A traumatic abdominal wall hernia (TAWH) caused by a handlebar collision is very rare. It is difficult for the emergency physician to exclude the possibility of mesenteric or intestinal injuries when viewing handlebar trauma. Because TAWH may have no other clinical symptoms, early recognition and differentiation from haematoma is important. An unusual case of TAWH caused by a handlebar injury is reported, where a multi-layer muscular defect was found along with a segment of incarcerated jejunum and omentum. The latest literature is reviewed, and valuable ideas on the management of blunt abdominal trauma with TAWH are shared.
