Recurrent supracondylar humerus fracture following prior malunion.
In this report, two patients sustained a recurrent supracondylar humerus fracture following malunion of a previous supracondylar humerus fracture. The patients were treated for their first fracture at 5 and 6 years of age, respectively. One underwent open reduction with percutaneous pinning, and the other was treated with closed reduction with casting. Both patients healed in a moderate degree of extension after the first fracture. Two years later, both sustained a second fracture of the supracondylar humerus. Both had closed reduction with percutaneous pinning and went on to heal uneventfully. We speculate that ensuing post-traumatic extension deformity may accentuate a child's tendency for elbow hyperextension. Extension malunion may place the child at increased risk for a second fracture via similar mechanisms of injury.
