## Abstract

The patient in this case report is a 17-year-old male individual who presented as a victim of an assault by knife attack that resulted in a cut below the left elbow, and the knife was stuck at the site of injury. He complained of pain at the site of injury, in addition to an inability to pull out the knife. Physical examination showed a knife stuck below the elbow with normal sensation, pulsations, and range of motion. Laboratory investigations and an X-ray were ordered for the patient. X-ray showed a penetrating knife wound through the left forearm, passing through the radius and ulna, with swelling of the overlying soft tissues of the forearm. The patient was shifted to the operating theater for limb-saving surgery. Intraoperative exploration showed a penetrating wound by a knife through the left forearm, passing through the radius and injuring one of the venae comitantes of the ulnar artery and some perforators. The knife was removed, and an X-ray was taken to check for a fracture of the radius, which showed only a through-and-through tract with no obvious fracture. Hemostasis was achieved, and the wound was closed. The patient was discharged with regular follow-up appointments.
