Suture fixation versus tension band wiring in simple displaced olecranon fractures - a study protocol

Olecranon fractures, particularly the Mayo Type 2A two-part fracture, are typically treated with Kirschner wires (K-wires) and tension band wiring. While effective, this method is associated with a high complication risk, leading to reoperations. Recently, new suture fixation techniques have been described that do not involve the insertion of metal. This new technique may mitigate risks associated with K-wires and tension band wiring without impacting healing or function. This study compares the reoperation rate and outcome of suture fixation with traditional tension band wiring.

This is a prospective, randomised, double-blinded, multicentre study. The allocation ratio is 1:1, and the groups are parallel. A total of 88 adult participants will be recruited. Participants will be assigned to receive either suture fixation or traditional tension band wiring. Follow-up is one year. The primary outcome is the reoperation rate. Secondary outcome measures include the Disabilities of the Arm, Shoulder and Hand (DASH), the EuroQol-5 Dimensions (EQ-5D) score, radiological outcomes and complications.

There is room for improvement in treating Mayo Type 2A fractures, and this study will allow us to investigate a new treatment method. The new suture fixation technique for treating olecranon fractures can potentially offer a similar or improved functional outcome compared to tension band wiring while lowering the reoperation rate significantly.

The study is initiated and conducted by the participating physicians within the financial framework of the participating departments.
