5-790.6d:

Your pelvis was broken and it has been surgically stabilized using 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. In front, the two pelvic bones are tightly joined to one another by ligaments and cartilage fiber.

The fragments of your pelvic bone were put back in their normal place, and a special fixation system was used to join and stabilize them. The special fixation system involves inserting metal pins or screws through the skin from outside and into the pelvic bone. These are then joined to one another outside the body using a holding system.
