OPS-Code 5-782.5d:

You have had altered bone tissue removed from your pelvic bones.

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.

There are various soft tissues around the pelvic bones. Soft tissue includes muscles, fatty tissue and connective tissue, for example. In addition to the altered bone tissue, you also had soft tissue from the area surrounding the pelvic bones removed. The operation involved cutting right through a pelvic bone. The pelvic bone was then put back together.
