Complications and re-operation rate after tension-band wiring of olecranon fractures.

Tension-band wire fixation of olecranon fractures leads to a high re-operation rate because of the need to remove the metalware. This problem has commonly been thought to be related mainly to the backing-out of the Kirschner wires. A retrospective study was carried out in 55 patients with displaced olecranon fractures operated on with the tension-band wiring technique, in whom there was an overall 71.7% re-operation rate. Complications were few and minor in most patients. The main reason for the removal of the metalware was a direct complaint from the patient (in 61.3% of all removals). A literature review analyzing the causes of metalware removal is also presented.
