Introduction: Supracondylar fractures are common in children, and appropriate treatment is crucial to avoid long-term complications. Methodology: The review included selected studies from SciELO, PubMed, and Scopus, covering randomized controlled trials, cohort studies, case series, and reviews, totaling 1,025 patients. Results: Nineteen studies were analyzed, showing significant variations in complication rates and efficacy between fixation methods such as crossed pins, plates, and intramedullary pins. Discussion: The comparison revealed that crossed pins have a lower risk of nerve injury, while plates offer better stability for complex fractures. However, all techniques have potential complications, including the need for early removal and infections. Conclusion: The choice of method should be individualized based on the fracture severity and patient profile, with rigorous follow-up to manage complications. Future research should explore new techniques and technologies to improve clinical outcomes and reduce complications.
