In the last several decades, vehicle accidents have been the leading cause of long-shaft lower-limb fractures in children. These fractures often involve the tibia and fibula and are accompanied by skin and soft-tissue injuries of varying severity. This research aims to assess the efficacy of external fixators in the final treatment of open fractures in children. Methods: Fifteen patients with open long bone fractures were treated with external fixation at Benha University Hospital, with a median follow-up of 12 weeks. The present study validates previous research showing satisfactory functional and radiological outcomes utilising the external fixation approach. Patients' ages varied from 6-16 years old, with a mean of 9.603.07. Almost four out of five (73.3%) were males. Road traffic accidents accounted for 73.3% of all injury mechanisms, followed by the direct fall of a large item (6.6%) and localised trauma (1.3%). Gustilo grades 2 (53.3% of cases), 3a (33.3%), and 3b (6.7%) were the most common. The tibia was the most often broken bone (80%). A total of 87 minutes and 37 seconds were spent in surgery on average. Eighty percent of patients began ROM right away, whereas the remaining 20% did so within 2 weeks, and the other 7% did so within 5 months. Three patients began bearing weight immediately, two patients waited two weeks, and ten patients waited one month. The mean duration of a radiological union was 4.27 1.22 months. It took 4.63 1.14 months on average to get the fixator out. The most common complications were skin infections (60%) and stiffness (26.7%), followed by NV issues (13.3%), a pin fracture (6.7%), and a refracture of bone (6.7%).
