Waddell's triad is a specific pattern of injuries commonly associated with pediatric trauma, particularly in children who have been struck by vehicles. The term describes a combination of injuries that typically includes injuries to the femur, head, and chest. When a child is hit by a car, the initial impact often causes a femoral injury due to the lower extremities being more vulnerable at that level. Following this, the mechanism of the collision can lead to secondary injuries as the child is thrown onto the hood or ground, resulting in impact to the head and chest areas. This triadic injury pattern is significant because it not only helps in diagnosing the extent of injuries but also informs the approach needed for treatment and management of these patients. Understanding this triad is crucial for emergency medical professionals, as it allows for a comprehensive assessment of the patient and identifies potential life-threatening conditions that could arise from each of these areas.
