Aids have been removed from your pelvic bone.

To stabilize bones or parts of bones, various aids can be used. They can be made of metal or plastic, for example.

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.

Long pins have been removed from your pelvic bone. Long pins like these are used to stabilize the pelvic bone from within. The long nails are inserted through bones and join these bones together. Joints, for example, can be temporarily reinforced like this.
