However, the preferred treatment option among children and adolescents is still controversial. Methods: We report four cases of STFs in school-aged pediatric patients, treated with an adult proximal humerus LP. Results: Based on the Flynn scoring system at the last follow-up visit, all patients exhibited excellent clinical outcomes, along with satisfactory radiological outcomes based on the Beaty scoring system. There were no complications. Conclusion: Our findings suggest the efficacy of using adult proximal humerus LPs in treating pediatric STFs. The advantage of these plates lies in their ability to accommodate many screws at appropriate positions and angles without damaging the physis. This approach holds promise for the management of pediatric STFs. https://jost.tums.ac.ir/index.php/jost/article/view/517 https://jost.tums.ac.ir/index.php/jost/article/download/517/371
