An 8-year-old Cameroonian boy with no significant past history was brought to our emergency service following a road traffic accident. On crossing a road, he was knocked down by an oncoming motorbike weighing approximately 125 kg, medium sized, and traveling at moderate speed. The motorbike fell on the boy with the handlebar catching him in the abdomen as its rider lost control. He sustained a lesion to the head with no initial loss of consciousness. On arrival, he complained of pain in his head and a swelling in the left upper quadrant of his abdomen.\nOn examination, he was conscious, with a Glasgow coma score of 15/15, blood pressure of 119/83 mmHg, pulse of 90 beats per minute, respiratory rate of 18 breaths per minute, temperature of 37.3 °C; he was 96 cm tall and weighed 26 kg. There was a 2 cm laceration in the occipital region of his head, and a swelling in his left lumbar region with mild bruising of the overlying skin (Fig. ). The swelling was reducible and disappeared in the supine position. There was no guarding and no rebound tenderness. He had normal bowel sounds on auscultation and the rest of the examination was unremarkable.\nA diagnosis of mild head injury and a handlebar hernia was made. After resuscitation, his scalp laceration was closed with a one point suture and he was programmed for surgery for the handlebar hernia the next day. A surgical exploration of the area showed a 7 cm laceration of his lateral abdominal wall (Fig. ), running from the external oblique aponeurosis through all the muscle layers to his peritoneum with loops of small bowel present in the opening. There was no blood or feces in the area immediately surrounding the lesion. Exploration of the bowel loops closest to the opening did not reveal signs of intra-abdominal injury. The abdominal wall defect was repaired in layers. The abdominal incision was closed in a standard manner. His postoperative period was uneventful. He was discharged on postoperative day 9 and scheduled 2 weeks later for a follow-up visit, but unfortunately was lost to follow-up.
A 6-year-old boy was admitted to the emergency department 3 days after a bicycle accident. The handlebar of his bicycle traumatized his abdominal wall above the left iliac crest. Twelve hours before the admission he noticed a palpable mass and a minor bruising to this specific point (Fig. ).\nThe physical examination revealed the presence of a painless swelling measuring 8 × 3 cm2 and did not reveal any pathological sign from the abdomen. The swelling was reducible, disappeared in supine position and increased by coughing. The diagnosis of a HH was suspected and confirmed by ultrasound that showed the disruption of internal and external oblique and transverse muscle (6 × 1.5 cm2) and the projection of omentum through the hernia without other associated internal organ injuries (Fig. ). The hematological and biochemical tests were normal. We suggested the admission of the child in our clinic for further clinical monitoring but the parents denied.\nThe reassessment after 2 weeks of rest at home showed an obvious size reduction of the hernia. Because of the significant size difference a MRI evaluation was decided, that confirmed that the disruption size was 3 × 0.7 cm2. In the follow up a month later, the hernia was no longer palpable and the ultrasonography identified a defect <2 mm without herniation.
