A 48-year-old woman presented with a hernia through the center of her pubic symphysis 6 months after conservative treatment of an open-book fracture of the pelvis. This was repaired laparoscopically with a prosthetic mesh using a transperitoneal approach. Hernia through the pubic symphysis is a rare complication after traumatic symphysis diastasis, but repair using the laparoscopic approach is feasible and associated with rapid recovery from surgery.
