BackgroundStudies have demonstrated a higher risk of complications when children with fractures in the proximal third of the femur and length-unstable fractures are treated with titanium elastic nails. Alternative treatment methods include open plating and submuscular plating. We are not aware of any published studies that directly compare titanium elastic nail and plate fixation of pediatric subtrochanteric femur fractures. The purpose of the present study was to retrospectively compare the outcomes and complications of titanium elastic nail and plate fixation of subtrochanteric femur fractures in children and young adolescents.MethodsA total of 54 children aged 5 to 12 years with subtrochanteric femur fractures treated with titanium elastic nails or plating at 2 institutions between 2003 and 2010 were identified. We retrospectively compared 25 children treated with titanium elastic nails to 29 children treated with either open plating or submuscular plating. Similar to previous studies, a fracture that was located within 10% of the total femur length below the lesser trochanter was classified as subtrochanteric. Outcomes were classified as excellent, satisfactory, or poor. A major complication was defined as any complication that led to unplanned surgery. Minor complications were defined as complications that resolved with nonoperative treatment or did not require any treatment.ResultsOutcome scores were significantly better in the plating group (P=0.03), but both groups demonstrated high rates of excellent and satisfactory results. The overall complication rate was significantly higher in the titanium elastic nails group (48%; 12 of 25) when compared with the plating group (14%; 4 of 29) (P=0.008). Patients in the titanium elastic nails group were advanced to full weightbearing significantly earlier (6.6 vs. 9.9 wk) (P=0.005). The major complication rate, length of hospitalization, and time to radiographic union were similar for the 2 groups.ConclusionsOur results indicate that plate fixation of pediatric subtrochanteric femur fractures is associated with better outcome scores and a lower overall complication rate when compared with titanium elastic nails.Level Of EvidenceTherapeutic Level III.
