Background:This study was conducted to assess the functional outcome of pediatric femur fractures treated with Ender nailing in the age group of 5 to 16 years. Materials and Methods:Using a specific proforma, we gathered the patient records. All of the patients' necessary investigations had been completed. Patients were checked on every six, twelve, and twenty-four weeks. Patients were routinely examined at follow-ups using x-rays and clinical results. In compliance with the proforma, documentation was created. The patient's respiration, circulation, and airway were evaluated as soon as they were taken to casualty. After then, a thorough examination was done to rule out any other serious injuries. plain radiographs of the AP as well as lateral views of the thigh, encompassing the hip and knee joints, in order to evaluate the fracture's size, geometry, and degree of comminution. Results:A total of 50 subjects were evaluated. Among them, 70 percent of the subjects were males while the remaining were females. Road traffic accidents were the major etiological factor. Transverse fractures occurred in majority of the cases. While assessing the range of motion, good range of motion was seen in 86 percent of the patients while mild and gross restriction was seen in 6 percent and 8 percent of the patients respectively. While evaluating the complications, superficial infection, knee stiffness, limb length discrepancy, angulation and nail impingement were seen in 8 percent, 14 percent, 10 percent, 4 percent and 4 percent of the patients respectively. Conclusion:Ender nailing system is an effective method with minimal complications and good range of motion.
