OPS-Code 5-789.3d:

You had another operation on your pelvic bone. In the past, one or more pelvic bones were stabilized with aids.

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. At the front, the two pelvic bones are firmly connected to each other by ligaments and cartilage fibers.

To stabilize bones or parts of bones, various aids can be used. They can be made of metal or plastic, for example. During a repeat operation, the aids can be checked and if necessary reattached. However, your aids were not replaced.
