Traumatic abdominal wall hernia in children caused by a bicycle handlebar is a rare injury. This is a case report of a 15-year-old boy with a traumatic hernia in the right groin, where a physical examination revealed a small bulge in the right inguinal region, and an ultrasonography confirmed the diagnosis. The condition was initially treated conservatively. However, the patient had surgery performed three days later because of pain. Surgical repair with open layered closure is the preferred method. Laparoscopic sutured repair may also be performed, especially if diagnostic laparoscopy is performed anyway.
