Introduction: Femoral diaphysis fractures are the second most common fractures influencing the lower extremity in children. They occur after high-energy traumas. Surgical treatment has come into prominence over the last 10 years to enhance patient compliance and early mobilization. Objective: We prepared this study to present an example of trauma which may lead to serious permanent disability in pediatric patients and attract attention to the precautions to be taken on this issue. Case: A five (5)-year-old male patient was evaluated in the emergency department with his older brother after a motorcycle accident. The vital signs of the patient with an isolated femoral trauma were found stable. His hemogram and biochemical values were normal. Orthopedic consultation was requested for the patient with an isolated femoral distal diaphysis fracture. He was hospitalized by an orthopedic consultant physician. He was taken into surgery. Fixation was performed surgically with a plate-screw system. The patient was discharged without complications. Conclusion: Since large bone fractures may occur in pediatric patients after a high-energy trauma such as a motorcycle accident, pediatric patients should be legally prohibited from getting on a motorcycle or getting on a motorcycle without protective equipment.
