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.

Aims & Scope
The Journal of Children’s Orthopaedics is the official journal of the European Paediatric Orthopaedic Society (EPOS) and is published by The British Editorial Society of Bone & Joint Surgery.
It provides a forum for the advancement of the knowledge and education in paediatric orthopaedics and traumatology across geographical borders. It advocates an increased worldwide involvement in preventing and treating musculoskeletal diseases in children and adolescents.
The journal publishes high quality, peer-reviewed articles that focus on clinical practice, diagnosis and treatment of disorders unique to paediatric orthopaedics, as well as on basic and applied research. It aims to help physicians stay abreast of the latest and ever-changing developments in the field of paediatric orthopaedics and traumatology.
The journal welcomes original contributions submitted exclusively for review to the journal. This continuously published online journal is fully open access and will publish one print issue each year to coincide with the EPOS Annual Congress, featuring the meeting’s abstracts.
