AO tension-band osteosynthesis of displaced olecranon fractures.

This study reviewed 31 patients who underwent AO tension-band osteosynthesis of displaced olecranon fractures. Thirteen fractures were comminuted. Postoperative immobilization was short, and the median hospital stay was 3 days. In 2 patients, the stainless steel wire broke and required replacement. In 13 patients, the osteosynthesis material was removed after healing because of pain at the tip of the elbow; this did not influence the final result. Median time out of work was 12 weeks. There was no significant loss of elbow power. There was satisfactory mobility, function, and absence of pain. There were 29 good and 2 fair clinical results. Anatomic reduction was achieved in 24 elbows. Possible arthrosis was detected at follow-up in 5 elbows but these patients had a good clinical result. AO tension-band osteosynthesis of displaced olecranon fractures yields good clinical medium-term results with few serious complications.
