(A) Anteroposterior and (B) lateral elbow radiographs of a 5-year-old female patient with Gartland type 3 supracondylar humerus fracture. (C) The patient was treated with closed reduction and percutaneous pinning. Postoperative Baumann angle was measured by calculating the angle between the longitudinal axis of the humeral shaft and the line along the open capitellar physis. The patient's Bauman angle was calculated as 72 degrees. (D) Postoperative lateral capitellohumeral angle (LCHA) was measured by calculating the angle between the line along the anterior border of the distal humeral shaft (yellow line) and the line along the open capitellar physis (red line) on the lateral radiographs. The patient's LCHA was calculated as 54 degrees. Anterior humeral line (yellow line) passed the mid-third of capitellum (perfect reduction)
