OPS-Code 5-789.0d:

The periosteum was sutured during an operation on your pelvic bone.

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.

The periosteum is a thin layer that almost completely envelops the bones. The periosteum has numerous functions, including supplying the bones with nutrients. There are also nerves within it, making it highly sensitive to pain.
