Which of the following is NOT a component of Waddell's triad?

Waddell's triad refers to a specific pattern of injuries typically seen in pediatric patients who have been struck by a motor vehicle. The classic components of this triad include a femur fracture, intra-abdominal injury, and head injury.

The presence of a femur fracture is commonly associated with the impact from the vehicle, and it often highlights the direct force involved in such accidents. Intra-abdominal injuries, such as organ lacerations, are also prevalent due to the blunt force trauma experienced in these incidents. Head injuries are significant in this triad because they represent the potential for severe neurological damage that can occur during such a traumatic event.

On the other hand, spinal injuries are not traditionally considered a component of Waddell's triad. While spinal injuries can occur in similar traumatic scenarios, they do not form part of this specific triad of injuries. Thus, spinal injury is the correct answer to identify what is not included in Waddell's triad. Understanding the correct components helps in the recognition and management of potential injuries in pediatric trauma cases.
