AbstractPenetrating rebar injuries are extremely rare occurrences, but they are very life-threatening, particularly when involving the thoracic and abdominal cavities. The surgical approach to these traumatic injuries depends upon the length and diameter of the rebar as well as the path of penetration into the abdominal and thoracic regions. Due to the highly uncommon occurrence of penetrating rebar injuries, there is very limited information and studies pertaining to this topic in the literature. In this case report, we present a 43-year-old male patient sustaining a rebar penetrating injury, with the entry site being the left flank and the exit site being the anterior left chest. Upon arrival, the patient was emergently taken to the operating room and underwent simultaneous exploratory laparotomy and a left thoracotomy. The operation was successful in removing the rebar and the patient survived.
