Abstract
Purpose
The elastic stable intramedullary nail has been recognized as an accepted technique for treating pediatric long bone fractures. The principle of the technique is "3-point support and fixation," and it should be followed to achieve the optimum outcome without implant failure and complications. However, tools have yet to be reported for pre-bending of the elastic stable intramedullary nail. This study aims to present a novel tool for pre-bending the elastic stable intramedullary nails and the results of using this tool by surgeons.
Methods
A designed case of femoral shaft fracture was provided to the participants. All participants were divided into three groups according to their experience with the elastic stable intramedullary nail technique: resident, fellow, and attending groups. The time of completing the pre-bending and coronal plane deviation of the nails after pre-bending was recorded. Statistical analysis compared the data in a conventional way and with the new tools in each group.
Results
A total of 30 physicians were recruited in this study. The pre-bending duration with the new tool was significantly shorter than that of the conventional method for all physicians (p < 0.001). The coronal plane deviation of nails after pre-bending by the new tool was significantly smaller than that of the conventional method for all physicians (p < 0.001).
Conclusion
This novel tool for elastic stable intramedullary nail pre-bending was convenient and easy to use in achieving the principal role of the elastic stable intramedullary nail technique. Physicians could reduce the coronal plane deviation when pre-bending elastic stable intramedullary nails, especially for physicians with less experience with the elastic stable intramedullary nail technique.
