Bladder rupture and urethral disruption are relatively common injuries associated with pelvic trauma; however, bladder herniation into a public symphysis diastasis is an unusual sequelae of pelvic trauma. We report a case of anterior bladder wall herniation into a traumatic pubic diastasis and review the literature. Recommendations focusing on avoiding possible urinary bladder complications associated with closed reduction and external fixation of the diastasis are offered.
