Outcome of titanium elastic nailing in pediatric subtrochanteric femur fractures: A case series

Introduction: Subtrochanteric femur fractures are difficult injuries to treat in children. Although elastic stable intramedullary nails are commonly used for pediatric femur shaft fractures, there is little information on their effectiveness for managing pediatric subtrochanteric femur fractures. We are not aware of any published study that defines outcome of titanium elastic nail in treatment of pediatric subtrochanteric femur fractures. We, in this study, evaluated radiographic union rates, fracture alignment, and complications after titanium elastic nailing of pediatric subtrochanteric femur fractures. Materials and Methods: A total of 10 cases of pediatric subtrochanteric femur fractures were admitted in our department between November 2016 and April 2018. This prospective study included 8 males and 2 females, with a mean age of 7.9 years (5-11 years). All patients were treated with elastic stable intramedullary nails and had complete follow up until clinical and radiographic union. Results: All patients had clinical healing with full weight-bearing and the functional outcome scores were satisfactory. No cases of infection were reported at the time of the last follow-up visit. Complications included malunion (n = 1), irritation (n = 1) at nail insertion site, and limb length discrepancy (n = 1). Despite these complications, there were 7 (70%) excellent, 3 (30%) satisfactory, and none with poor outcomes. Conclusions: Titanium elastic nailing is an important option for treating subtrochanteric femur fractures in children with low complication rates.
