Purpose:The aim of this study is to discuss the results of different intramedullary devices used in the management of paediatric radial neck fractures and to suggest methods to avoid the pitfalls of the technique.Methods:Thirty patients with isolated Judet Ⅲll and Ⅳ fractures were included in this prospective study.Judet Ⅰ and Ⅱ fractures and radial neck fractures associated with other injuries were excluded.The final results were graded using the Metaizeau functional scoring system and Oxford Elbow Score.Results:The functional result was good to excellent in 24 of 30 cases (80％).The mean Oxford Elbow Score was 44.32.The mean follow-up was 40.11 months.The complications seen were radiocapitellar joint penetration-6 cases at mean 4.87 weeks,redisplacement-6,radial epiphyseal sclerosis-5,and heterotopic ossification-1 case.Conclusion:Intramedullary K wires may result in radiocapitellar joint penetration.Titanium Elastic Nail System should not be used as purely fixation devices as they may not prevent redisplacement.Regular follow-up until at least 6 weeks is essential.Patients who have a Judet Ⅳ fracture and need open reduction should be given a guarded prognosis.The paper highlights the pitfalls of the technique and makes recommendations regarding the type of implant,follow-up and patient counselling in Judet Ⅳ fractures.
