Background: The most common fractures among long bones are femoral fractures. Femoral shaft fractures account for 1.6% of all paediatric bony injuries. Children in the age group of 5-15 years are treated with either traction, hip spica, flexible/elastic stable retrograde intramedullary nail, or external fixators. We conducted a clinical prospective study on the use of Titanium Elastic Nailing System (TENS) for the treatment of femoral shaft fractures in children. Materials & methods: The study was conducted in a tertiary care centre from November 2019 to December 2022. A total of 30 subjects within the age group of five years to fifteen years were enrolled. The Inclusion Criteria were a) Age group of 5-15 years, b) Recent fracture of femur shaft c) Transverse, short oblique, minimally comminuted fractures. Preoperative radiographic examination was done in all the patients. All patients underwent surgery as early as possible with an average 3days from the day of admission. The results were evaluated using Flynn’s scoring criteria. Results: After 23 months of follow up all thirty patients were available for evaluation. Radiological union were achieved in a mean time of 10 weeks. Mean duration of hospital stay was 14 days. According to Flynn’s criteria of TENS outcome score results were excellent in 70% patients, Satisfactory in 26.7% patients, Poor in 3.3% patient. All patients had early return to school. Conclusion: Titanium elastic nailing is simple, rapid & effective treatment for displaced pediatric femoral shaft fractures.
