Objective To analyze the application value of the 20 degree upper arm tilt position photography method in the treatment of humeral lateral condylar fractures.Methods A total of 50 children with humeral epicondylar fractures admitted to Jiangxi Provincial Children's Hospital from June 2022 to May 2023 were selected as the study subjects,all of whom were photographed using traditional orthopedic and 20 degree upper arm tilt positions.Surgical results were taken as the gold standard.According to the Jakob classification method,a secondary evaluation was conducted to measure the displacement distance between the inner and outer sides of the bone blocks in the X-ray plain films of different postures.Results Among the 50 children with humeral epicondylar fractures,after two types of photography,in 50 children with lateral condyle fracture,the Jakob classification of standard photography was 29 with degree Ⅰ,17 with degree Ⅱ,and 4 with degree Ⅲ,and Jakob classification of 20 degree upper arm tilt position photography method was 19 with degree Ⅰ,27 with degree Ⅱ,and 4 with degree Ⅲ.After measurement,it could be seen that the ectopic distance obtained by the 20 degree upper arm tilt position photography method was greater than that obtained by the standard position method,and the difference was statistically significant(P＜0.05).The accuracy of the 20 degree upper arm tilt position photography method was higher than that of the standard position photography method,with statistical significance(P＜0.05).Among the 50 children with humeral epicondyle fracture,the surgical results were the gold standard,45 cases had correct results and 5 had wrong results,and the sensitivity of the 20 degree upper arm tilt position photography method was 97.73％,the specificity was 66.67％and the accuracy was 94.00％.Conclusion Using the 20 degree upper arm tilt position photography method in the diagnosis of humeral epicondylar fractures can quickly display the degree of bone block displacement in pediatric patients,improve the accuracy of diagnosis,and provide favorable reference basis for clinical treatment.
