Loop Anchor Tension Band Fixation for Olecranon Fractures and Chevron Olecranon Osteotomy
Although tension band wiring is effective for treating olecranon fractures, it is associated with a high reoperation rate because of hardware-related problems. The loop anchor tension band technique is a novel modification of the Arbeitsgemeinschaft für Osteosynthesefragen (AO)-modified tension band wiring technique.
