Background: Paediatric femoral shaft fractures are common in orthopaedic practice and can be managed using various modalities, each with its advantages and disadvantages. The Titanium Elastic Nailing System has emerged as a promising treatment option, offering potential advantages over traditional methods. Objective: This study aimed to evaluate the functional and radiological outcomes and operative complications of paediatric femoral shaft fractures treated with the Titanium Elastic Nailing System. Methods: A prospective interventional study was conducted from July 2020 to July 2021. Thirty children aged 6-14 years (mean age 11.32 ±3.76) were selected using purposive sampling and strict inclusion/exclusion criteria. Patients were followed up for at least 24 weeks at four-week intervals, and outcomes were assessed using Flynn's TEN scoring criteria. Results: All 30 patients completed the study. Radiological union was achieved in 80.0% of cases within 7-10 weeks, with 90.0% of patients able to bear full weight by the 12th week. Minor complications occurred in 20.0% of cases, while no major complications were reported. 80.0% of cases had excellent outcomes, 20.0% were satisfactory, and no poor outcomes were observed. Conclusion: The Titanium Elastic Nailing System is an excellent method for treating paediatric femoral shaft fractures, demonstrating high rates of radiological union and functional recovery with a low incidence of complications.
