Official title: The With Or Without Olecranon K-wire (WOW OK) Trial of Tension Band Wire Fixation Versus Cerclage Fixation Without K-wires in Displaced Stable Olecranon Fractures

Run by Region Skane · NCT05657899 · Data updated 2026-11-12

This study is testing which surgical method, cerclage fixation or tension band wiring, works better for treating certain types of elbow fractures in adults to see if it leads to fewer complications and re-operations.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with Mayo type 2a or 2b olecranon fractures seeking treatment at Skåne University Hospital.

Probably not a fit

Patients with severe open fractures, those unable to provide informed consent, or those for whom non-operative treatment is indicated may not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of cerclage fixation versus tension band wiring in treating stable olecranon fractures classified as Mayo type 2a and 2b. Patients aged 18 and older at Skåne University Hospital will be randomly assigned to one of the two surgical methods. The study aims to determine which method results in lower re-operation and complication rates. Participants will be monitored by physiotherapists throughout the recovery process.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced need for re-operations in patients with olecranon fractures.

How similar studies have gone: Previous studies have suggested that cerclage fixation may yield lower re-operation rates compared to tension band wiring, indicating potential success for this approach.
