Diastasis of the symphysis pubis

Preoperative radiograph of the pelvis in a child with classic bladder exstrophy. Note the diastasis of the symphysis pubis and the inability to view the obturator foramina (Top). Postoperative radiograph, after pelvic osteotomy, shows nice approximation of the symphysis pubis and a clear view of the obturator foramina (Bottom).
