Aim
The purpose of this study was to assess treatment outcomes in children weighing 50 kg (110 pounds) or more with displaced femur shaft fractures treated by elastic stable intramedullary nailing (ESIN) and to identify potential correlations between nail size/medullary canal diameter ratio and outcome.
Methods
Twenty out of 117 consecutive children surgically treated by ESIN for displaced fractures of the femoral shaft with no associated neurovascular injury weighed 50 kg (110 pounds) or more. All patients underwent regular clinical and radiographic follow-up for at least one year after their index surgery.
Results
The average patient age at the time of injury was 13.1 years (25th and 75th interquartile range [IQR] = 11.7–14.5). The mean follow-up was 27.4 months (IQR = 18.4–36.8). Overall, nine (45 %) adverse events were observed. The rate of complications was higher among children weighting 55 kg and over (67 %) than in children weighing less than 55 kg (35 %) and among children aged 13 years old or older (72 %) than among children younger than 13 years old (11 %).
Discussion
Femoral shaft fractures in children and adolescents weighing 50 kg (110 pounds) and over and older than ten years of age have an increased rate of complications.
Conclusion
Heavier patients have a greater chance of complications. In particular, patients younger than 13 years old and weighing less than 55 kg can be safely managed with ESIN, but older and heavier patients should preferably be treated with rigid fixation systems due to a greater complication rate. However, further studies are needed to consolidate the conclusions.
