The definitive treatment of paediatric femoral diaphyseal fractures remains controversial, although management of such fractures has gradually evolved in the past two decades towards operative approach because of a desire for more rapid recovery and reintegration of the patients. Modalities of treatment vary mostly according to age, with fracture pattern and site having a lesser impact. We used TEN (Titanium Elastic Nailing) for the management of femoral diaphyseal fractures of children in 5-16yrs age group with transverse fractures of femur and weight<50kg. Description of Technique: Two flexible nails, made of titanium are inserted in a retrograde fashion through small incisions over the distal metaphysis, 2 cm above the physis. The size of the nails is selected based on the diameter of the patient’s intramedullary canal on preoperative radiographs. Methods: We reviewed all displaced pediatric femoral diaphyseal fractures of children in 5-16yrs age group with transese fracture of femur and weight<50kg treated at IMS&SUM Hospital, Bhubaneswar from october 2016 through September 2018.We included 54 fractures(30 boys,24 girls) meeting criteria for inclusion. These fractures were Proximal 3^rd (n=6), Middle 3^rd (n=45), Lower 3^rd (n=3).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: Excellent results were seen in 50 patients, good in 4 patients. All the fractures healed with average time to union of 6.5 weeks. Mean duration of hospital stay was 4.5 days. Full weight bearing was achieved in all cases in the mean time of 6.5 weeks. Conclusions: Flexible nailing is a safe and reliable method of fixation for femoral shaft fractures of children 5-16 yrs age and weight<50kg. They do not provide rigid fixation, but allow enough stability to permit for early mobilization and fracture healing. It is safe less invasive with fewer complications and early return of children to school.
