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 nearly 7-year-old boy, with no relevant past history, visited our emergency department with abdominal pain and swelling after a fall from his bike. Whilst riding his bike, he had fallen and his abdomen had landed on the handlebar. Immediately after the accident, his mother noticed a swelling where the handlebar had hit his abdomen. They visited the general practitioner on call who subsequently sent him to our emergency department. Apart from pain, he had no other complaints. On physical examination, he seemed to be not ill and he was haemodynamically stable. Examination of the abdomen showed a circular contusion of the skin several centimetres below the umbilicus just on the right of the midline (Fig. ). On palpation, a clear defect of the rectus fascia could be felt. There were no signs of peritonitis suggesting an enteral lesion. He was admitted for observation and discharged the following morning. He was scheduled for surgery 1 week later. During the operation, a skin-line incision was performed over the fascia defect, revealing a rupture of the musculus rectus abdominis, as well as a total rupture of the right rectus fascia (Fig. ). The rectus sheath was closed with a continuous Vicryl suture. The muscle defect was approximated with interrupted Vicryl sutures. The skin was closed intracutaneously. He was discharged the following day and recovered uneventfully.
