Your pelvis was broken and was surgically stabilized using devices.

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.

You had an operation to have the fragments of your pelvis returned to their normal position and put back together. Your pelvis was then stabilized within your body using a special fixation system.

The special fixation system involves inserting some screws through the skin from outside and into the pelvic bone. A fixation system is then used to join these to one another inside the body.
