
