Introduction: Among the elbow fractures, the most common elbow fracture observed in children are the supracondylar humeral fracture. The advancement of modern surgical techniques has reduced the incidence rate of compartment syndrome and malunion. For the treatment of supracondylar humeral fractures, techniques such as closed reduction, traction, splint closed reduction, open reduction, k-wire fixation, and percutaneous pinning are used. There are different approaches that are applied for open reduction method which include double incision method (lateral and medial), medial, anterior, posterior and lateral approach. Till date among all these approaches, the posterior approach via muscles of triceps has produced very good results. Different studies have been conducted to compare the anterior and posterior approaches of surgical treatment. Aim: To compare the results of posterior and lateral surgical approaches while treating the type III supracondylar humeral fracture in children. Methodology: This study included 82 children, who had undergone the surgical treatment, 52 patients were treated by the posterior approach, and 30 patients were treated by the lateral approach. Both the groups had their follow up till 6 months postoperatively. Results: It was observed that the posterior approach had a very short surgery time as compared to the lateral approach. The results obtained according to the Flynn__ampersandsignrsquo;s criteria were 80.7% in the posterior group and 80% in the lateral group, and no statistical significance was observed between the two groups. Conclusion: The posterior approach had shorter operating time as compared to the lateral approach, however, no statistical significance was determined between the two groups in terms of functional results and complications.
