Supracondylar fractures of humerus are the most common fractures in children. The management of severely displaced, unstable fractures of the humerus in children continues to be controversial. We undertook a retrospective study of 48 children with displaced supracondylar fractures (8 were treated with plaster and 40 with cross percutaneous Kirschner wire pinning). Only three children were treated with open reduction and percutaneous cross-pin fixation. Clinical outcome was evaluated by loss of elbow motion and change of carrying angle. According to Flynn s criteria, results were good or excellent in 93.7% patients. The cubitus varus is the most frequent long-term complication (16.7%). Closed reduction with percutaneous pin fixation is believed to represent a safe, reliable, and efficient method of managing displaced supracondylar fractures.
