Treatment of pseudarthroses of the olecranon with the anatomical hook plate

We report the results in seven patients treated surgically for nonunion of the olecranon. Four nonunions occurred after primary treatment with tension band wiring and three nonunions occurred after open reduction internal fixation with plates and screws or lag screws only. All patients were treated with cancellous bone grafting and open reduction internal fixation using anatomical hook plates. All nonunions united within 6 months after the treatment. In all patients the range of motion of the elbow improved significantly.
