Importance of anterior humeral line for successful anatomical reduction in the surgical treatment of pediatric supracondylar humeral fractures

Anterior humeral line (AHL) and tilting angle (TA) are used for the assessment of pediatric elbow sagittal plane alignment in surgical treatment of pediatric supracondylar humeral fracture. However, few studies exist that compare the reliabilities between these parameters. The purpose of this study is to determine whether measurements of radiographic parameters are reliable and useful for achieving anatomical reduction. In the current study, we demonstrated that the identifying the AHL location involves a simple and reliable measurement compared with TA. The intraoperative AHL identification is a good indicator for achieving anatomical reduction.
