During the period 2004–2009, 35 children were admitted to the emergency department,(24 males:11 females), aged 3–14 years old,(MEAN 8,45 years), with supracondylar humeral fractures (33 extension type and 2 flexion type). All fractures were closed and result of sports injuries or games and were treated with closed reduction under general anesthesia and percutaneous k-w fixation. The postoperative follow-up lasted from 6 months to 4 years. The Bauman’s angle was evaluated postoperatively on the operated and normal elbow and was 76, 6 ±1° and 74, 7 ±0, 6°. According to Flynn’s criteria the functional outcome was excellent in 29 cases. In 6 cases where the Bauman’s angle was greater than 10–15° there has been observed varus deformity (4 cases), valgus deformity (1 case), and flexion deficit (1 case). The percutaneous k-w fixation and preservation of Bauman’s angle with carrying angle too, on supracondylar humeral fractures on children is a safe solution to avoid future complications.
